Weberror: failed to poll model repository: INVALID_ARG — model input NHWC/NCHW require 3 dims for onnx_model. output: similar to input primarily to indicate the output node exposed to trt server. WebBuild up the NCHW inference architecture: If the model is trained in NHWC, we should make sure NCHW architecture can consume the pretrained weights. Generally, most layers could work well directly in NHWC -> NCHW conversion except Reshape, Flatten, Dense and Softmax applied to feature map; Input shape of model should be set. tsamrtsafe.comWebHowever, 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.

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.
