unsupported ops

It is necessary to keep the subgraph without output, such as the subgraph where LookupTableImportV2 is located in StaticHashTable. Because tf2onnx does not fully support StaticHashTable, may need a custom...

Since tf 2.17 version, keras._tf_keras.keras.backend.reset_uids does not exist anymore which breaks CI.
