Cannot import name 'anchor_generator_pb2' from 'object_detection.protos'

When running a verification script, this error outputs: cannot import name 'anchor_generator_pb2' from 'object_detection.protos'.
I have been stuck at this error for a long time, but I haven’t been able to solve it.
Any help is greatly appreciated!
Thank you

Have you checked?

Yes, that didn’t work.

Have you also looked at the mentioned fullthread?

Yup, that didn’t resolve it either.

As you have already a ticket I suppose you could track your issue there:
