Pytorch tensor apply
WebFrom the Python frontend, a nestedtensor can be created from a list of tensors. We denote nt [i] as the ith tensor component of a nestedtensor. nt = torch.nested.nested_tensor( [torch.arange(12).reshape( 2, 6), torch.arange(18).reshape(3, 6)], dtype=torch.float, device=device) print(f"{nt=}") Web1 day ago · I tried one solution using extremely large masked tensors, e.g. x_masked = masked_tensor (x [:, :, None, :].repeat ( (1, 1, M, 1)), masks [None, None, :, :].repeat ( (b, c, 1, 1))) out = torch.mean (x_masked, -1).get_data () and while this is lightning fast, it results in extremely large tensors and is unusable.
