Hi @AK391, Thank you for catching it. I guess for the original version of the model, mobilenetv2-7.onnx might work. Could you please try this old model instead? There were several updates for mobilenetv2-7.onnx (for instance, https://github.com/onnx/models/pull/410) and something might not be supported by the mxnet-onnx yet. As you can see from here, mxnet-onnx does not support it even for now. The notebook in onnx/models needs to be updated as well to prevent future confusion.

Thank you, @jcwchen . I encountered the same issue. The old model you specified worked!
