6 years ago Hum... Did you re-install MLBox using pip ? The new version 0.5 does not have this problem (since I got rid of ipyparallel and I use joblib instead to parallelize jobs !)
hi @AxeldeRomblay ,
After you informed upon the fix per #16 , I did the update on my end to try it again.
I faced another issue with the complex stack trace below. Could you please advise?
