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 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.
