inference_classifier.py WARNING

[jazjamau]

Hi,
Thank you for your amazing video on YouTube, and for sharing the code here. I got an error (warning) on inference_classifier.py

\sign-language-detector-python\Lib\site-packages\google\protobuf\symbol_database.py:55: UserWarning: SymbolDatabase.GetPrototype() is deprecated. Please use message_factory.GetMessageClass() instead. SymbolDatabase.GetPrototype() will be removed soon.

Please let me know what you suggest to avoid the warning.
Thanks heaps,
Jaz
