Type Error on import of Tensorflow Code Block 3.7 Chapter 03

Chapter 03 Notebook Code 3.7 first cell cause type error on import of Tensorflow as tf

TypeError: Descriptors cannot not be created directly. If this call came from a _pb2.py file, your generated code is out of date and must be regenerated with protoc >= 3.19.0. If you cannot immediately regenerate your protos, some other possible workarounds are:

1. Downgrade the protobuf package to 3.20.x or lower.
2. Set PROTOCOL_BUFFERS_PYTHON_IMPLEMENTATION=python (but this will use pure-Python parsing and will be much slower).

Thanks for reading the book. Are you using the library versions from the environment.yml file?
