  Explanation: Dynamo failed to run FX node with fake tensors: call_function <built-in method isclose of type object at 0x7f5f10575b20>(*(FakeTensor(..., size=(3,)), FakeTensor(..., size=(3,))), **{'rtol': 1.3e-06, 'atol': 1e-05, 'equal_nan': True}): got RuntimeError('tls_on_entry.has_value() INTERNAL ASSERT FAILED at "/__w/pytorch/pytorch/aten/src/ATen/core/PythonFallbackKernel.cpp":53, please report a bug to PyTorch. ')
  Hint: Your code may result in an error when running in eager. Please double check that your code doesn't contain a similar error when actually running eager/uncompiled. You can do this by removing the `torch.compile` call, or by using `torch.compiler.set_stance("force_eager")`.

PR fix notes

PR #180636: [dynamo] restore Python dispatch TLS across graph breaks

Description (problem / solution / changelog)

Stack from ghstack (oldest at bottom):

  • -> #180636

Fix a flaky functorch+dynamo failure where Python fallback can be entered without a valid TLS snapshot, or with Python dispatch TLS leaked past the compiled frame. Use MaybeSetTLSOnEntryGuard in Python fallback, and restore the saved dispatch TLS around the compiled call so later eager ops like assertEqual/isclose/module setup do not trip the same failure after a graph break.

Add a regression test covering the graph-break path that previously left Python=True and PythonTLSSnapshot=False in local dispatch TLS.

This appears related to the flaky test disables in #180299, #180300, #180320, #180321, #180322, #180336, #180337, and likely the same failure family as #180436, #180555, #180590, #180591, and #180592. Though I could not repro any of them locally.

torch._dynamo.exc.TorchRuntimeError: RuntimeError when making fake tensor call
  Explanation: Dynamo failed to run FX node with fake tensors: call_function <built-in method isclose of type object at 0x7f5f10575b20>(*(FakeTensor(..., size=(3,)), FakeTensor(..., size=(3,))), **{'rtol': 1.3e-06, 'atol': 1e-05, 'equal_nan': True}): got RuntimeError('tls_on_entry.has_value() INTERNAL ASSERT FAILED at "/__w/pytorch/pytorch/aten/src/ATen/core/PythonFallbackKernel.cpp":53, please report a bug to PyTorch. ')
  Hint: Your code may result in an error when running in eager. Please double check that your code doesn't contain a similar error when actually running eager/uncompiled. You can do this by removing the `torch.compile` call, or by using `torch.compiler.set_stance("force_eager")`.

To execute this test, run the following from the base repo dir:
    PYTORCH_TEST_WITH_DYNAMO=1 python test/functorch/test_eager_transforms.py TestComposabilityCPU.test_vmap_grad_cpu

This test was disabled because it is failing in CI. See recent examples and the most recent trunk workflow logs.

Over the past 6 hours, it has been determined flaky in 3 workflow(s) with 3 failures and 3 successes.

Debugging instructions (after clicking on the recent samples link): DO NOT ASSUME THINGS ARE OKAY IF THE CI IS GREEN. We now shield flaky tests from developers so CI will thus be green but it will be harder to parse the logs. To find relevant log snippets:

  1. Click on the workflow logs linked above
  2. Click on the Test step of the job so that it is expanded. Otherwise, the grepping will not work.
  3. Grep for test_vmap_grad_cpu
  4. There should be several instances run (as flaky tests are rerun in CI) from which you can study the logs.

torch._dynamo.exc.TorchRuntimeError: RuntimeError when making fake tensor call
  Explanation: Dynamo failed to run FX node with fake tensors: call_function <built-in method isclose of type object at 0x7f5f10575b20>(*(FakeTensor(..., size=(3,)), FakeTensor(..., size=(3,))), **{'rtol': 1.3e-06, 'atol': 1e-05, 'equal_nan': True}): got RuntimeError('tls_on_entry.has_value() INTERNAL ASSERT FAILED at "/__w/pytorch/pytorch/aten/src/ATen/core/PythonFallbackKernel.cpp":53, please report a bug to PyTorch. ')
  Hint: Your code may result in an error when running in eager. Please double check that your code doesn't contain a similar error when actually running eager/uncompiled. You can do this by removing the `torch.compile` call, or by using `torch.compiler.set_stance("force_eager")`.

extent analysis

TL;DR

The most likely fix for the failing test test_vmap_grad_cpu is to investigate and resolve the RuntimeError caused by the isclose function when running with fake tensors in Dynamo.

Guidance

  • Investigate the RuntimeError caused by the isclose function when running with fake tensors in Dynamo.
  • Check the code for any potential errors that may cause the isclose function to fail when running in eager mode.
  • Try removing the torch.compile call or using torch.compiler.set_stance("force_eager") to see if the error persists.
  • Set TORCHDYNAMO_VERBOSE=1 and TORCH_LOGS="+dynamo" to get more detailed internal stack traces and logs.

Example

No specific code example is provided as the issue is related to a complex error in the PyTorch library.

Notes

The error message suggests that the issue is related to the isclose function and fake tensors in Dynamo. The provided stack trace and error message are quite detailed, but the root cause of the issue is not immediately clear. Further investigation and debugging are required to resolve the issue.

Recommendation

Apply a workaround by setting PYTORCH_PRINT_REPRO_ON_FAILURE=0 to suppress the error message, and then investigate the issue further by checking the code and logs.
