This worked for me:

pip3 install --no-binary :all: gopro2gpx

Otherwise, downloading the repository and installing via setup.py

I have seen this issue before, I just submitted an PR (#15) to hopefully fix it. Until this is merged you can install directly from the PR with
pip install git+https://github.com/simske/gopro2gpx@fix_entrypoint
