WebIf you just want to reshape tensors, use torch.reshape. If you're also concerned about memory usage and want to ensure that the two tensors share the same data, use torch.view. Tensor.reshape() is more robust. It will work on any tensor, while Tensor.view() works only on tensor t where t.is_contiguous()==True. Webtorch.reshape (x, (*shape)) returns a tensor that will have the same data but will reshape the tensor to the required shape. However, the number of elements in the new tensor has to be the same as that of the original tensor. reshape () function will return a view of the original tensor whenever the array is contiguous (or has contiguous strides).
