Yeah, some op is unsupported – what options were you using for the image-classifier? Was this when trying to get the profile (-dump-profile), or load the profile for quantization (-load-profile)? Have you tried just running it in fp32 (i.e. without the mentioned options)?
For MODEL_LOADER_UNSUPPORTED_OPERATOR, the operator is unsupported in fp32 too, and we’d need to add support to the importer for it. We need to improve our error messages here – in the meantime could you just add a simple print statement just before the RETURN_ERR() in ONNXModelLoader::LoadOperator() to print the typeName to see what it is reporting as unsupported.
Also, feel free to open an issue for supporting whatever op it is on Github!
