To Reproduce

cd coordinator
python3 setup.py bdist_wheel
python3 install dist/*.wheel

import graphscope
graphscope.set_option(show_log=True)
s = graphscope.session(cluster_type="hosts")

The packaging package to be installed by default in our environments; I think you can try to fix it by installing the packaging module manually--either using pip install packaging or conda install packaging.

pip3 install packaging work, and I think we should put packaging to requirements.txt of gscoordinator.

Thanks for bringing this up! The issue arises from not having the packaging module installed, and as you found, installing packaging manually fixes it.

We didn't have the module required in GraphScopedetails because it happened to be installed by default in our environments; we didn't realize that not everyone would have it by default. We are going to added it to the pip install requirements, so in all future versions it will be installed automatically if someone doesn't already have it.

So for now, if anyone else has this issue, they can fix it by installing the packaging module manually--either using pip install packaging or conda install packaging.

@lidongze0629 can this issue be fixed in release v0.6?

Fixes in Release v0.6.0
