3cda34ebde [2/N] Apply ruff UP035 check in torch files (#164054)
This is the result of applying the ruff `UP035` check.
`Callable` is imported from `collections.abc` instead of `typing`.
`TypeAlias` is also imported from `typing`.
This PR is the follow-up of #163947.

189a054cfb Remove guard_size_oblivious from default contiguity python check, and add aten.sym_is_contiguous. [attempt2] (#160869)
[relanding again after fixing internal build]
Summary:
This might cause some new DDEs on call sites that do not use is_contiguous_or_false() or sym_is_contiguous()
but want to find those call sites to handle this properly by calling  is_contiguous_or_false() and not is_contiguous() explitly when appropriate.
I had to fix one issue after removing the implicit size oblivious reasoning. here is context

we defined in this https://github.com/pytorch/pytorch/pull/157472 sym_is_contiguous to be the function computing contiguity for dynamic shapes in c++. It returns a symbolic expression that represents contiguity and guaranteed not to throw a DDE.

when people call is_contiguous we do sym_is_contiguous().guard_bool()
when people call is_contiguous_or_false we do sym_is_contiguous().guard_or_false()

one issue not handled well was this path
```
c10::SymBool TensorImpl::sym_is_contiguous_custom(
    at::MemoryFormat memory_format) const {
  if (C10_UNLIKELY(matches_python_custom(SizesStridesPolicy::CustomStrides))) {
    return pyobj_slot_.load_pyobj_interpreter()->is_contiguous(
        this, memory_format);
  }

  return sym_is_contiguous_default(memory_format);
}
```
namely if we call sym_is_contiguous_custom but we have matches_python_custom(SizesStridesPolicy::CustomStrides) return true , then we used to call is_contiguous(this, memory_format);

This used to go through the load_pyobj_interpreter and end up calling the python is_contiguous call which used implicit size oblivious reasoning.
once we removed that implicit size oblivious reasoning, the right thing we want is to call
return pyobj_slot_.load_pyobj_interpreter()->sym_is_contiguous(this, memory_format);
otherwise we would get DDE even if the caller is doing sym_is_contiguous.

so I had to define it for pyinterpreter, and then I had to override it for nested tensors.

7e83d50845 Inductor logging + analysis of torch.profile (#149697)
Prereqs:
 - https://github.com/pytorch/pytorch/pull/152708

Features:
1. Adds inductor's estimate of flops and bandwidth to the json trace events that perfetto uses.
1. Only use the tflops estimation from triton if we don't have the info from the datasheet because Triton's estimates are inaccurate. I have a backlog item to fix triton flops estimation upstream. New `DeviceInfo` class, and new function `get_device_tflops`.
1. New helpers `countable_fx` and `count_flops_fx` helps get the flops of an `fx.Node`.
1. Extends Triton `torch.profiler` logging to `DebugAutotuner`.
1. New script `profile_analysis.py`: `--augment_trace` adds perf estimates to any perfetto json trace, `--analyze` creates a summary table of these perf estimates, and `--diff` will compare two traces side by side:

47f10d0ad0 Inductor logging + analysis of torch.profile (#149697)
Prereqs:
 - https://github.com/pytorch/pytorch/pull/152708

Features:
1. Adds inductor's estimate of flops and bandwidth to the json trace events that perfetto uses.
1. Only use the tflops estimation from triton if we don't have the info from the datasheet because Triton's estimates are inaccurate. I have a backlog item to fix triton flops estimation upstream. New `DeviceInfo` class, and new function `get_device_tflops`.
1. New helpers `countable_fx` and `count_flops_fx` helps get the flops of an `fx.Node`.
1. Extends Triton `torch.profiler` logging to `DebugAutotuner`.
1. New script `profile_analysis.py`: `--augment_trace` adds perf estimates to any perfetto json trace, `--analyze` creates a summary table of these perf estimates, and `--diff` will compare two traces side by side:

347ace4c7a Inductor logging + analysis of torch.profile (#149697)
Prereqs:
 - https://github.com/pytorch/pytorch/pull/152708

Features:
1. Adds inductor's estimate of flops and bandwidth to the json trace events that perfetto uses.
1. Only use the tflops estimation from triton if we don't have the info from the datasheet because Triton's estimates are inaccurate. I have a backlog item to fix triton flops estimation upstream. New `DeviceInfo` class, and new function `get_device_tflops`.
1. New helpers `countable_fx` and `count_flops_fx` helps get the flops of an `fx.Node`.
1. Extends Triton `torch.profiler` logging to `DebugAutotuner`.
1. New script `profile_analysis.py`: `--augment_trace` adds perf estimates to any perfetto json trace, `--analyze` creates a summary table of these perf estimates, and `--diff` will compare two traces side by side:

This reverts commit 060838c2312ad207c7afe2c86f8a484afea5f328.

Reverted https://github.com/pytorch/pytorch/pull/149697 on behalf of https://github.com/clee2000 due to broke a bunch of tests internally D76299454, probably also broke rocm inductor/test_analysis.py::TestAnalysisCUDA::test_augment_trace_against_flop_counter_maxat0_cuda_float16 [GH job link](https://github.com/pytorch/pytorch/actions/runs/15545277599/job/43766911025) [HUD commit link](060838c231) ([comment](https://github.com/pytorch/pytorch/pull/149697#issuecomment-2959747153))

060838c231 Inductor logging + analysis of torch.profile (#149697)
Prereqs:
 - https://github.com/pytorch/pytorch/pull/152708

Features:
1. Adds inductor's estimate of flops and bandwidth to the json trace events that perfetto uses.
1. Only use the tflops estimation from triton if we don't have the info from the datasheet because Triton's estimates are inaccurate. I have a backlog item to fix triton flops estimation upstream. New `DeviceInfo` class, and new function `get_device_tflops`.
1. New helpers `countable_fx` and `count_flops_fx` helps get the flops of an `fx.Node`.
1. Extends Triton `torch.profiler` logging to `DebugAutotuner`.
1. New script `profile_analysis.py`: `--augment_trace` adds perf estimates to any perfetto json trace, `--analyze` creates a summary table of these perf estimates, and `--diff` will compare two traces side by side:

e5afbe3124 Inductor logging + analysis of torch.profile (#149697)
Prereqs:
 - https://github.com/pytorch/pytorch/pull/152708

Features:
1. Adds inductor's estimate of flops and bandwidth to the json trace events that perfetto uses.
1. Only use the tflops estimation from triton if we don't have the info from the datasheet because Triton's estimates are inaccurate. I have a backlog item to fix triton flops estimation upstream. New `DeviceInfo` class, and new function `get_device_tflops`.
1. New helpers `countable_fx` and `count_flops_fx` helps get the flops of an `fx.Node`.
1. Extends Triton `torch.profiler` logging to `DebugAutotuner`.
1. New script `profile_analysis.py`: `--augment_trace` adds perf estimates to any perfetto json trace, `--analyze` creates a summary table of these perf estimates, and `--diff` will compare two traces side by side:

43496e9b90 [NJT] fix flop counter for SDPA & test (#147032)
Fixes 3 issues:
1. The test wasn't actually testing SDPA: both were checking cuda, and the inputs to SDPA were not transposed.
2. FlopCounterMode has been renamed _FlopCounterMode (and a wrapper named FlopCounterMode has been added)
3. offsets_to_list also needs to ignore the actual offset values if offsets is a meta tensor.

4fa72168ea FlopCounterMode: Decompose ops for inference mode (#138508)
Fixes #126268

I've basically followed @ezyang suggestion (I think) to use `func.decompose(...)`. Since `__torch_dispatch__` won't be called a second time for the same op, I've added a second `TorchDispatchMode` (`_DecomposedCounterMode`) that simpy dispatches to the parent flop counter. Using `self` as the inner context manager is not possible, since the second call to `__enter__` would re-initialize the counter's tracking state.

Let me know if there's something wrong with this implementation, since I'm quite unsure how the decomposition thing actually works :D

1962f9475f [NJT][flop counter] attention: if offsets are fake, use max seqlen (#132356)
The flop counter is used by the partitioner, in which case the tensors passed in can be fake.

The flop computations for nested attention use the offsets to determine the actual amount of compute that will be done. But when the offsets are fake, we end up with unbacked symints (from `(offsets[1:] - offsets[:-1]).to_list()`). If we find that the offsets are fake or functional tensors, then use the max sequence length instead.

a3cdbd8189 [FlopCounterMode] Fix register_flop_formula (#131777)
Previously, FlopCounterMode would ignore any custom ops registered
through `register_flop_formula`. The problem was:
- register_flop_formula(target) requires target to be an OpOverloadPacket.
- register_flop_formula used register_decomposition to populate its registry
- register_decomposition decomposes the OpOverloadPacket into OpOverload before
  putting it into the registry
- FlopCounterMode ignores OpOverloads in its registry (it assumes the
  registry is a dictionary mapping OpOverloadPacket to flop formula).

register_decomposition is too heavy of a hammer, plus this isn't a
decomposition, so I changed the registration mechanism.

Test Plan:
- new tests

f845a7a91a [cuDNN][SDPA] Remove TORCH_CUDNN_SDPA_ENABLED=1, enable cuDNN SDPA by default on H100 and 2nd on other archs >= sm80 (#125343)
Looks like one of the first failures seen is `test_causal_variants_compile_causal_variant_CausalVariant_LOWER_RIGHT_shape0_cuda` when `test_causal_variants_causal_variant_CausalVariant_LOWER_RIGHT_shape0_cuda` passes.

What seems interesting here is that the `torch.compile` version fails while the eager version passes. Not sure what the difference would be here...

Nevertheless, is there a recommended mechanism to skip cuDNN SDPA as a backend for this test? CC @drisspg

9e85d3d830 Add "accurate" FlopCounter implementations for NestedTensor SDPA kernels (#125776)
This adds implementations for:
* _flash_attention_forward
* _efficient_attention_forward
* _flash_attention_backward
* _efficient_attention_backward

These flop counts are implemented as follows:
* Unbind the batch elements
* Calculate flops individually for each element in the batch
* Sum the final result

This means that we are accessing the concrete sequence lengths (which could be slow, and may trigger a GPU/CPU sync); but, the FLOP numbers will vary with the sparsity of the NestedTensor - more accurate than if we just assumed we padded everything.

76a26a885d Add module tracker (#125352)
This does a few things that were originally a few PRs but I am on a new machine and don't have ghstack.
If it is too problematic to review, I can re-split, just let me know.
This does:
- Cleanup context manager use in test_flop_counter
- Remove need for mod argument in FlopCounterMode, warning about it
- Re-implement a Module tracker from scratch using global forward Module use and multi_grad_hook (we cannot use global backward Module hook because they don't look for nested Tensor and they're custom Function based instead of multi_grad_hook).
- Update FlopCouterMode to use the new ModuleTracker. All the existing test suite passes as-is (only changes there are new tests and refactoring mentioned above)

2bbfb70831 ignore unsupported module from flop counter (#125346)
Summary:
Torchscript modules do not support forward hooks and thus can't work with flop_counter context manager for hierarchical output by passing a module to FlopCounterMode on construction.

Currently any module that includes a script module causes an exception to be thrown so adding a try/catch to ignore any script modules for forward hooks.

3fe437b24b [BE]: Update flake8 to v6.1.0 and fix lints (#116591)
Updates flake8 to v6.1.0 and fixes a few lints using sed and some ruff tooling.
- Replace `assert(0)` with `raise AssertionError()`
- Remove extraneous parenthesis i.e.
  - `assert(a == b)` -> `assert a == b`
  - `if(x > y or y < z):`->`if x > y or y < z:`
  - And `return('...')` -> `return '...'`

* Enable PERF402. Makes code more efficient and succinct by removing useless list copies that could be accomplished either via a list constructor or extend call. All test cases have noqa added since performance is not as sensitive in that folder.
