How should I prepare my data for 'valid' convolutions? If you are using a multi-class segmentation use case and therefore nn.CrossEntropyLoss or nn.NLLLoss, your mask should not contain a channel dimension, but instead contain the class indices in the shape [batch_size, height, width].. PIL.NEAREST is a valid option, as it won’t distort your color codes or class indices. Developer Resources.
