WebMar 24, 2024 · Your suggestion is better than what I did later, which is use cond = cond.type (dtype_float) where I switch off dtype_float = torch.cuda.FloatTensor or torch.FloatTensor. .float () will happily keep it on whichever device (CPU/GPU). I’ll edit that code snippet so if anybody copy/pastes, that’s already handled. WebJan 26, 2024 · A tensor in PyTorch is like a NumPy array containing elements of the same dtypes. A tensor may be of scalar type, one-dimensional or multi-dimensional. To convert an image to a tensor in PyTorch we use PILToTensor () and ToTensor () transforms. These transforms are provided in the torchvision.transforms package.
