How to solve “AttributeError: module 'google.protobuf.descriptor' has no attribute '_internal_create_key”?

问题

I encountered it while executing from object_detection.utils import label_map_util in jupyter notebook. It is actually the tensorflow object detection tutorial notebook(it comes with the tensorflow object detection api) The complete error log:

The below three commands solved it for me:
pip uninstall protobuf python3-protobuf
pip install --upgrade pip
pip install --upgrade protobuf
Hope this helps.

回答2:

This is a solution which worked for me I'm not sure if it'll work for others.

The protoc verion I got through pip show protobuf and protoc --version were different. The version in pip was a bit outdated after I upgraded the pip version the problem was solved.

In order to upgrade it use pip install --upgrade protobuf

After trying many different solutions (i'm working on a Mac) the one that worked for me is to reinstall protobuf using:

PROTOC_ZIP=protoc-3.7.1-osx-x86_64.zip
curl -OL https://github.com/protocolbuffers/protobuf/releases/download/v3.7.1/$PROTOC_ZIP
sudo unzip -o $PROTOC_ZIP -d /usr/local bin/protoc
sudo unzip -o $PROTOC_ZIP -d /usr/local 'include/*'
rm -f $PROTOC_ZIP

As is highlighted in this article
