679fc90cdb [ONNX] Support optional type (#68793) (#73284)
Summary:
Pull Request resolved: https://github.com/pytorch/pytorch/pull/73284

Some important ops won't support optional type until opset 16,
so we can't fully test things end-to-end, but I believe this should
be all that's needed. Once ONNX Runtime supports opset 16,
we can do more testing and fix any remaining bugs.

b34b192d6b Reland "Make debug_pkl smaller by only emitting unique traces." (#73368)
Summary:
## Original commit message:
Pull Request resolved: https://github.com/pytorch/pytorch/pull/73368

debug_pkl file inside of pytorch's .pt file consists of a list of SourceRanges. Each SourceRange points to a Source which is a stack track, filename, and start, end numbers. Those are emitted in debug_pkl file as strings.
Since many SourceRange shares the same source, the string for trace can be deduped.
The newer format saves a set of unique traces in a tuple, then each SourceRange will save the offset of it's trace w.r.t. position in that tuple. (i.e. manually applying dictionary compression).
The above helps with smaller file size. On loading, if we copy each trace to Source as string the runtime memory would still blowup.
To mitigate this, we use SourceView directly instead of source which will take the reference of string inside of Deserializer and make that into string_view. This is safe because Deserializer is hold by Unpickler by shared_ptr, and Unpickler is also hold by shared_ptr by another Source object. That Source object will be alive during the model construction.

6694fdaccd Clean up profiling mode and profiling executor strategy (#73875)
Summary:
Pull Request resolved: https://github.com/pytorch/pytorch/pull/73875

Previously we had a few settings:
- getExecutor - which toggled between Profiling Executor and Legacy
- getGraphOptimize - if true, overrides PE/Legacy to run with simple executor (no optimizations)
and then...
- getProfilingMode - which would set PE to 0 specializtions.

The last mode is redundant with getGraphOptimize, we should just remove it and use getGraphOptimize in these cases. It would lead to potentially invalid combinations of logic - what does mean if getProfilingMode is true but getExecutor is set to false ? This would lead to a bug in specialize_autograd_zero in this case, see: https://github.com/pytorch/pytorch/blob/master/torch%2Fcsrc%2Fjit%2Fpasses%2Fspecialize_autogradzero.cpp#L93.

The tests here are failing but get fixed with the PR above it, so i'll squash for landing.

fc2cf3d26f Back out "Revert D34805092: Extend _save_for_mobile and _load_for_mobile to support flatbuffer format; Default format is pickle + Change buck targets to support only pickle and pickle + flatbuffer for migration" (#74594)
Summary:
Pull Request resolved: https://github.com/pytorch/pytorch/pull/74594

Extending `_save_for_mobile` and `_load_for_mobile` to support faltbuffer format with additional optional argument which is set to pick pickle by default.

Adding new binary target with suffix `_pickle_and_flatbuffer` to help migration.

Size test in D34909502 shows the size has regressed by ~40K but after removing pickle and comparing lite_predictors we have ~120K size measure that we will achieve when deprecating pickle and moving to flatbuffer

bbac8c9c48 [ONNX] List of files to consider for mergebot onnx rule (#72297)
Summary:
Based on past PRs, here is an non-exhaustive list of files to consider for extension. The PR is not meant to be final. Based on feedback and discussion, files could be dropped from the list, or PR could be updated to move code around such that extension is no longer needed.

List of files below and description:

* These files are for converting from IR to ONNX proto. These should be used only for ONNX.
```
"torch/csrc/jit/serialization/export.*",
"torch/csrc/jit/serialization/onnx.*",
```

* This file is touched whenever pass signature is updated.
```
"torch/_C/__init__.pyi.in",
```

* These files are touched whenever pass signature is updated. Somehow it's been convention that onnx passes are also added here, but it could be possible to move them. Let me know what you think.
~~"torch/csrc/jit/python/init.cpp",~~
~~"torch/csrc/jit/python/script_init.cpp",~~
Update: Bowen will move onnx passes to files under onnx folder.

* ~~Touched when need new attr::xxx, or onnx::xxx.~~
~~"aten/src/ATen/core/interned_strings.h"~~
Update: Nikita will help separate this file.

e755a4f124 Update the operator version check logic when generating models for testing upgraders (#71894)
Summary:
The model generation script will check the model version, to ensure the developer run the script before they change operator

Previously, the version use the old model version. However, it's hard for developer to know the old version number. In this change, it use the current max operator version to check. It's less strict, but more developer friendly

Summary:
Pull Request resolved: https://github.com/pytorch/pytorch/pull/68691

TraceType is a sharded file, so by only including specific operator
headers, we ensure that changing one (non-method) operator only needs
one shard to be re-compiled.

This also changes all the included autograd and jit headers from
including `ATen/ATen.h` to just including `ATen/core/Tensor.h`.

f510193e22 [jit][edge] Export maybe-used interface methods from modules. (#65966)
Summary:
Pull Request resolved: https://github.com/pytorch/pytorch/pull/65966

ghstack-source-id: 141594521

Support exportation of "interface methods" from submodule to a mobile module. "Interface methods" are defined as methods which might be dynamically called in a module therefore need to be exported anyway, like virtual functions in C++.

Before this change the algorithm of exportation is a simple iteration through all toplevel methods. Now since we have indirect calls, we need to recursively walkthrough the call graph to find all potentially used methods, which means the order we export methods might break in old runtimes, to guarantee forward compatibility we need to export toplevel methods first, then extra methods, in this order toplevel methods will always be found first.

NOTE that interface methods exportations are disabled by default in this diff. We need to call torch._C._enable_mobile_interface_call_export to actaully enable it.

04043d681e [package] fix storage serialization collision (#61806)
Summary:
Pull Request resolved: https://github.com/pytorch/pytorch/pull/61806

Currently, if you do `save_pickle` on a ScriptModule, then `save_pickle`
on a tensor, this would result in a `0.storage` tensor being written
*twice* to the zip archive. This would cause weird bugs on the
serializing side (this presented as a ASAN-detected heap buffer overflow
because we tried to read more memory from a tensor than we actually
had).

Turns out this was because when we did:
```
self.storage_context = self.script_module_serializer.storage_context()
```
it returned a new copy of the storage context, so we weren't actually
assigning unique names to tensors!!

This PR fixes the issue by making `(De)SerializationStorageContext`
non-copyable and fixing up the parts of the bindings that returned by
copy.

4a2e8b53bb [JIT] Add torch._C.ScriptList` (#52832)
Summary:
Pull Request resolved: https://github.com/pytorch/pytorch/pull/52832

**Summary**
This commit adds `torch._C.ScriptList`, a list type that has reference
semantics across the Python/TorchScript boundary. That is, modifications
made in TorchScript to instances of `torch._C.ScriptList`
are visible in Python even when it is not returned from the function.

`torch._C.ScriptList` is implemented using a modified version of pybind's
`stl_bind.h`-style bindings attached to `ScriptList` and `ScriptListIterator`,
wrapper classes around `c10::impl::GenericList` and
`c10::impl::GenericList::iterator`. These bindings allow instances of
`torch._C.ScriptList` to be used as if it were a
regular `list` in Python. Reference semantics are achieved by simply
retrieving the `IValue` contained in `ScriptList` in `toIValue` (invoked
when converting Python arguments to `IValues` before calling TorchScript
code).

**Test Plan**
This commit adds `TestScriptList` to `test_list_dict.py`, a set of tests
that check that all of the common list operations are supported
and that instances have reference semantics across the
Python/TorchScript boundary.

0dd90cceaf [package] track storages across lifetime of PackageExporter (#59735)
Summary:
Pull Request resolved: https://github.com/pytorch/pytorch/pull/59735

1. Fixes ABA storage identity problem during serialization for `torch.package` by keeping reference of serialized storages through lifetime of `PackageExporter` to prevent reuse of memory address. Achieved by extending logic used in solution to mobile's same issue.
2. Adds determinism to naming scheme of serialized storages in export code paths which utilize `tensor_cdata_naming_scheme`(introduced 2nd mapping in `StorageContext`, now maps `storage cdata ptr` -> `unique id`, `unique id` -> `c10::Storage`)
3. Additionally uses presence of a storage in the `StorageContext` instance as marker for if a storage has been serialized or not, removing the need to scan the `PythonStreamWriter` for presence of the storage's serialization file

b14c3205fd [JIT] Add torch._C.ScriptDict (#52659)
Summary:
Pull Request resolved: https://github.com/pytorch/pytorch/pull/52659

**Summary**
This commit adds `torch._C.ScriptDict`, a dictionary type that has reference
semantics across the Python/TorchScript boundary. That is, modifications
made to instances of `torch._C.ScriptDict` in TorchScript are visible in
Python even when it is not returned from the function. Instances can be
constructed by passing an instance of a Python dictionary to
`torch.jit.script`. In the case of an empty dictionary, its type is
assumed to be `Dict[str, Tensor]` to be consistent with the handling of
empty dictionaries in TorchScript source code.

`torch._C.ScriptDict` is implemented using a modified version of pybind's `stl_bind.h`-style bindings attached to `ScriptDict`, `ScriptDictIterator` and `ScriptDictKeyIterator`, wrapper classes around `c10::impl::GenericDict` and `c10::impl::GenericDict::iterator`. These bindings allow instances of `torch._C.ScriptDict` to be used as if it were a regular `dict` Python. Reference semantics are achieved by simply retrieving the `IValue` contained in `ScriptDict` in `toIValue` (invoked when converting Python arguments to `IValues` before calling TorchScript code).

**Test Plan**
This commit adds `TestScriptDict` to `test_list_dict.py`, a set of tests
that check that all of the common dictionary operations are supported
and that instances have reference semantics across the
Python/TorchScript boundary.

034a238bab [jit] Implement ScriptProfile to collect instruction profiles. (#57397)
Summary:
Pull Request resolved: https://github.com/pytorch/pytorch/pull/57397

Introduces two main classes in C++ runtime:

ScriptProfile is the implementation for enalbing and disabling interpreter
profiling in C++. This should be only used from Python, and we will add
corresponding Python API in the next diff.

InstructionSpan is a utility class to instrument execution of each single
instruction. A start timestamp is recorded in the consturctor, and an end
timestamp is recorded in the destructor. During destruction, this will send
runtime data to all enabled ScriptProfile instances.

Test Plan:
build/bin/test_jit --gtest_filter='ScriptProfileTest.Basic'
