The setup.cfg is out of date in prodigy-segment repo. Prodigy recipe in setup.cfg should be segment_fill_cache instead of segment_cache.
@samcmho Thanks for flagging!
I've opened a PR to address this and to make minor additional changes to the plug-in. I'll follow up once merged.
@samcmho Thanks for your patience! Your comment has been addressed and has been merged into the main branch.
Just to update that we have just released version 0.1.1 of the plugin with the fix.
