Whereas PyTorch on the other hand, thinks you want it to be looking at your 28 batches of 28 feature vectors. physio unterföhring

Elegant way to get subtensor by indices in pytorch?

WebConvolutions typically operate on four-dimensional tensors: a batch composed of N "images" of C channels of H x W feature maps. Deep learning frameworks commonly use NCHW and NHWC layouts in memory (the acronym lists the dimensions from the slowest to the fastest varying in memory).
