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:

Protocol buffers (Protobuf) are a language-agnostic data serialization format developed by Google. Protobuf is great for the following reasons: Low data volume: Protobuf makes use of a binary format, which is more compact than other formats such as JSON. Persistence: Protobuf serialization is backward-compatible.
The protoc version 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 The version in pip was a bit outdated.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 with
pip install --upgrade protobuf the problem was solved.

These three commands solved it for me:
pip uninstall protobuf python3-protobuf pip install --upgrade pip pip install --upgrade protobuf If you love us? You can donate to us via Paypal or buy me a coffee so we can maintain and grow! Thank you!
