Bug in myfm.MyFMOrderedProbit() model

[RafaelSterzinger]

Hello Tomoki Ohtsuki,
I was following your ml-100k-extended exemplary notebook, but had problems running the myfm.MyFMOrderedProbit() model with use_date=False. The fitting works fine, but the problem arises during prediction. I tried to attach a screenshot of the error I get. I hope it worked. If not, the error I am getting is "ValueError: Relation blocks have inconsistent mapper size with case_size". In your notebook, if the use_date=False is set, then X is set to None and X_rel=test_blocks. The error message is based on this set None value. However, in the myfm.MyFMRegressor() model everything works as expected.

Thanks in advance for your help!

Hi @RafaelSterzinger, thank you for reporting the issue and sorry for the late reply.
I could reproduce it and identified the problem!
I believe the latest commit 661037c
has fixed the issue, and I will soon make a release for the fix.

Thank you again for your help!

It took a very long time, but I could release the version 3.1.0 with the bug fixed.
