What does this PR do?
keras2onnx has been dead for a while, with the development being made in tf2onnx. It is the successor, yet also retrocompatible.
In fact, our tests were failing right at the import level (i.e.
import keras2onnxfails with recentkerasversions). These changes fix the tests for TF+ONNX.Example of test command that gets fixed with this PR:
