Error occur at kapture_localization/utils/symlink.py

When I follow the tutorial and do mapping, an error occurs with symlimk.py

$ kapture_pipeline_mapping.py -v info \

It seems there is no function name with 'guess_feature_name_from_path' in features.py. Problem was 'guess_feature_name_from_path', and I found related commit e54bad2.

I changed symlink.py to the old version(before e54bad2) and reinstall, and it works well. I didn't fully understand these codes, but I think it can be a temporary solution for this problem.

Hi, You must have mismatched versions of kapture / kapture-localization (for example kapture-localization from code and kapture from pip). the commit you reference have a twin in kapture where the guess_feature_name_from_path was added: 84944a6

Hi, My kapture, kapture-localization version is kapture==1.1.1 (from pip) kapture-localization==0.1.2 (from source, edb501e) Should I need to install kapture from source too?

[yocabon]

Yes, it's better to use commits of kapture and kapture-localization that are close in time. Both repositories evolve together. I'll push a new release to pip next week, we haven't done this in a long time.

kapture==1.1.2 (from source) kapture-localization==0.1.2 (from source) works good! Thank you :)
