It looks like your Conv data input is of shape (-1,3), which is incorrect. Are you able to share your ONNX model?

Thanks for reply. The ONNX model is uploaded to Google Drive. https://drive.google.com/file/d/1YLdNxVAfTLEi7g61pL2b2HJQPmR0Q1i4/view?usp=sharing

If the original ONNX model can run normally in OnnxRuntime, then it can be the result of a failed shape inference. You can check the Reshape Op in your ONNX graph. If the second argument of a Reshape Op is not from a single constant value tensor, but from other Op (like Concat), the inferred shape of the output of the Reshape Op can be all -1.
