RuntimeError: main thread is not in main loop

[alexandrebrilhante]

Using the README's example, a simple AutoML pipeline seems to fail and not go all the way:

Create directory AutoML_1
AutoML task to be solved: binary_classification
AutoML will use algorithms: ['Baseline', 'Linear', 'Decision Tree', 'Random Forest', 'Extra Trees', 'LightGBM', 'Xgboost', 'CatBoost']
AutoML will optimize for metric: logloss
AutoML will try to check about 74 models

@brilhana thanks for reporting! I've made a ton of new changes in the code. Can you tell me what version of mljar-supervised are you using? (How you installed it, from pip or from source?)

[pplonski]

BTW, in this package, I'm not using tkinter so your error looks very weird.

[alexandrebrilhante]

Seems to be caused by Microsoft Visual Studio's version of Python (3.7.5). Unable to reproduce this bug on Linux (Ubuntu / Centos).

@brilhana thanks for checking!

I'm also using Visual Studio. It has a nice feature to preview markdown reports that are generated from mljar-upservised.
