How I make a PyTorch model bit-identical outputs across different GPUs, cuDNN versions, and CPU fallback, with no source of nondeterminism anywhere?...at step 0 - identical.. . Compared after step 1 - already differs.. . My question: How do I guarantee bit-identical training across these hardware and library configurations?.Stack Overflow [pytorch]Zi Ba	Stack Overflow [pytorch]Zi Ba1 votes, 1 replies	Oct 2yesterday
[aot_autograd] wrong gradients for `torch.linalg.pinv` and `torch.linalg.matrix_sqrth` with complex input under torch.compile (aot_eager and inductor); eager, functorch and Dynamo-only are correct### 🐛 Describe the bug Summary. Eager and torch.compile do not produce the same gradient for `torch.linalg.pinv` and `torch.linalg.matrix_sqrth` on complex input: eager, `torch.func.grad` and `torch.compile(backend="eager")` agree with a complex128 reference to 1e-5, while...pytorch/pytorchcuiliaomei-beep	pytorch/pytorchcuiliaomei-beep1 reactions, 1 replies	Sep 152 weeks ago
