Onnx nchw to nhwc

WebRecall that the ONNX format uses the NCHW format while TF-Lite uses the NHWC format to store the model tensors. While doable, converting from one format to the other is non-trivial. As such, additional steps are required to do the conversion. The first step is converting the .onnx model to the OpenVino intermediate format. Web1 de jun. de 2024 · I think it was the default format in LuaTorch and I don’t know, why this format was preferred over NHWC. However, note that PyTorch has now experimental channels-last support. By using this, you would still create and index the tensors as NCHW to guarantee backwards compatibility. About the ordering, I think NCHW is much more …
