bdc57d3833 Merge ProfiledTensorType and TensorType (#24284)
Summary:
Pull Request resolved: https://github.com/pytorch/pytorch/pull/24284

This PR finishes the unification of all Tensor types into a single object.
ProfiledTensorType is renamed to TensorType and the old TensorType is
deleted.

Notes:
* Fixes bug in merge for VaryingShape by changing its representation to an
 optional list of optional ints.
* Removes ProfiledTensorType::create(type) invocations that can now
  simply be expect calls on tensor type.

c2549cb8d3 Remove DimensionedTensorType (#24077)
Summary:
Pull Request resolved: https://github.com/pytorch/pytorch/pull/24077

This replaces all uses of DimensionedTensorType with ProfiledTensorType.
For places where we propagate shape information, we still follow the
dimension-only propagation rules, meaning that even if full size information
is known on inputs the outputs will only have dimension information.

This fixes several bugs in existing implentations that this change uncovered:
* requires_grad was not propgated correctly across loops
* requires_grad on ProfiledTensorType returned false when requires_grad information
  is unknown but the conservative result is true
* some equality code on ProfiledTensorType contained bugs.

7583519b87 Provide argument in ONNX export to exclude intializers from graph inputs. (#23284)
Summary:
Starting ONNX IR version 4, the initializers in the ONNX graph do not have to be inputs of the graphs. This constraint, which existed in IR version 3 and earlier, was relaxed in IR version 4. This PR provides an API level argument to allow ONNX export with the relaxed constraint of IR version 4, i.e. provides the option to not include initializers as inputs. This allows backends/runtimes to do certain optimizations, such as constant folding, better.

*Edit*: After discussion with houseroad we have the following behavior. For any OperatorExportType, except OperatorExportTypes.ONNX, the current status of export is maintained in this PR by default. However, the user can override it by setting the `keep_initializers_as_inputs` argument to the export API.  But when exporting to ONNX, i.e. OperatorExportType is OperatorExportTypes.ONNX, the current status is changed in that by default the initializers are NOT part of the input. Again, the default can be overridden by setting the `keep_initializers_as_inputs` argument.

ef406ee925 First class modules in the compiler, round 2 (#19167)
Summary:
This PR propagates where we use first-class modules objects into the compiler. This creates a transitionary state where:

* compiler.cpp creates Graphs where `self` is a Module class and attributes/parameters/buffers/submodules are looked up with `prim::GetAttr`
* GraphExecutor still runs "lowered graphs" where the self object has been removed by a compiler pass `lower_first_class_method`.
* Tracing still creates "lowered graphs", and a pass "lift_lowered_method" creates a first-class method graph for things.

* This PR separates out Method and Function. A script::Function is a pure Graph with no `self` bound.  Similar to Python, a script::Method is just a bound `self` and its underlying `script::Function`.
* This PR also separates CompilationUnit from Module. A CompilationUnit is just a list of named script::Functions.  Class's have a CompilationUnit holding the class methods, and Modules also have a CompilationUnit holding their Methods. This avoids the weird circular case Module --has a-> Class -> has a -> Module ...

Details:
* In this transitionary state, we maintain two copies of a Graph, first-class module and lowered. Th first-class one has a self argument that is the module's class type. The lowered one is the lowered graph that uses the initial_ivalues inputs.
* When defining lowered methods using `_defined_lowered` we immediately create the first-class equivalent. The reverse is done lazily, creating lowered_methods on demand from the class.
* The two way conversions will be deleted in a future PR when the executor itself runs first-class objects. However this requires more changes to (1) the traces, (2) the python bindings, and (3) the onnx export pass and would make this PR way to large.

92f70bb639 Split python_ir.h in a more sensible way (#19081)
Summary:
Files included in libtorch do depend on torch/csrc/utils/object_ptr.h, e.g. ir.cpp: https://github.com/pytorch/pytorch/blob/master/torch/csrc/jit/ir.h#L10 (including usage in std::vector that requires destructor for THPPointer)

However, object_ptr.h depends on python stub: https://github.com/pytorch/pytorch/blob/master/torch/csrc/utils/object_ptr.h#L3

Whereas object_ptr.cpp depends full on on python: https://github.com/pytorch/pytorch/blob/master/torch/csrc/utils/object_ptr.cpp#L8

`torch/csrc/utils/object_ptr.cpp` is included only in Python extension target: https://github.com/pytorch/pytorch/blob/master/torch/CMakeLists.txt#L541

The only reason it was working on master is that compiler was aggressive enough in pruning unused inline functions. With a bit of changes in flags, it started breaking (like in kostmo's PR).

This PR splits out python-dependent bits more explicitly by forward declaring THPPointer for real.

e4c9d75008 - refactoring serialization of ONNX initializers to be name-based (#17420)
Summary:
Currently, serialization of model parameters in ONNX export depends on the order in which they are stored in a container (`list` on Python side and `std::vector` on C++ side). This has worked fine till now, but if we need to do any pass on that graph that mutates the parameter list, then strictly order-based serialization may not work.

This PR is the first in a set to bring in more passes (such as constant folding) related to ONNX export. This PR lays the groundwork by moving the serialization in ONNX export from order-based to name based approach, which is more amenable to some of the passes.

houseroad - As discussed this change uses a map for export, and removes the code from `export.cpp` that relies on the order to compute initializer names.

```
torch.jit.script
def test(x, y):
    for i in range(10):
        x += 10
        x.resize_as_([1 for i in int(range(torch.rand())))
    return x

1aa90192ea Make JIT attributes t_ and ts_ store Variable instead of Tensor (#16596)
Summary:
Discussed with zdevito and we want to use Variable (with `set_requires_grad(false)`) instead of Tensor in all parts of JIT, to eliminate the distinction and the conceptual overhead when trying to figure out which one to use.

This also helps with the Variable/Tensor merge work tracked at https://github.com/pytorch/pytorch/issues/13638, which will make common functions (such as `numel()` / `sizes()` / `dim()`) on Variable much faster when finished.

dc84ff1e5a Use a points-to graph for alias analysis (#16386)
Summary:
This PR changes the way we store aliasing information from a "set" approach to a "points-to" analysis. Set-based approaches lose information in ways that make it difficult to do "live" updates to the alias DB as one as mutating the graph.

The tradeoff is that simple queries get more expensive, since they require traversing the points-to graph to answer most questions. In practice, this is unlikely to be that costly since we don't have massive aliasing chains, but we could create an approximation/caching layer if this becomes a problem.

My rough plan is:
1. This PR, switching to a points-to graph
2. Make it "live": analyzing a node should record all the edges the node added, so that we can rollback when the node is destroyed.
3. Reduce wildcard scope: we can make the wildcard a special vertex that points to anything that we're not "sure" about; namely, things that have been put inside lists, or graph inputs.

8710184eea Constant propagation changes (#16244)
Summary:
- remove loop node that is guaranteed not to execute
- remove extra loop outputs that are no longer needed

- if we are inlining an if node, only run constant propagation on the block that will execute

- remove the recurse argument since we only expose the Graph Constant Propagation and it's not used

This also includes  a few extra hooks to python_ir that I think make it a little be easier to test graph conditions from python.

1235aa4fca Expose dim() on type and use it in ONNX symbolics (#15933)
Summary:
While integrating fork/join into production translation, we found that trying to export `transpose()` where the input is of `TensorType` (rather than `CompleteTensorType`) failed. This is not ideal, since `TensorType` still contains the number of dimensions of the tensor, and that's all the `transpose` symbolic needs.

This PR introduces a pybind binding for `dim()` on `TensorType` (and `CompleteTensorType` by inheritance). We now use this in places where it logically makes sense in the symbolics: those symbolics which only require knowledge of the number of dimensions rather than concrete sizes.

7b87ecae37 Move autograd metadata from VariableImpl to TensorImpl (#13827)
Summary:
Changes originally in this PR:
1. Move Variable::Impl data members into TensorImpl as `AutogradMeta` struct
2. Change Variable::Impl functions to use data members in `AutogradMeta` struct
3. Add `shallow_copy_and_detach()` function to each subclass of TensorImpl
4. Do shallow copy when the user calls `make_variable(tensor)` / `make_variable_view(tensor)` / `variable.set_data(tensor)` / `variable.detach()`

Changes moved from https://github.com/pytorch/pytorch/pull/13645:
1. Add a flag to Variable to disallow size/stride/storage_ptr changes from in-place operations such as `resize_` / `resize_as_` / `set_` / `transpose_`, and set this flag to true when people call `tensor.data` in Python.
2. Write text in the docs to actively discourage changing the shape or storage of `tensor_detached` and expecting `tensor` to also be updated.

This is the 1st+2nd PR mentioned in https://github.com/pytorch/pytorch/issues/13638.

f636dc9276 clang format world (#15524)
Summary:
The PR clang-formats everything in `torch/csrc/jit/` and adds it to the pre-commit hook.

Here is a list of non-mechanical changes:
- I went over each file and fixed up whenever I could tell that clang-format was clobbering comment formatting.
- Made the macros in register_prim_ops a little more clang-format friendly by omitting trailing commas
- Refactored autodiff.cpp to use a helper class with explicit state rather than a bunch of capturing lambdas
- Small improvements to the precommit hook clang-format

056cfaf3ff Method returns a single argument (#15289)
Summary:
This PR changes Method (just Method not all graphs) to always have a single
return argument.

This is part 1 in a set of changes that will enable us to have better handling if early return statements.
The simplification that this change provides greatly reduces the work for the next step.

This change makes it so that Method and Python handle multiple returns in the same way:
* 0 - None
* 1 - <single value>
* many - Tuple[...]

The result is that a lot of special-case handling in compiler.cpp and its
bindings can be removed. It also fixes several bugs in return handling,
including one where return values were not always checked against their
attributed values.

Notes:
* inferTypeFrom is renamed to be more accurate and discourage use.
* This has uncovered some bugs in other components, which are noted in
  the diff.

7a61306031 Enable all clang-tidy performance checks (#15198)
Summary:
This PR adds the final set of clang-tidy checks we should add for our codebase: a last set of performance-related checks. Most fixes here are around changing `auto` to `const auto&` in a few places where unnecessary copies were made, and adding `reserve()` calls before loops doing repeated `push_back()`. Also a few cases of calling `std::string::find` with a single-character string literal instead of a single char, which uses a less efficient string search algorithm meant for searching larger substrings.

517c7c9861 Canonicalize all includes in PyTorch. (#14849)
Summary:
Anywhere we used #include "foo.h", we now say #include <foo.h>
Paths are adjusted to be rooted out of aten/src, torch/lib, or
the root level directory.

I modified CMakeLists.txt by hand to remove TH and THC from
the include paths.

I used the following script to do the canonicalization:

```
  import subprocess
  import re
  import os.path

  files = subprocess.check_output(['git', 'ls-files']).decode('utf-8').rstrip().split('\n')
  for fn in files:
      if not any(fn.endswith(suff) for suff in ['.cu', '.cpp', '.in', '.h', '.hpp', '.cu', '.cuh', '.cc']):
          continue
      if not any(fn.startswith(pref) for pref in ["aten/", "torch/"]):
          continue
      with open(fn, 'r') as f:
          c = f.read()
      def fmt(p):
          return "#include <{}>".format(p)
      def repl(m):
          p = m.group(1)
          if p in ["dlfcn.h", "unistd.h", "nvrtc.h", "cuda.h", "cuda_runtime.h", "cstdint", "cudnn.h", "Python.h", "cusparse.h", "cuda_runtime_api.h", "cuda_fp16.h", "cublas_v2.h", "stdint.h", "curand_kernel.h"]:
              return fmt(p)
          if any(p.startswith(pref) for pref in ["torch/csrc", "c10/", "ATen/", "caffe2/", "TH/", "THC/", "Eigen/", "gtest/", "zdl/", "gloo/", "onnx/", "miopen/"]):
              return fmt(p)
          for root in ["aten/src", "torch/lib", ""]:
              for bad_root in [os.path.dirname(fn), "aten/src/TH", "aten/src/THC", "torch/csrc"]:
                  new_p = os.path.relpath(os.path.join(bad_root, p), root)
                  if not new_p.startswith("../") and (os.path.exists(os.path.join(root, new_p)) or os.path.exists(os.path.join(root, new_p + ".in"))):
                      return fmt(new_p)
          print("ERROR: ", fn, p)
          return m.group(0)
      new_c = re.sub(r'#include "([^"]+)"', repl, c)
      if new_c != c:
          print(fn)
          with open(fn, 'w') as f:
              f.write(new_c)
```
