WebFeb 24, 2024 · On PyTorch, the default memory format is channels first (NCHW). In case a particular operator doesn't have explicit support on channels last (NHWC), the channels last input would be treated as a non-contiguous NCHW tensor and thus generating a NCHW output, therefore the memory format propagation chain will be broken.
