Databricks - python error when importing wheel distribution package

[Mohit_m]

In previous days all notebooks containing : 'import anomalydetection' worked just fine. There was no change in any configuration of the cluster, notebook or our imported library.

However recently notebooks just crashed with below error

Same happen also in the other clusters containing this library. 

Error:

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 If this call came from a _pb2.py file, your generated code is out of date and must be regenerated with protoc bigger= 3.19.0.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).

As workaround i've set env variable PROTOCOL_BUFFERS_PYTHON_IMPLEMENTATION=python and started to work. As per recommendation this may slow down operations, what could the other solution?

Solution: This is due to the latest version of protobuf library, please try to downgrade the library which should solve the issue

pip install protobuf==3.20.*

protobuf library versions which works: 3.20.1 if it does not work then try 3.18.1
