from sklearn.ensemble import RandomForestClassifier
pool_classifiers = RandomForestClassifier()
pool_classifiers.fit(X_train, y_train)
from deslib.des.meta_des import METADES
from sklearn.linear_model import LogisticRegression
meta_classifier = LogisticRegression()
clf = METADES(pool_classifiers, meta_classifier=meta_classifier) 
clf.fit(X_dsel, y_dsel)

@s0rel Hello,

This is a bug that was fixed in recent patches. In order to fix that you need to install the latest version of the library using the following command:

pip install git+https://github.com/scikit-learn-contrib/DESlib -U

That will install the current development version which has several bug fixes since version version 0.3 release
