Problem on Loading MatchZoo Rankers

[albertoueda]

Perhaps it is a MatchZoo issue.

Code:

import pyterrier as pt
if not pt.started(): 
    pt.init(tqdm='notebook')
import onir_pt

Log:

Problem solved! Found the recommended command at matchzoo.py:
pip install matchzoo-py==1.0

Previously I had tried to update via:
pip install --upgrade git+https://github.com/NTMC-Community/MatchZoo.git'
, but it did not solve the problem.

Not sure if it was related, but I had a previous version of matchzoo (2.2.0) installed, not matchzoo-py. Perhaps we need an entry in requirements.txt?

Sounds good- thanks!

Just to be clear-- matchzoo-py==1.0 worked, correct?

Yes!

I think rather than adding it to the requirements.txt (which would mean it's required for all installations of OpenNIR), I'll add a check in matchzoo.py to see that it's a supported version (using matchzoo.__version__) & print a message if it's not. Does this sound okay?

[albertoueda]

It sounds great :)
