WebJan 10, 2024 · Why is Pytorch float32 matmul executed differently on gpu and cpu? An even more confusing experiment involves float16, as follows: a = torch.rand (3, 4, dtype=torch.float16) b = torch.rand (4, 5, dtype=torch.float16) print (a.numpy ()@b.numpy () - a@b) print ( (a.cuda ()@b.cuda ()).cpu () - a@b) these two results are all non-zero.

Webtorch.cuda.amp provides convenience methods for mixed precision, where some operations use the torch.float32 ( float) datatype and other operations use torch.float16 ( half ). Some ops, like linear layers and convolutions, are much faster in float16 or bfloat16. Other ops, like reductions, often require the dynamic range of float32. Webtorch.float16 quantization parameters (varies based on QScheme): parameters for the chosen way of quantization torch.per_tensor_affine would have quantization parameters …

If your code doesn't create nan/inf numbers or turn a non- 0 into a 0 with float32, then it shouldn't do it with bfloat16 either, roughly speaking. So, if your hardware supports it, I'd pick that. Check out AMP if you choose float16. Share Follow
WebJul 30, 2024 · I have a huge tensor (Gb level) on GPU and I want to convert it to float16 to save some GPU memory. How could I achieve this?

I've checked the ONNX graphs and the …
WebMay 31, 2024 · Sorted by: 1 As I know, a lot of CPU-based operations in Pytorch are not implemented to support FP16; instead, it's NVIDIA GPUs that have hardware support for FP16 (e.g. tensor cores in Turing arch GPU) and PyTorch followed up since CUDA 7.0 (ish).
