WebNov 4, 2024 · Hi, I think torch.tensor — PyTorch 1.7.0 documentation and torch.as_tensor — PyTorch 1.7.0 documentation have explained the difference clearly but in summary, torch.tensor always copies the data but torch.as_tensor tries to avoid that! In both cases, they don’t accept sequence of tensors. The more intuitive way is stacking in a given … Web13 hours ago · This loop is extremely slow however. Is there any way to do it all at once in pytorch? It seems that x[:, :, masks] doesn't work since masks is a list of masks. Note, each mask has a different number of True entries, so simply slicing out the relevant elements from x and averaging is difficult since it results in a nested/ragged tensor.
