ff3ecfec89 Turn script_type_parser into a class (#18211)
Summary:
Pull Request resolved: https://github.com/pytorch/pytorch/pull/18211
ghimport-source-id: 73b81e9ec631937b14db1da10991831788a6894b

Stack from [ghstack](https://github.com/ezyang/ghstack):
* #18296 [jit] Add namespacing for ScriptClasses
* #18284 [jit] make test module hook use save/load
* **#18211 [jit] Turn script_type_parser into a class**
* #18148 [jit] python interop for script classes

If we are namespacing classes, the type parser will need to carry around
some state about which namespaces to look in. This PR just wraps it in a
class in preparation.

Also, subscriptToType can no longer be static, since parseTypeFromExpr
may give different results depending on the namespaces available, so
it's been made a regular function instead of a static map lookup.

be364ac8d7 Specify overload name in function schema (#18037)
Summary:
Pull Request resolved: https://github.com/pytorch/pytorch/pull/18037

The FunctionSchema can now store an overload name and the parser knows how to parse it. Specify like this:

    my_func.overload1(arg1: Tensor) -> Tensor
    my_func.overload2(arg1: Tensor, arg2: Tensor) -> Tensor

Summary:
Stack:
      **#17856 [jit] support serialization of classes**  [💛](https://our.intern.facebook.com/intern/diff/D14402599/)

Add support for saving/loading TorchScript modules that depend on user-defned classes.

We track class dependencies the same we track tensor constants, then write them
all out such that we can just compile them in order before compiling the module
hierarchy.

2cdbb140e6 user defined types (#17314)
Summary:
First pass at user defined types. The following is contained in this PR:
- `UserType` type, which contains a reference to a module with all methods for the type, and a separate namespace for data attributes (map of name -> TypePtr).
- `UserTypeRegistry`, similar to the operator registry
- `UserObject` which is the runtime representation of the user type (just a map of names -> IValues)
- `UserTypeValue` SugaredValue, to manage getattr and setattr while generating IR, plus compiler.cpp changes to make that work.
- Frontend changes to get `torch.jit.script` to work as a class decorator
- `ClassDef` node in our AST.
- primitive ops for object creation, setattr, and getattr, plus alias analysis changes to make mutation safe.

Things that definitely need to get done:
- Import/export, python_print support
- String frontend doesn't understand class definitions yet
- Python interop (using a user-defined type outside TorchScript) is completely broken
- Static methods (without `self`) don't work

Things that are nice but not essential:
- Method definition shouldn't matter (right now you can only reference a method that's already been defined)
- Class definitions can only contain defs, no other expressions are supported.

Things I definitely won't do initially:
- Polymorphism/inheritance

2370c989d8 Add LSTM to standard library (#15744)
Summary:
**WIP**

Attempt 2 at #14831

This adds `nn.LSTM` to the jit standard library. Necessary changes to the module itself are detailed in comments. The main limitation is the lack of a true `PackedSequence`, instead this PR uses an ordinary `tuple` to stand in for `PackedSequence`.

Most of the new code in `rnn.py` is copied to `nn.LSTM` from `nn.RNNBase` to specialize it for LSTM since `hx` is a `Tuple[Tensor, Tensor]` (rather than just a `Tensor` as in the other RNN modules) for LSTM.

As a hack it adds an internal annotation `@_parameter_list` to mark that a function returns all the parameters of a module. The weights for `RNN` modules are passed to the corresponding op as a `List[Tensor]`. In Python this has to be gathered dynamically since Parameters could be moved from CPU to GPU or be deleted and replaced (i.e. if someone calls `weight_norm` on their module, #15766), but in the JIT parameter lists are immutable, hence a builtin to handle this differently in Python/JIT.

ac00e85e36 Remove undefined tensor in jit script (#16379)
Summary:
This PR is a follow up of #15460, it did the following things:

* remove the undefined tensor semantic in jit script/tracing mode
* change ATen/JIT schema for at::index and other index related ops with `Tensor?[]` to align with what at::index is really doing and to adopt `optional[tensor]` in JIT
* change python_print to correctly print the exported script
* register both TensorList and ListOfOptionalTensor in JIT ATen ops to support both
* Backward compatibility for `torch.jit.annotate(Tensor, None)`

List of follow ups:

* remove the undefined tensor semantic in jit autograd, autodiff and grad_of
* remove prim::Undefined fully

d4f6befc93 Add implicit optional unwrapping (#15587)
Summary:
Add support for type inference for optional type refinement.

If a conditional is of the form "x is None" or "x is not None", or is a boolean expression containing multiple none checks, the proper type refinements are inserted in each branch.

For example:
if optional_tensor is not None and len(optional_tensor) < 2:
	# optional_tensor is a Tensor

if optional_tensor1 is not None and optional_tensor2 is not None:
	# both optional_tensor1 and optional_tensor2 are Tensors

TODO:

- not run an op for unchecked unwrap optional in the interpreter

- potentially refine types to prim::None (omitted for now to simply things & because it's not an actual use cause).

1a2ec10bd4 Support enough of closures to write autograd functions (#15411)
Summary:
This PR adds enough of the infra for supporting closures (inner script functions) in order to allow us to expression symbolic gradients using them. We do not actually ever run graphs that contain these closures. The symbolic_script infrastructure just extracts them out of the original forward graph and turns them into discrete forward/backward pairs. This cuts down on the type annotations necessary to write forward/backward pairs and aligns closely with the "differentiator" function approach to expression reverse-mode AD.

Example:

This code:
```
import torch

r = torch.jit.CompilationUnit(
'''
def mul_forward(self, other):
    def backward(grad_output):
        grad_self = (grad_output * other).sum_to_size(self.size())
        grad_other = (grad_output * self).sum_to_size(other.size())
        return grad_self, grad_other
    return self * other, backward
''')

print(r.module.code)
```

Will produce this graph (pretty printed for clarity):

```
def mul_forward(self,
    self: Tensor,
    other: Tensor) -> Tuple[Tensor, Tuple[None, Tuple[Tensor, Tensor]]]:
  backward = (self.__lambda, (other, self))
  return (torch.mul(self, other), backward)

def __lambda(self,
    context: Tuple[Tensor, Tensor],
    grad_output: Tensor) -> Tuple[Tensor, Tensor]:
  other, self, = context
  grad_self = torch.sum_to_size(torch.mul(grad_output, other), torch.size(self))
  grad_other = torch.sum_to_size(torch.mul(grad_output, self), torch.size(other))
  return (grad_self, grad_other)
```

symbolic_script will then do some modifications to remove the unsuppored prim::Function node, yielding:

```
def mul_forward(self,
    self: Tensor,
    other: Tensor) -> Tuple[Tensor, Tuple[None, Tuple[Tensor, Tensor]]]:
  return (torch.mul(self, other), (other, self))

def backward(self,
    context: Tuple[Tensor, Tensor],
    grad_output: Tensor) -> Tuple[Tensor, Tensor]:
  other, self, = context
  grad_self = torch.sum_to_size(torch.mul(grad_output, other), torch.size(self))
  grad_other = torch.sum_to_size(torch.mul(grad_output, self), torch.size(other))
  return (grad_self, grad_other)
```

0368054a6d Split up compiler.cpp (#15355)
Summary:
This separates the different parts of compiler.cpp to make their relationship more clear. In particular it adds:

* sugared_value.{h,cpp} - all the public SugaredValues that the compiler defines and a few that were inside compiler.cpp
* type_parser.{h, cpp} - Turns TreeRef's defining types into TypePtr
* schema_matching.{h, cpp} - infrastructure for matching arguments against overloaded schema and emitting builtin operators with a particular schema.
Retains:
* compiler.{h, cpp} - now responsible simply for the `defineMethodsInModule` infra structure.

Some utility functions like inlineCallTo have moved to ir.h.

Only thing that is not a move is some changes in module.h/cpp that remove multiple returns from `Method::emit_call_to`.

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.

aecab53778 Support torch.tensor in script (#14913)
Summary:
Adding support for torch.tensor in script.

The input list is typed as t[], because it can be arbitrarily nested. I added a check a compile time check  that the inner type of the list is a bool, float, or int.

Also adds specialization for Boolean Lists, which already existed at the ivalue level but had not been added to the compiler yet

48a361cc62 Clean up casting ops (#14947)
Summary:
This removes FloatToInt style names replacing it with just the destination
name (e.g. FloatToInt -> Float). This makes it more consistent with the
syntax and makes it easier to add type conversions (just add a new
prim::Int op, for instance).

None of these ops get serialized so this should not effect loading of
old models.

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)

78d594f46c Implement Device as a type in the script (#14666)
Summary:
[ note:  stacked on expect files changes, will unstack once they land ]
This adds DeviceObjType (cannot use DeviceType it is already an enum)
to the type hierarchy and an isDevice/toDevice pair to IValue.
Previous hacks which used an int[] to represent Device are removed
and at::Device is used instead.

Note: the behavior or .to is only a subset of python, we need to
fix the aten op so that it accepts Option[Device] and Optional[ScalarType].

4b31572375 Meta programming on If Stmt cond to enable conditional emit blocks (#14533)
Summary:
This PR is a part of task to unblock standard library export. Basically we want enable the ability to meta program IF stmt to dynamically emit different branches base on `cond`. This is primarily used to disable certain branch compilation on If, like the below

```python
import torch

class Test(torch.jit.ScriptModule):
  def __init__(self, b = None):
    self.b = b
  def forward(self, input):
    x = input
    if self.b is not None:
      x = self.b(input)

    return x

  Test()(torch.randn(2, 3))
```
This is also the first step for us to bridge the gap between none simple value and any sugared value in JIT.

fd31eae9ad Switch import/export to python printing (#14400)
Summary:
Stacked on https://github.com/pytorch/pytorch/pull/14378, only look at the last commit.

This changes the way methods are defined in TorchScript archives to use
PythonPrint rather than ONNX protobufs.

It also updates torch.proto to directly document the tensor data
structure actually being serialized.

Notes:
* because PythonPrint prints all the methods at once per module, this
  removes MethodDef in favor of a single torchscript_area and a separate
  caffe2_graphs entry. Note that NetDef's already have method names,
  so there is no need or a separate method name entry.
* This switches cpp/pickle area to RecordRef (references to a file in
  the container format) since it is possible the data in these arenas
  may be large and not suited to json ouput.
* Removes 'annotations' -- annotations should be re-added on the first
  commit that actually has a practical use for them. In the current state
  it is unlikely they are representing the right information.
* Some expect files have changed because PythonPrint is preserving more
  debug name information for parameter names.
* MethodEncoder (the ONNX output format) has been deleted. There is still
  some cleanup possible combining EncoderBase and GraphEncode now that there
  is only a single pathway using EncoderBase.
* This incorporates the changes from #14397
  to define TensorDef
