Project requires an old version of Protobuf about tensorflow-onnx HOT 4 OPEN

Thank you for the fast response. Shouldn't tensorflow indicate the prereq version of protobuf that it requires. tf2onnx should not need to specify versions required by another project, right?

Apparently only tensorflow > 2.10 does that. That's probably why many tests fail with older tensorflow versions in #2327.

Thanks for your comments..

At this moment, tf2onnx is still designed to support older TensorFlow versions as many as possible and some of them could not work on a version above 3.20.x. In addition, couple of dependencies of tf2onnx also required the protobuf version ~= 3.20.0, so we can't upgrade its version in setup.py now.

Here is an idea: Python 3.11 is supported since tensorflow 2.12. I think it's safe to say on Python >= 3.11, tensorflow already properly specifies compatible protobuf versions. How about something like this?

install_requires=[
    # (other dependencies)
    'protobuf~=3.20; python_version < "3.11"',
    'protobuf; python_version >= "3.11"',
]

In addition, couple of dependencies of tf2onnx also required the protobuf version ~= 3.20.0

I didn't check other dependencies. Such a trick may apply as well.
