I ran the example code from you GitHub page and after trying to train the classifier:

learner$train(task, row_ids = 1:120)

I got the following error message:

Error in lightgbm::lgb.prepare(data) : lgb.prepare() was removed in LightGBM 3.0.0. Please use lgb.convert_with_rules()

This seems to be the problem:

prepare data for lightgbm

  data = lightgbm::lgb.prepare(data)

Replacing with data = lightgbm::lgb.convert_with_rules(data) should fix this ?
