Summary: Context: https://github.com/pytorch/pytorch/pull/53299#discussion_r587882857 These are the only hand-written parts of this diff: - the addition to `.github/workflows/lint.yml` - the file endings changed in these four files (to appease FB-internal land-blocking lints): - `GLOSSARY.md` - `aten/src/ATen/core/op_registration/README.md` - `scripts/README.md` - `torch/csrc/jit/codegen/fuser/README.md` The rest was generated by running this command (on macOS): ``` git grep -I -l ' $' -- . ':(exclude)**/contrib/**' ':(exclude)third_party' | xargs gsed -i 's/ *$//' ``` I looked over the auto-generated changes and didn't see anything that looked problematic. Pull Request resolved: https://github.com/pytorch/pytorch/pull/53406 Test Plan: This run (after adding the lint but before removing existing trailing spaces) failed: - https://github.com/pytorch/pytorch/runs/2043032377 This run (on the tip of this PR) succeeded: - https://github.com/pytorch/pytorch/runs/2043296348 Reviewed By: walterddr, seemethere Differential Revision: D26856620 Pulled By: samestep fbshipit-source-id: 3f0de7f7c2e4b0f1c089eac9b5085a58dd7e0d97

torch.backends
|
|
==============
|
|
|
|
`torch.backends` controls the behavior of various backends that PyTorch supports.
|
|
|
|
These backends include:
|
|
|
|
- ``torch.backends.cuda``
|
|
- ``torch.backends.cudnn``
|
|
- ``torch.backends.mkl``
|
|
- ``torch.backends.mkldnn``
|
|
- ``torch.backends.openmp``
|
|
|
|
|
|
torch.backends.cuda
|
|
^^^^^^^^^^^^^^^^^^^
|
|
|
|
.. autofunction:: torch.backends.cuda.is_built
|
|
|
|
.. attribute:: torch.backends.cuda.matmul.allow_tf32
|
|
|
|
A :class:`bool` that controls whether TensorFloat-32 tensor cores may be used in matrix
|
|
multiplications on Ampere or newer GPUs. See :ref:`tf32_on_ampere`.
|
|
|
|
.. attribute:: torch.backends.cuda.cufft_plan_cache
|
|
|
|
``cufft_plan_cache`` caches the cuFFT plans
|
|
|
|
.. attribute:: size
|
|
|
|
A readonly :class:`int` that shows the number of plans currently in the cuFFT plan cache.
|
|
|
|
.. attribute:: max_size
|
|
|
|
A :class:`int` that controls cache capacity of cuFFT plan.
|
|
|
|
.. method:: clear()
|
|
|
|
Clears the cuFFT plan cache.
|
|
|
|
|
|
torch.backends.cudnn
|
|
^^^^^^^^^^^^^^^^^^^^
|
|
|
|
.. autofunction:: torch.backends.cudnn.version
|
|
|
|
.. autofunction:: torch.backends.cudnn.is_available
|
|
|
|
.. attribute:: torch.backends.cudnn.enabled
|
|
|
|
A :class:`bool` that controls whether cuDNN is enabled.
|
|
|
|
.. attribute:: torch.backends.cudnn.allow_tf32
|
|
|
|
A :class:`bool` that controls where TensorFloat-32 tensor cores may be used in cuDNN
|
|
convolutions on Ampere or newer GPUs. See :ref:`tf32_on_ampere`.
|
|
|
|
.. attribute:: torch.backends.cudnn.deterministic
|
|
|
|
A :class:`bool` that, if True, causes cuDNN to only use deterministic convolution algorithms.
|
|
See also :func:`torch.are_deterministic_algorithms_enabled` and
|
|
:func:`torch.use_deterministic_algorithms`.
|
|
|
|
.. attribute:: torch.backends.cudnn.benchmark
|
|
|
|
A :class:`bool` that, if True, causes cuDNN to benchmark multiple convolution algorithms
|
|
and select the fastest.
|
|
|
|
|
|
torch.backends.mkl
|
|
^^^^^^^^^^^^^^^^^^
|
|
|
|
.. autofunction:: torch.backends.mkl.is_available
|
|
|
|
|
|
torch.backends.mkldnn
|
|
^^^^^^^^^^^^^^^^^^^^^
|
|
|
|
