08.05.2021 · Binary cross-entropy, as the name suggests is a loss function you use when you have a binary segmentation map. The CrossEntropy function, in PyTorch, expects the output from your model to be of the shape - [batch, num_classes, H, W] (pass this directly to your loss function) and the ground truth to be of shape [batch, H, W] where H, W in your case is 256, 256.

Constants¶ segmentation_models_pytorch.losses.constants. BINARY_MODE: str = 'binary' ¶. Loss binary mode suppose you are solving binary segmentation task. That mean yor have only one class which pixels are labled as 1, the rest pixels are background and labeled as 0.Target mask shape - (N, H, W), model output mask shape (N, 1, H, W).
