So… I don’t know how to reshape tensors exactly. For example, I have a [2, 512, 10, 10] <-- (batch_num, C, H ,W) tensor. Let’s assume that I apply some channel-wise operations to each cells of the tensor. In this case, the operations applied 200 times (2 * 10 * 10, batch_num * H * W) to the tensor.
