Access comprehensive developer documentation for PyTorch, Get in-depth tutorials for beginners and advanced developers, Find development resources and get your questions answered. Data is stupidly large, so you can't expect me to join this competition. If your dataset does not contain the background class, you should not have 0 in your labels.For example, assuming you have just two classes, cat and dog, you can define 1 (not 0) to represent cats and 2 to represent dogs.So, for instance, if one of the images has both classes, your labels tensor should look like [1,2]. torchvision.get_image_backend [source] ¶ Gets the name of the package used to load images. For modern deep neural networks, GPUs often provide speedups of 50x or greater, so unfortunately numpy won’t be enough for modern deep learning..
