| .. note:: | |
| In some circumstances when using the CUDA backend with CuDNN, this operator | |
| may select a nondeterministic algorithm to increase performance. If this is | |
| undesirable, you can try to make the operation deterministic (potentially at | |
| a performance cost) by setting ``torch.backends.cudnn.deterministic = | |
| True``. | |
| Please see the notes on :doc:`/notes/randomness` for background. |
