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

Question

I encountered it while executing from object_detection.utils import label_map_util in jupyter notebook. It is actually the tensorflow object detection tutorial

For others looking into this more recently newer google libraries are using proto plus, a wrapper for python proto messages. Using this helper function worked for me (cred: tobked)

import json

import proto

def proto_message_to_dict(message: proto.Message) -> dict:
    """Helper method to parse protobuf message to dictionary."""
    return json.loads(message.__class__.to_json(message))
