torch.set_deterministic¶

torch.
set_deterministic
(d)[source]¶ Sets whether PyTorch operations must use “deterministic” algorithms. That is, algorithms which, given the same input, and when run on the same software and hardware, always produce the same output. When True, operations will use deterministic algorithms when available, and if only nondeterministic algorithms are available they will throw a :class:RuntimeError when called.
Warning
This feature is in beta, and its design and implementation may change in the future.
The following normallynondeterministic operations will act deterministically when d=True:
torch.nn.Conv1d
when called on CUDA tensortorch.nn.Conv2d
when called on CUDA tensortorch.nn.Conv3d
when called on CUDA tensortorch.nn.ConvTranspose1d
when called on CUDA tensortorch.nn.ConvTranspose2d
when called on CUDA tensortorch.nn.ConvTranspose3d
when called on CUDA tensortorch.bmm()
when called on sparsedense CUDA tensors
The following normallynondeterministic operations will throw a

A handful of CUDA operations are nondeterministic if the CUDA version is 10.2 or greater, unless the environment variable CUBLAS_WORKSPACE_CONFIG=:4096:8 or CUBLAS_WORKSPACE_CONFIG=:16:8 is set. See the CUDA documentation for more details: https://docs.nvidia.com/cuda/cublas/index.html#cublasApi_reproducibility If one of these environment variable configurations is not set, a
RuntimeError
will be raised from these operations when called with CUDA tensors:Note that deterministic operations tend to have worse performance than nondeterministic operations.
 Parameters
d (
bool
) – If True, force operations to be deterministic. If False, allow nondeterministic operations.
