Xgboost - How to use feature_importances_ with XGBRegressor()?
from xgboost import XGBClassifier
model = XGBClassifier.fit(X,y)

# importance_type = ['weight', 'gain', 'cover', 'total_gain', 'total_cover']
model.get_booster().get_score(importance_type='weight')


However, the method below also returns feature importance's and that have different values to any of the "importance_type" options in the method above. This was raised in this github issue, but there is no answer [as of Jan 2019].
