Detail:
I've previously used "lgb" for classification and it worked but now it doesn't seem to work for classification tasks. And if I remove the estimator_list from the automl_settings then I get a NoneType error which doesn't go away even after using the pip install flaml[automl] command as suggested by one of the answers in the issues.

Error 1: When using only LGBM

Error 2: When not defining any specific estimator

What I've tried?

  • I can use other estimators if I exclude 'lgb'. That works fine
  • I tried installing both flaml[automl] and flaml[notebook] but the problem remains
  • Tried updating the library but still no luck
  • Though I'm not stuck at this point because I'm able to use other estimators but just wanted to point out the issue

Hi @ArslanKAS , there is an estimator named lgbm, i.e., lightgbm. No estimator named lgb.

For the NonType Error, could you share the complete code for reproducing? Thanks.
