This warning is a known issue that I raised a while ago in ONNX Runtime repo.

Note that this is a warning, so the inference itself should work fine and produce correct results. However, due to the missing shape information, it might be possible that the inferred shape would be incorrect so checking the output shape against the expected one would be a good idea.
