"Protobuf parsing failed" when onnxruntime opens a quantized model
HelloI used optimum 1.18 to create a quantized onnx model:optimum-cli onnxruntime quantize --avx2 --onnx_model model.onnx --output quantized_model.onnxThen I tried to open quantized_model.onnx with C++ API onnxruntime-1.17.1 shared library but it was rejected due to “Protobuf parsing failed”.Notes. 1) the same onnxruntime binary is able to open and load non-quantized model.onnx. 2) the quantized model can be opened with Netron.Anyone has an idea what I am missing?Thank you
