Describe the bug

Getting None value not supported while converting a model using onnx-tf

ONNX model file

Cannot share the model ATM

Python, ONNX, ONNX-TF, Tensorflow version

This section can be obtained by running get_version.py from util folder.

While converting a speech model, I get following error:

    ValueError: None values not supported.

While searching for similar issues raised here, looks like some other OPs are supported already with dynamic size but not this one.

I also encountered the same problem. I found that this happens under Apple Mac m1-m2. It will be normal under windows. There is indeed a problem with the version of the library. It seems to be incompatible with Tensorflow version 2.14 and onnx. I hope onnx can solve it. This problem is that it cannot be converted on Apple, but it can be converted on Windows. It is a very strange thing.
