Hi @Asadashino-o, could you please try to pip install coremltools in a clean environment?

Hi @Asadashino-o, could you please try to pip install coremltools in a clean environment?

Thanks for your suggestion! However I get knowledge from my classmates, it may cause some errors in Linux ? (He told me that he once encountered problems while using Coremltools7+on Linux and successfully ran it on MacOS) That’s why?

Also, does Coremltools7+no longer support converting ONNX to Coreml?

Yes that could be the case. The Core ML framework is part of MacOS, so any functionality depending on Core ML framework can only run on MacOS. AFAIK, on Linux we only guarantee conversion and serialization of models.

Also, does Coremltools7+no longer support converting ONNX to Coreml?

Let's continue our ONNX->CoreML discussion in #2225
