WebHowever, ONNX only supports NCHW. As a result, if the original model is in NHWC format, when the model is converted extra transposes may be added. The tensorflow-onnx converter does remove many of these transposes, but if this doesn’t help sufficiently, consider retraining the model using NCHW. Mitigate high latency variance 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.

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.
