"WebJan 28, 2024 · The recommended way to build tensors in Pytorch is to use the following two factory functions: torch.tensor and torch.as_tensor. torch.tensor always copies the data. For example, torch.tensor(x) is equivalent to x.clone().detach(). torch.as_tensor always tries to avoid copies of the data. One of the cases where as_tensor avoids copying the … " - Cannot interpret torch.uint8 as a data type
