AttributeError: module 'google.protobuf.descriptor' has no attribute '_internal_create_key

We upgrade to the latest version 0.8.1, which seems to bring an error.

AttributeError: module 'google.protobuf.descriptor' has no attribute '_internal_create_key'

Can you elaborate on how this error came up ? Or better yet, build a minimal reproducer ?

A quick search shows this is likely due to an older version of protobuf in your environment. Can to you try upgrading protobuf and see if that fixes things?

pip install -U protobuf

It works. Thanks. Should the requirements be updated either? Maybe a higher version of pb.

install_requires = ['grpcio>=1.11.0',
                    'protobuf>=3.5.0',
                    'pyyaml',
                    'cryptography']

I've also run into this issue. protobuf==3.12.2 is the minimum version that does not raise this error.

A MWE follows:

# python 3.7 - 3.9 raise this error
$ python -m venv .venv
$ source .venv/bin/activate
$ python -m pip install skein==0.8.1 protobuf==3.11.2
...
$ python
...
>>> import skein
Traceback (most recent call last):
