Summary:
Currently re-implements the dataloader for stateful datasets. Outstanding work:
- Refactor DataLoader and DataLoader2 to have common base classes and only differ in specifi pieces of logic,
- Figure out how to not duplicate the `MapDataset` logic for stateful vs. non-stateful

Summary:
This has 4 changes
1) propagate USE_SYSTEM_NCCL. Previously it was ignored and cmake always did a FindPackage
2) respect SCCACHE_DISABLE in our caffe2 sccache wrapper for circleci
3) use SCCACHE_DISABLE when building nccl, because it triggers the same bug as when using CCACHE (already tracked in https://github.com/pytorch/pytorch/issues/13362). This was hidden because we weren't respecting USE_SYSTEM_NCCL, and were never building nccl ourselves in CI
4) In one particular CI configuration (caffe2, cuda 8, cudnn 7), force USE_SYSTEM_NCCL=1. Building the bundled nccl triggers a bug in nvlink. I've done some investigation, but this looks like a tricky, preexisting bug, so rather than hold up this diff I'm tracking it separately in https://github.com/pytorch/pytorch/issues/14486

Summary:
export - print a method with python_print
import - import a method with import_method
We want to ensure:
export(g) == export(import(export(g)))
That is after after exporting/importing once, the graph will stay exactly
the same. This is less strict that g == import(export(g)) which would
require us to maintain a lot more information about the structure of the
IR and about the names of debug symbols.
This PR addresses this with the following fixes:
* print out double-precision numbers with high enough precision such
that they always parse in the same way
* when creating loop-carried dependencies, sort them
by variable name, ensuring a consistent order
* parse nan correctly
* DCE: remove unused outputs of if statements, and loop-carried dependencies
in loops that are dead both after the loop and inside the body of the
loop.
* Do not set uniqueName for variables whose names are _[0-9]+, these
are probably rare in user code, and we need a way to communicate
that we do not care about a variable name when re-parsing the graph.
Otherwise temporary variable names will jitter around.
* Expand the definition of a constant in printing code to None,
and family.
* Allow re-treeing to work as long as the only thing in its way is a
constant node. These do not have side effects but are sometimes
inserted in a different order when tracing compared to how we print them.
* Print all constant nodes out first in the order in which they are used_val
(or, if they are inlined, ensure they get assigned CONSTANT.cX number
in a consistent order). Cleanup tuples (this is done in the compiler,
but not in the tracer, leading to some tuple indexing jitter if not
done).
* use strtod_l, not std::stod which can throw exceptions
Other:
* Add REL_WITH_DEB_INFO to setup.py. It already existed for the
cmake files. Threading it into setup.py allows us to turn on
debug symbols with optimization everywhere.
* enable round trip testing for all generated graphs. This only adds
~6 seconds to total build time but tests printing for every graph.

Build of PyTorch tested by me in CentOS docker. PyTorch unit tests work mostly, however, a test in test_jit causes a python recursion error that seems to be due to the python2 on CentOS as we haven't ever seen this on Ubuntu - hence please do not enable unit tests.

Summary:
Pull Request resolved: https://github.com/pytorch/pytorch/pull/13342
This PR introduces a few new concepts:
- DeviceGuardImplInterface, and implementations for CPU and CUDA, which
provide a generic interface for interfacing with device and stream state,
without requiring a direct dependency on the code in question.
- InlineDeviceGuard, a general template for generating both specialized
and dynamically dispatched device guard implementations. Dynamic
dispatch is done by specializing it on a VirtualGuardImpl.
- Provide a device-independent DeviceGuard class, which can be used even
from CPU code. It uses the aforementioned dynamic dispatch.
- CUDA-specialized CUDAGuard class, which doesn't have a dynamic dispatch
but can only be used from CUDA.
- StreamGuard, which is the same as above, but for streams rather than
devices.
- Optional variants of all the aforementioned guards, which are a no-op if
no device/stream is specified
- CUDAMultiStreamGuard, specifically for the case when we want to set
a device on every guard.
There are some subtle semantic changes, which have been thoroughly documented
in the class definition.
BC-breaking changes:
- Move constructor/assignment have been removed from all device guard
implementations.
- In some cases where you previously wrote 'set_device' (or 'set_stream'), you now must write
'reset_device', because if you switch devices/device types, the stream/device on the
previous device is unset. This is different from previous behavior.
- CUDAGuard no longer handles streams, or multiple streams. Use CUDAStreamGuard
or CUDAMultiStreamGuard as appropriate for your use case.

Symbols in libgloo.a that are not used are ignored and don't end up in

depends on the gloo target, and it expects all libgloo.a symbols to be

libcaffe2.so remain undefined in libc10d.a.
To fix this, we link to libgloo.a when linking _C.so, such that any

Summary:
This PR implements a DataLoader API for the C++ frontend.
The components present in this API largely match the Python API. It consists of:
- `Dataset`s: Conceptually a function from a set of indices to a batch of examples;
- `Transform`s: A functional transformation of a dataset. A `Map<D, T>` for Dataset `D` and transform `T` is itself a dataset;
- `Sampler`s: Specify a strategy for generating indices for a new batch;
- A `DataLoader`, with the ability to automatically parallelize fetching of samples across multiple worker threads;
Note that collation functions fall naturally out of the `Map<Dataset, Transform>` abstraction.
Things that are missing right now that maybe should be added:
- Memory pinning for CUDA tensors
The API was designed to be generalizable to almost any kind of dataset, transform or sampling strategy, while providing a convenient API out of the box. To achieve this, it is quite heavily templatized on various possible input types.
There are many parts to this PR! Right now, I would like feedback on:
- Your impression of the general usability of the API;
- Your impression of which parts seem too complex or overthought;
- The implementation of the parallelization aspects of the DataLoader. I've followed the Python implementation in some matters, but also differ in others. I think my implementation is a little cleaner and decouples components slightly better than the Python dataloader.
I haven't added too many comments yet, as this is fresh out of the oven. Let me know if anything is unclear from the code itself.
There also aren't any tests yet. I will write a comprehensive test suite once we agree on the API and implementation.

This is mainly a codemod and not causing functional changes. If you find your job failing and trace back to this diff, usually it can be fixed by the following approaches:
(1) add //caffe2/c10:c10 to your dependency (or transitive dependency).
(2) change objects such as at::Error, at::Optional to the c10 namespace.
(3) change functions to the c10 namespace. Especially, caffe2::MakeString is not overridden by the unified c10::str function. Nothing else changes.
Please kindly consider not reverting this diff - it involves multiple rounds of rebasing and the fix is usually simple. Contact jiayq@ or AI Platform Dev for details.

Summary:
Currently the C++ API and C++ extensions are effectively two different, entirely orthogonal code paths. This PR unifies the C++ API with the C++ extension API by adding an element of Python binding support to the C++ API. This means the `torch/torch.h` included by C++ extensions, which currently routes to `torch/csrc/torch.h`, can now be rerouted to `torch/csrc/api/include/torch/torch.h` -- i.e. the main C++ API header. This header then includes Python binding support conditioned on a define (`TORCH_WITH_PYTHON_BINDINGS`), *which is only passed when building a C++ extension*.
Currently stacked on top of https://github.com/pytorch/pytorch/pull/11498
Why is this useful?
1. One less codepath. In particular, there has been trouble again and again due to the two `torch/torch.h` header files and ambiguity when both ended up in the include path. This is now fixed.
2. I have found that it is quite common to want to bind a C++ API module back into Python. This could be for simple experimentation, or to have your training loop in Python but your models in C++. This PR makes this easier by adding pybind11 support to the C++ API.
3. The C++ extension API simply becomes richer by gaining access to the C++ API headers.

Summary:
Python never closes shared library it `dlopen`s. This means that calling `load` or `load_inline` (i.e. building a JIT C++ extension) with the same C++ extension name twice in the same Python process will never re-load the library, even if the compiled source code and the underlying shared library have changed. The only way to circumvent this is to create a new library and load it under a new module name.
I fix this, of course, by introducing a layer of indirection. Loading a JIT C++ extension now goes through an `ExtensionVersioner`, which hashes the contents of the source files as well as build flags, and if this hash changed, bumps an internal version stored for each module name. A bump in the version will result in the ninja file being edited and a new shared library and effectively a new C++ extension to be compiled. For this the version name is appended as `_v<version>` to the extension name for all versions greater zero.
One caveat is that if you were to update your code many times and always re-load it in the same process, you may end up with quite a lot of shared library objects in your extension's folder under `/tmp`. I imagine this isn't too bad, since extensions are typically small and there isn't really a good way for us to garbage collect old libraries, since we don't know what still has handles to them.

Summary:
This speeds up incremental builds by doing the following changes:
- Uses `rsync` instead of `cp` (when `rsync` is found) which is a bit smarter in doing "maybe copy"
- Introduces a `rebuild` mode which does not rerun `cmake` in `build_pytorch_libs.sh`.
*Note: `rebuild` should only be used if you dont add / remove files to the build, as `cmake` is not rerun*
Current no-op rebuild speedup:
- 1m 15s -> 20s
There are some lingering bugs. No-op rebuilds rerun `cmake` for two rebuilds (likely that cmake logic is dependent on the install folder, hence kicking off rebuild).
So what you see
```
python setup.py rebuild develop # first time - ~5 mins
python setup.py rebuild develop # second time - ~3 mins
python setup.py rebuild develop # third time - ~2 mins
python setup.py rebuild develop # fourth time - ~20 seconds
python setup.py rebuild develop # fifth time - ~20 seconds
```

* hcc brings two important compiler fixes (fixes hundreds of unit tests)
* HIP brings a smart dispatcher that allows us to avoid a lot of static_casts (we haven't yet removed the automatic static_casts but this catches some occurrences the script did not catch)
* mark 5 unit tests skipping that have regressed w/ the new hcc (we don't know yet what is at fault)
* optimize bitonic sort - the comparator is always an empty struct - therefore passing it by value saves at least 3 bytes. It also removes an ambiguity around passing references to `__global__` functions

Summary:
This is the last step in the custom operator implementation: providing a way to build from C++ and Python. For this I:
1. Created a `FindTorch.cmake` taken largely from ebetica with a CMake function to easily create simple custom op libraries
2. Created a ` torch/op.h` header for easy inclusion of necessary headers,
3. Created a test directory `pytorch/test/custom_operator` which includes the basic setup for a custom op.
1. It defines an op in `op.{h,cpp}`
2. Registers it with the JIT using `RegisterOperators`
3. Builds it into a shared library via a `CMakeLists.txt`
4. Binds it into Python using a `setup.py`. This step makes use of our C++ extension setup that we already have. No work, yey!
The pure C++ and the Python builds are separate and not coupled in any way.

Summary:
```
This removes PyObjectFinalizer. We were seeing SIGSEGV at exit in some
programs that use multiprocessing. The backtrace pointed to
StorageRef.__del__ being called from subtype_dealloc. My guess is that
the Python interpreter was shutdown before all C++ Storage objects were
deallocated. Deallocating the C++ Storage called the finalizer which
called back into Python after it was no longer safe to do so.
This avoids a callback from C++ into Python during Storage finalization.
Instead, dead Storage objects (expired weak references) are collected
periodically when shared_cache exceeds a limit. The limit is scaled with
2x the number of live references, which places an upper bound on the
amount of extra memory held by dead Storage objects. In practice, this
should be very small.

Summary:
Prior to this diff, there have been two ways of compiling the bulk of the torch codebase. There was no interaction between them - you had to pick one or the other.
1) with setup.py. This method
- used the setuptools C extension functionality
- worked on all platforms
- did not build test_jit/test_api binaries
- did not include the C++ api
- always included python functionality
- produced _C.so
2) with cpp_build. This method
- used CMake
- did not support Windows or ROCM
- was capable of building the test binaries
- included the C++ api
- did not build the python functionality
- produced libtorch.so
This diff combines the two.
1) cpp_build/CMakeLists.txt has become torch/CMakeLists.txt. This build
- is CMake-based
- works on all platforms
- builds the test binaries
- includes the C++ api
- does not include the python functionality
- produces libtorch.so
2) the setup.py build
- compiles the python functionality
- calls into the CMake build to build libtorch.so
- produces _C.so, which has a dependency on libtorch.so
In terms of code changes, this mostly means extending the cmake build to support the full variety of environments and platforms. There are also a small number of changes related to the fact that there are now two shared objects - in particular, windows requires annotating some symbols with dllimport/dllexport, and doesn't allow exposing thread_local globals directly.

Summary:
This is a series of two commits that should probably be read separately. They are stacked on top of #9018 since the second commit requires it for correctness.
Commit 1
=======
This commit is the first in a series that will clean up how we handle declaring operators and intrinsics in the JIT to make it more modular and readable. This introduces readable declarations that can be used to register operators and switches gen_jit_dispatch to generate this schema. A follow up PR will remove the dispatch keys like "add-3" and resolve ops directly based on the registered schema, further simplifying the generation process.
* Switches schema over to parsed declarations, in the future this will allow something like:
```
registry.register_intrinsic("foo(Tensor a, Tensor b) -> Tensor", [](Stack& stack) {
...
})
```
This will allow the scalable registration of intrinsics for lists, tuples, and other ops, as long as meta-data for these ops (e.g. derivatives and size propagation routines).
The declarations resemble those used by PythonArgParser but have been singificantly cleaned up to minimize the number of types that can appear in the declaration. We should strive to get the other parts of PyTorch switched over to this restricted declaration set when possible, but it is too much to do in a single PR. My hope is that eventually we will use a very similar language to describe declarations in C10, and this can serve as a guide for that.
Parsing is done using the script lexer, so it is very robust to whitespace and extensible for future types.
This removes the other way we encoded schema, and makes it easier to see what schema are registered.
Current generated declarations: https://gist.github.com/zdevito/a96a17766fb3a098d69a91ee00abaaf6
* Switches how we handle attempting to use an integer in the place of a fixed-sized int list, such as in conv (e.g. 'int[3] stride=1'). Now that we can statically distinguish between int and Tensor, we handle the expansion as an implicit conversion in the compiler. This allows us to simplify the interpreter since it no longer needs to handle the conversion itself.
* Schema declarations have been changed so that they match the type system in the IR exactly. In particular, attribute_info which was used by liftConstantAttributes has been dropped and constant attributes are lifted purely based on the type of the input. Type conversions in compiler have been simplified due to this change.
* Error highlighting in ErrorReport now only reports at most 20 lines of code, to make reading where an error occurred easier.
Commit 2
=======
This commit unifies aten_dispatch and aten_schema into a single Operator object that both contains schema and implementation information. In the future we can use this object to also contain functionality like shape prop and autodiff needed by all operators. Operators are registered globally, and dispatch logic uses the schema information to figure out which variant to use. Descriptor keys, a frequent source of inscrutable debug errors, have been removed.
* Introduce Operator, to replace TensorOp. Unlike TensorOp, we use Operator for all op implementations, including primitives that may occur in the graphs. The only exceptions are ops that are only known to the interpreter like jumps, and GraphExecutors where we need to record additional debug info.
* Adds a global registry for Operator implementations. aten_dispatch.cpp turns into register_aten_ops.cpp, which registers all the Operators for aten with the operator registry. register_prim_ops.cpp now contains the implementations for primitive operators that used to be in the interpreter. This means that it is now safe to use `getOperation(node)` to lookup the true interpreter function for the node, which will simplify const-propagation passes.
* Remove addInterpreterOpHandler in favor of global operator registry.
* Instead of descriptors, we match Node arguments directly against FunctionSchema describing expected inputs in `matchSchema`. `matchSchema` knows how parse both attributes and positional inputs from a node and match it to the appropriate registered operator. Debug error messages when we try to run an invalid operator are significantly improved: they now automatically display the schema for the op with the same name that are registered.
* Merge aten_schema into regsiter_aten_ops. Each Operator takes a string schema which is parsed to determine when to dispatch to that op.
* Cleans up gen_jit_dispatch.py now that we do not need to write out descriptors. In particular, skip_scalar_overloads can be removed since Richard's code sorts declarations to put Tensor, Tensor declarations first.
* remove matchSchemaAndLiftConstantAttributes and use emitBuiltinCall instead to remove code duplication
* refactor stack manipulation functions into a separate header file.

Summary:
The underlying use-case is the file descriptor to storage cache in
torch.multiprocessing.reductions. Previously, this was implemented by wrapping
an existing allocator with a "weak ref" allocator which also knew to null out
the weak reference when the storage died. This is terribly oblique, and
prevents us from refactoring the allocators to get rid of per-storage allocator
state.
So instead of going through this fiasco, we instead directly implement weak
pointers and finalizers in THStorage. Weak pointers to THStorage retain the
THStorage struct, but not the data_ptr. When all strong references die,
data_ptr dies and the finalizers get invoked.
There is one major hazard in this patch, which is what happens if you
repeatedly call _weak_ref on a storage. For cleanliness, we no longer
shove our grubby fingers into the finalizer struct to see if there is already
a Python object for the weak reference and return it; we just create a new one
(no one is checking these Python objects for identity). This means if you
keep calling it, we'll keep piling on finalizers. That's bad! But I am
not going to fix it until it is actually a problem for someone, because
then we need to add another caching layer.

Summary:
With the Cppzation of a few files in `TH`/`THC`, the CPP extensions got broken whenever the user uses feature from `THC` in their files, when pytorch is installed via `python setup.py install`.
This addresses issues such as
```

This commit implements the solution proposed in https://github.com/pytorch/pytorch/issues/8410
to workaround the need to create zero tensors with the same shape as inputs.
It introduces the concept of a LinearBlock which marks places in the code
where we know if all the inputs to the node are zero, then the outputs
to the node are also zero. Autodiff introduces LinearBlocks around
backwards functions, which have this property. specializeUndef then
propagates Undef nodes using this information.
Notes:
* Since we do not always specialize, we have a pass LowerLinearBlocks
that replaces the block with an if statement that dynamically guards
the Undef case.
* We introduce AutogradAdd which is addition that still works when
its inputs might be undefined. In cases where we specialize this will
get removed in favor of a normal add, but there are cases where
gradient graphs do not specialize (e.g. when they are not differentiable,
but a derivative is required) so it is important for this op to be executable.
Addresses #8177

General approach:
- Add NumberType, FloatType, IntType to represent Python numbers, floats and ints.
- Emit these types for python literals
- Change aten_schema such that Scalars are NumberType, int64_t and bool are IntType.
- Emit aten::type_as, prim::NumToTensor, and prim::TensorToNum nodes for tensor-number math. (see examples below)
- Erase NumberType, prim::NumToTensor, and prim::TensorToNum for ONNX export
### Tensor/number math
```
import torch
@torch.jit.script
def fn(x):
return x + 1
```
```
graph(%x : Dynamic) {
%1 : int = prim::Constant[value={1}]()
%2 : Dynamic = prim::NumToTensor(%1)
%3 : Dynamic = aten::type_as(%2, %x)
%4 : Dynamic = aten::add[alpha={1}](%x, %4)
return (%5);
}
```
### Number/Number Math
```
import torch
@torch.jit.script
def fn(zero):
c = 1 + 1
return zero + c
```
```
graph(%zero : Dynamic) {
%1 : int = prim::Constant[value={1}]()
%2 : int = prim::Constant[value={1}]()
%3 : Dynamic = prim::num_to_tensor(%1)
%4 : Dynamic = prim::num_to_tensor(%2)
%5 : Dynamic = aten::add[alpha={1}](%3, %4)
%c : int = prim::TensorToNum(%6) # this is the result of the addition
...
return (%13);
}
```
List of squashed commits:
* Introduce Python Number types
Added: IntType, FloatType, NumberType with
IntType <: NumberType
FloatType <: NumberType
Changed aten_schema so arguments have corresponding types
* Emit a NumberType for python literals.
Also emit a NumberType for Scalar default values.
* Add prim::NumToTensor and prim::TensorToNum
* Add DynamicType -> NumberType implicit cast for bc
* Better ensureTensor error message
* Add ensureTensorOrNumber. Allow passing Number to some functions
Like the range() construct and slices
* Patch IntList to work.
IntList is still a DynamicType in the frontend: a tensor gets built from
a List[int].
Also, IntList[1] is a "union between int and IntList" the way it is
implemented. If the frontend sees an int being passed for an IntList[1]
arg, it converts it to a tensor as well.
* Enforce some order on schemas to avoid overload ambiguity
add(Tensor, Tensor) should appear earlier than add(Tensor, Scalar). This
matches the order in which python_arg_parser parses its arguments.
* Disable std_dim and var_dim tests.
With the new schema information, std(input, keepdim) and std(input, dim)
are ambiguous. This will need to be fixed at a later date.
* Add NumberType erasure pass.
This is used for ONNX export and to ensure that NumberType information
doesn't reach the interpreter
* Add support for mixed tensor/number math ops.
* Tests for new functionality.
Includes:
- Tensor/number math
- number/number math
- EraseNumberTypes pass test
* Patch tests
Update expect tests for:
- decompose_addmm
- loop unrolling tests
Because python numbers are now NumberType, they cannot be returned by
functions anymore. Work around this by using "torch.full", or by adding
a tensor([0]) (taken from FIXME_zerol()). Both approaches are used
because torch.full is more readable, but it is broken in some cases.
* Add erase_number_types to torch/CMakeLists.txt
* Move math back to emitSimpleExpr from emitSugaredExpr
* Remove some dead lines
* Renable some excluded script/trace tests that are fixed.
* Move some tests to expected failure
* Address some comments (more addressing to come)
* Erase relevant aten::type_as nodes in EraseNumberTypes
I also changed it so that EraseNumberTypes is only called for ONNX
export. It is no longer used to prevent
prim::NumToTensor/prim::TensorToNum from reaching shape_analysis or
interpreter.cpp.
shape_analysis infers the type of the output of these nodes to be the
same as their input.
intepreter.cpp treats both of these nodes as no-ops.
* Add reminder to fix std/var
* Call EraseNumberTypes only when exporting a script module
* Update expects after rebase
* [c10d] NCCL python binding and CI test, with bug fixes

- New Jenkins script for building on rocm. For now it is a bit hacked together, but we can improve it once CI is running
- New ROCM docker image for nightly HIP, and also some legacy packages that we need temporarily
- New enabled config py2-clang3.8-rocmnightly-ubuntu16.04-build based off of the existing Caffe2 image (not built yet)
- A big pile of cmake fixes, mostly to turn bits on/off when ROCM build is involved

* Create initial Python bindings for c10d
* clang-format
* Switch link order to include more symbols
* Add bindings and tests for ProcessGroupGloo
* Add broadcast test
* Separate build flag for c10d

* Remove NO_PYTHON for the autograd engine
If there is no python bindings, then a default Engine is constructed
the first time it is requested.
If the python libraries are loaded, then they override the default
accessor and the default engine becomes a python Engine.
Note: it is possible for two engines to be generated if a non-python
one gets created before the python bindings are loaded. This case
is rare, and just results in additional threads being spawned.

* Adding another test to be included with ROCm building.
* Updated the setup_helpers scripts in order to get around linter error
* Fix syntax issue
* Solving lint issue: line too long
Improve script builtin checking using schema
* This add aten_schema.h which provides a barebones amount of type and
argument information about each builtin operator
* emitBuiltinCall is updated to use this information rather than
aten_dispatch to ensure the operator is correct.
* handling of keyword and position arguments now matches python behavior
* There is no longer a requirement that kwargs be constant or that the
attributes of an op must be entirely constant or non-constant
* compiler now constructs a non-attributed version of the op first and
then turns it into the constant-attribute version if all attributes
are constants.
* default arguments for builtins now work
* SugaredValue::call and similar functions now have SourceRange information
for their arguments so that error reporting is more accurate
Notes:
* This does not try to merge the builtin checking with python arg parser.
Given that we will eventually have C10 schema which will replace aten_schema,
we will eventually have a C++ description of the schema and working of that
description directly will be the easiest form to understand.
* python function calls and script method calls do not support keyword arguments yet.
When we add this support we should refactor the handling in tryEmitSchema
that resolves keywords into a common function.
* default arguments work
* keyword arguments to builtins work (still need to extend to calling python and other script methods)
* much better error reporting for incorrect builtins
Lift any constants to attributes on nodes when possible
* Schema is usable internally in the compiler as
the function signatures of script functions as well as for builtin
operators.
* Adds a List[T] class to better represent the arguments to cat/stack
as a type rather than with custom checking.
* Support kwargs for calls of script methods
A future commit will be needed to add support for:
* calls to script _functions_ which are currently are GraphExecutors without schema info.
* kwargs to python functions, which will require refactoring python op
When tracing we record expand nodes. This is useful in some cases because
it makes it clear a broadcast happened. However, in future runs
the broadcast may be different or not needed. This change adds an
attribute to expand to track if it was implicitly added. This
takes the form of an unused input to expand with a default value.
The execution engine then removes implicit expands before execution.
Note that shape_analysis will re-add expands when it can prove by
shape analysis that they will exist and this is useful for the fuser,
so this change should not affect fusion passes.
* Split libATen.so into libATen_cpu.so and libATen_cuda.so
Previously, ATen could be built with either CPU-only support, or
CPU/CUDA support, but only via a compile-time flag, requiring
two separate builds. This means that if you have a program which
indirectly uses a CPU-only build of ATen, and a CPU/CUDA-build of
ATen, you're gonna have a bad time. And you might want a CPU-only
build of ATen, because it is 15M (versus the 300M of a CUDA build).
This commit splits libATen.so into two libraries, CPU/CUDA, so
that it's not necessary to do a full rebuild to get CPU-only
support; instead, if you link against libATen_cpu.so only, you
are CPU-only; if you additionally link/dlopen libATen_cuda.so,
this enables CUDA support. This brings ATen's dynamic library
structure more similar to Caffe2's. libATen.so is no more
(this is BC BREAKING)
The general principle for how this works is that we introduce
a *hooks* interface, which introduces a dynamic dispatch indirection
between a call site and implementation site of CUDA functionality,
mediated by a static initialization registry. This means that we can continue
to, for example, lazily initialize CUDA from Context (a core, CPU class) without
having a direct dependency on the CUDA bits. Instead, we look up
in the registry if, e.g., CUDA hooks have been loaded (this loading
process happens at static initialization time), and if they
have been we dynamic dispatch to this class. We similarly use
the hooks interface to handle Variable registration.
We introduce a new invariant: if the backend of a type has not
been initialized (e.g., it's library has not been dlopened; for
CUDA, this also includes CUDA initialization), then the Type
pointers in the context registry are NULL. If you access the
registry directly you must maintain this invariant.
There are a few potholes along the way. I document them here:
- Previously, PyTorch maintained a separate registry for variable
types, because no provision for them was made in the Context's
type_registry. Now that we have the hooks mechanism, we can easily
have PyTorch register variables in the main registry. The code
has been refactored accordingly.
- There is a subtle ordering issue between Variable and CUDA.
We permit libATen_cuda.so and PyTorch to be loaded in either
order (in practice, CUDA is always loaded "after" PyTorch, because
it is lazily initialized.) This means that, when CUDA types are
loaded, we must subsequently also initialize their Variable equivalents.
Appropriate hooks were added to VariableHooks to make this possible;
similarly, getVariableHooks() is not referentially transparent, and
will change behavior after Variables are loaded. (This is different
to CUDAHooks, which is "burned in" after you try to initialize CUDA.)
- The cmake is adjusted to separate dependencies into either CPU
or CUDA dependencies. The generator scripts are adjusted to either
generate a file as a CUDA (cuda_file_manager) or CPU file (file_manager).
- I changed all native functions which were CUDA-only (the cudnn functions)
to have dispatches for CUDA only (making it permissible to not specify
all dispatch options.) This uncovered a bug in how we were handling
native functions which dispatch on a Type argument; I introduced a new
self_ty keyword to handle this case. I'm not 100% happy about it
but it fixed my problem.
This also exposed the fact that set_history incompletely handles
heterogenous return tuples combining Tensor and TensorList. I
swapped this codegen to use flatten() (at the possible cost of
a slight perf regression, since we're allocating another vector now
in this code path).
- thc_state is no longer a public member of Context; use getTHCState() instead
- This PR comes with Registry from Caffe2, for handling static initialization.
I needed to make a bunch of fixes to Registry to make it more portable
- No more ##__VA_ARGS__ token pasting; instead, it is mandatory to pass at
least one argument to the var-args. CUDAHooks and VariableHooks pass a nullary
struct CUDAHooksArgs/VariableHooksArgs to solve the problem. We must get rid of
token pasting because it does not work with MSVC.
- It seems MSVC is not willing to generate code for constructors of template
classes at use sites which cross DLL boundaries. So we explicitly instantiate
the class to get around the problem. This involved tweaks to the boilerplate
generating macros, and also required us to shuffle around namespaces a bit,
because you can't specialize a template unless you are in the same namespace as
the template.
- Insertion of AT_API to appropriate places where the registry must be exported
- We have a general problem which is that on recent Ubuntu distributions,
--as-needed is enabled for shared libraries, which is (cc @apaszke who was
worrying about this in #7160 see also #7160 (comment)). For now, I've hacked
this up in the PR to pass -Wl,--no-as-needed to all of the spots necessary to
make CI work, but a more sustainable solution is to attempt to dlopen
libATen_cuda.so when CUDA functionality is requested.
- The JIT tests somehow manage to try to touch CUDA without loading libATen_cuda.so. So
we pass -Wl,--no-as-needed when linking libATen_cuda.so to _C.so
- There is a very subtle linking issue with lapack, which is solved by making sure libATen_cuda.so links against LAPACK. There's a comment in aten/src/ATen/CMakeLists.txt about htis as well as a follow up bug at #7353
- autogradpp used AT_CUDA_ENABLED directly. We've expunged these uses and added
a few more things to CUDAHooks (getNumGPUs)
- Added manualSeedAll to Generator so that we can invoke it polymorphically (it
only does something different for CUDAGenerator)
- There's a new cuda/CUDAConfig.h header for CUDA-only ifdef macros (AT_CUDNN_ENABLED, most prominently)
- CUDAHooks/VariableHooks structs live in at namespace because Registry's
namespace support is not good enough to handle it otherwise (see Registry
changes above)
- There's some modest moving around of native functions in ReduceOps and
UnaryOps to get the CUDA-only function implementations into separate files, so
they are only compiled into libATen_cuda.so. sspaddmm needed a separate CUDA
function due to object linkage boundaries.
- Some direct uses of native functions in CUDA code has to go away, since these
functions are not exported, so you have to go through the dispatcher
(at::native::empty_like to at::empty_like)
- Code in THC/THCS/THCUNN now properly use THC_API macro instead of TH_API
(which matters now that TH and THC are not in the same library)
- Added code debt in torch/_thnn/utils.py and other THNN parsing code to handle
both TH_API and THC_API
- TensorUtils.h is now properly exported with AT_API
- Dead uses of TH_EXPORTS and co expunged; we now use ATen_cpu_exports and
ATen_cuda_exports (new, in ATenCUDAGeneral.h) consistently
- Fix some incorrect type annotations on _cudnn_rnn_backward, where we didn't
declare a type as possibly undefined when we should have. We didn't catch this
previously because optional annotations are not tested on "pass-through" native
ATen ops (which don't have dispatch). Upstream issue at #7316
- There's a new cmake macro aten_compile_options for applying all of our
per-target compile time options. We use this on the cpu and cuda libraries.
- test/test_cpp_extensions.py can be run directly by invoking in Python,
assuming you've setup your PYTHONPATH setup correctly
- type_from_string does some new funny business to only query for all valid CUDA
types (which causes CUDA initialization) when we see "torch.cuda." in the
requested string

* Allow tuples to be re-assigned
This commit improves our support of tuples by making them more first-class.
In particular, it allows tuples to be re-assigned across loops and ifs.
It does this by making them first-class values in the Graph IR, and then
removing the tuples in a LowerTuples pass.
An alternative approach would have added more support for desugaring tuples
in the Environment object as they were emitted. Instead,
the current approach was chosen anticipating a future when tuples are
fully supported (including the interpreter). In that future, the current
code can be completly reused with the LowerTuples pass just becoming
a optimization that removes unneeded tuple allocations.

Previously, tensors only had a 'get_device' method which would throw an exception on a CPU tensor. This made it necessary to if/else code that
was meant to be device agnostic.
This PR implements the following:
1) Adds a 'device' property to all tensors that returns a string representation of the device for all tensors.
For cpu tensors this is 'cpu'. For cuda tensors this is 'cuda:X', where X is the cuda device ordinal.
2) Adds a DeviceSpec class. This is just a helper class for separating device_type and device_index specification and to allow partial specification.
For example, you can call DeviceSpec('cuda'), DeviceSpec('cuda:0'), DeviceSpec('cuda', 1).
Also has backwards compatibility support for specifying integers, which are treated as cuda devices.
DeviceSpecs have the following properties:
a) device_type: string representation of the device type (i.e. 'cpu' or 'cuda')
b) device_index: integer for the device index (None if not specified)
c) cuda_device_index: for backwards compatibility; behaves roughly like `get_device` did previously. I.e. if a function previously took integers for cuda devices,
it can now take DeviceSpecs (or strings), and can maintain the old functionality by calling `old_index = DeviceSpec(old).cuda_device_index`.
3) tensor methods and torch. functions that took integer devices can now take integers, strings, or DeviceSpecs. For example:
torch.randn((2,3), dtype=torch.cuda.float32, device='cuda:1')
TODO in future PRs:
A) Split out cuda from dtype so you don't need to overspecify cuda-ness
B) We currently only support strings/DeviceSpecs in tensor methods and torch. functions. We should have equivalents torch.cuda.device(...), torch.cuda.device_of, etc.

* Py_RETURN_NOTIMPLEMENTED doesn't exist in python2.
This changes type(tensor) to return `torch.Tensor` instead of
`torch.autograd.Variable`.
This requires a few implementation changes:
- torch.Tensor is now a regular Python class instead of a
pseudo-factory like torch.FloatTensor/torch.DoubleTensor
- torch.autograd.Variable is just a shell with a __new__ function.
Since no instanes are constructed it doesn't have any methods.
- Adds torch.get_default_dtype() since torch.Tensor.dtype returns
<attribute 'dtype' of 'torch._C._TensorBase' objects>
* Introduce torch.layout and split layout from dtypes.
Tensors (and tensor types) now have a 'layout' attribute that returns either 'torch.strided' or 'torch.sparse_coo'.
Previously, dtypes were 1-to-1 with ATen types/PyTensorTypes; the impetus behind this decision was to make things easy in the common case
(i.e. specifying a type in a factory function). But this doesn't really follow for sparity, which isn't a common case.
It also doesn't properly represent the concept or a dtype, which in numpy are proper scalar types (i.e. roughly the type returned from indexing the
last dimension of an n-d array). But this should be the same whether or not the tensor is represented via strides, sparsity, etc.
This is accomplished by:
1) having the dtype of tensor return the (device-type, scalar-type) combination, i.e. torch.cuda.float32, so both
torch.cuda.FloatTensor and torch.cuda.sparse.FloatTensor have the same dtype
2) Adding a layout parameter to python functions, where the combination of (dtype, layout) maps to an ATen type that is used for dispatch.

* Use THP_API instead of THP_CLASS(new)
- gloo, pybind11, nanopb and nccl now live in third_party.
- ATen builds in aten/build rather than torch/lib/build/aten
- A bit of faffing about in the scripts was necessary, because they used to assume that everything lived in the same directory. Now you are expected to cd into the correct directory before calling one of the build functions. The actual builder script lives in tools
- Lint now just unconditionally ignores third_party, rather than enumerating folders explicitly
* Moved torch headers copy to build_deps
PR #5706 initially moved headers under build_ext to fix bdist_wheel and
build develop. This broke install and #5755 moved them back to install
which broke bdist_wheel and build develop. Looks like build_ext is called
from install after it already tried to copy the headers to the python install
dir and the headers were not installed correctly. Using build_deps works
correct with all setup.py install, bdist_wheel and build develop.
* Comment about the auto-generated files
Added comment that the current solution will not include auto-generated
files which may be a problem if somebody needs to use them
* Add torch.sparse_coo_tensor factory.
Notes:
1) I didn't add Tensor.new_sparse_coo_tensor; it didn't seem particularly useful, but it's easy to add
2) This doesn't do the type inference, i.e. torch.sparse_coo_tensor(indices=LongTensor, values=IntTensor)
will return a sparse tensor corresponding to the default type rather than a sparse IntTensor. We can add
type inference later when we add it to other factories.
* Fix merge.
* Use type_conversion function from python_variable_methods.
#5481 was reverted due to a strange test bug. This PR attempts to fix that.
This diff adds vectorization to ATen. It uses intel intrinsics to build a general vec256 class, that represents types of 256bit width. These can then be treated like regular variables. Using those it implements torch.sum() for the contiguous case. It uses Intel TBB for multithreading, which allows workstealing and chunks the reduction operations based on a experimentally chosen value (_THRESHOLD). It uses cpuinfo to pick the right code depending on the host's capabilities.
The kernels are implemented under native/cpu. Each .cpp file is compiled with -avx, -avx2 and no additional flags. A macro is used to append AVX, AVX2 or NONE to the function name. The header then needs to define the functions three times, one for each capability. This could be improved by either changing the cmake file a bit or possibly generating source code using a Python script etc.
For the non-contiguous case this defaults to the current implementation within TH. For CUDA is entirely defaults to the implementation within THC.
There probably needs to be a bit of a debate around the design decisions here, the additional dependencies, parallelization strategy, clarity, etc. The numerical results also diverge from numpy with larger tensors, which is expected since we're summing, for example, 8 numbers and then adding the result to the running sum, instead of each number one by one. But there might be something to be said about accumulating into a double for floats or the degree of divergence, the behavior with respect to CUDA, etc.
I wrote a [small Python script]( https://github.com/cpuhrsch/benchmark/blob/sumall/benchmarks/sum_bench.py) to compare the results with numpy numerically as well as on timing. I ran this script to create timings both on master and this branch.
Here is the command for 1 core
`OMP_NUM_THREAD=1 taskset -c 0 python sum_bench.py --enable_numpy 200`
Here is the command for all cores
`python sum_bench.py --enable_numpy 200`
Here are the results of each:
[Master, 1 core](https://paste.fedoraproject.org/paste/Nho9JzHpPVK9av8a6mByjQ)
[This branch, 1 core](https://paste.fedoraproject.org/paste/6xLHkYvcVJx9z~5MoHxN4w)
[Master, all cores](https://paste.fedoraproject.org/paste/5l3V1d5zGqvJcMXIUteMRw)
[This branch, all cores](https://paste.fedoraproject.org/paste/J4RuDU-0Drz0aZwtphQwEA)
To test the command is
`python sum_bench.py --test 200`
[This branch, test results](https://paste.fedoraproject.org/paste/kTEoUC~oWgXA6XWMAfNfNw)
For this test we look at the average absolute value of the differences. This does not take into account the relative magnitude of the numbers. The numbers are sampled from a standard normal distribution.
In terms of performance this diff should bring PyTorch on par with Numpy and usually exceed it by 1.5 to 2x.

Add script::Module C++ class to represent script modules
switch AST -> IR conversion to work on Modules/Methods rather than raw graphs
function-only AST -> IR conversion is just a simplified case where there is
only one module with a single method and no parameters.
introduce SugaredValue in compiler.h to represent values in scope in a script
function that are not first-class and that get desugared. This is used to
represent the module's self parameter, as well as python function calls,
and method calls on tensor
provide a Python ScriptModule that provides a nice API on top of script::Module
allowing for the definition of script modules with methods, parameters,
and submodules
Not in this PR but intended for the future:
ScriptModule actually subclasses nn.Module, with most methods implemented
Unification of tracedmodule and script module functionality into one container class.
Detailed changelog:
* Switch compiler over to using Module, but don't
use them yet.
* Remove intermediate attribute encoding in compiler
* Create SugaredValue object to handle resolution
of compiled module.
* switch to_ir to modules, implement Select
* hacky python wrappers
* Private ScriptModule
* Add `define` to script module
* Attributes use TK_LIST_LITERAL
this anticipates adding a real list literal expression to the language.
* Add a metaclass to make sure script stubs are registered
* Add a test
* Doc createResolutionCallback
* Docs and minor editing
* Address PR comments
* Document
* Fix unicode issue
The header files needed for the C++ extensions were copied to

This deletes most of the dead Tensor code paths, including the TensorMethods cwrap and generic/Tensor.cpp.
This also moves the THNN.cwrap/.cpp generation to generate_code which can use ninja if installed.
This replaces the torch.Tensor constructors with factories that produce
Variables. Similarly, functions on the torch module (e.g. torch.randn)
now return Variables.
To keep the PR to a reasonable size, I've left most of the unused tensor
code. Subsequent PRs will remove the dead code, clean-up calls to
torch.autograd.Variable, and rename Variable to Tensor everywhere.
There are some breaking changes because Variable and Tensors had
slightly different semantics. There's a list of those changes here:

* Various dtype improvements.
1) Add dtypes to the new data-based constructors: Variable.new_tensor and torch.autograd.variable.
2) In the python signatures, use Type instead of Dtype to match the C++ signatures; the error messages still print as dtype.
3) Handle / add a better error message when a dtype is used when ATen was not compiled with that type (e.g. cuda types).
4) Move cuda_lazy_init to its own file.
A later commit will add support to the legacy constructors as well.

* Add numpy-style dtypes to Variable factories.
1) Add numpy-style dtypes corresponding to torch tensor types. These are:
torch.float16, torch.float32, torch.float64, torch.uint8, torch.int8, torch.int16, torch.int32, torch.int64
as well as torch.cuda, torch.sparse, and torch.cuda.sparse equivalents.
2) Adds "legacy" names for the above dtypes that correspond more closely to existing tensor names. These are:
torch.half, torch.float, torch.double, torch.short, torch.int, torch.long.
torch.byte and torch.char don't exist because they either don't match numpy semantics or differ on different architectures.
3) Adds a "dtype" parameter to Variable factories (e.g. zeros, ones) that allows the user to specify the type without changing the default tensor type.
4) Adds a "dtype" getter to Variables that return the canonical dtype from 1)
This PR is missing the following useful features that should be added in the future:
A) We only add the "dtype" parameter to auto-generated factories; hand-written factories like in tensor_new.cpp don't support this yet.
B) We don't allow type conversions to use dtypes; that should be added to type(param) or a new function.
C) We don't yet have a "device" parameter for these factories; right now, they will only create Variables on the default device.
* backend_to_string can be private.
* Define python binding argument indexes in a more simple way.
* add all_declared_types, still need to hook it up to THPDType.
* Fix all_declared_types for missing types (it's Sparse + Half).
* Ensure cuda dtypes are created even if compiled with NO_CUDA=1.
* Fix case where dtype is provided but dispatch is via namespace.
This happens in ones_like, empty_like, randn_like.
There is some question if we should do:
1) at::ones_like(tensor).toType(dtype)
2) at::ones_like(tensor.toType(dtype))
I did the former because this matches with the numpy documentation, i.e.:
"Overrides the data type of the result." and it's easier to implement.
Note that the above causes an extra copy, either of the input or output.
Here's a better implementation:
1) Make zeros_like, ones_like native functions that take an optional type (named dtype?).
2) Match the type argument with the dtype, so we don't have two different parameters.
3) Call at::zeros_like(input, type) -> at::native::zeros_like(input, type) -> type.zeros(input.sizes())
* Don't return from maybe_initialize_cuda.
* Don't leak DType name.
* Address cpp review comments.
* Share code between sparse and non-sparse test_dtypes.
* Rewrite _like functions as native function with explicit type parameter.
* Use type 'Type' instead of 'dtype' for consistency.
* Address review comments.
* Handle arg_idx when there is requires_grad but no dtype in python_binding_arguments.

* Remove SavedVariable destructor and construct members in init list

This adds the initial implementation of graph executor for the new JIT design. It includes a few python tests ensuring that nograd, backward, and double-backward cases work for simple examples and some corner cases. More work needs to be done to performance optimize as there are many extra copies and places where we hold onto variables longer than we should. These are noted in the comments.
