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If this call came from a _pb2.py file, your generated code is out of date and must be regenerated with protoc 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).

What version of tensorboard are you currently running? We've been redirecting the what-if tool to the learning interpretability tool since version 2.12.3 since the what if tool was no longer maintained.

Closing since the referenced plugin is no longer included as part of newer releases, feel free to reopen if you have other comments.
