title: How to solve “AttributeError: module 'google.protobuf.descriptor' has no attribute '_internal_create_key”?
body: <p>I am experinecing this issue while running from object_detection.utils import label_map_util in jupyter notebook. It is actually the tensorflow object detection tutorial notebook. I have checked the similar question <a href="https://stackoverflow.com/q/61922334/11758585">How to solve &quot;AttributeError: module &#39;google.protobuf.descriptor&#39; has no attribute &#39;_internal_create_key&quot;?</a> but the answers didn't help me. I couldn't find what I should do.</p>
