getting zero score accuracy on test data

[jboverio]

Hi.

I am playing with ml ensemble in Kaggle but I keep getting 0 score accuracy on submission. I can't figure out what is wrong!

from mlens.ensemble import BlendEnsemble
from sklearn.linear_model import LogisticRegression
from sklearn.ensemble import RandomForestClassifier
from sklearn.svm import SVC
seed=3
def build_ensemble(proba, **kwargs):
"""Return an ensemble."""
estimators = [
SVC(probability=proba),
CatBoostClassifier(iterations=300,
logging_level='Silent', learning_rate= 0.03, depth=5)]

ensemble = BlendEnsemble(**kwargs)
ensemble.add(estimators, proba=proba)   # Specify 'proba' here
ensemble.add_meta(LogisticRegression())

return ensemble

ensemble_false = build_ensemble(proba=False)
ensemble_false.fit(X_, Y)
#preds_false = ensemble_false.predict(X_)
#print("Accuracy:\n%r" % accuracy_score(preds_false, Y))

ensemble = build_ensemble(proba=True)
ensemble.fit(X_, Y)
#preds = ensemble.predict(X_)
#print("\nAccuracy:\n%r" % accuracy_score(preds, Y))

Xtest = pd.read_csv('../input/labdata-churn-challenge-2020/test.csv')

X_test_ = feat_engineering_types(Xtest)
X_test_2 = trata_na(X_test_)
X_test_3 = coloca_dummy(X_test_2)
predicted_prices_false = ensemble_false.predict(X_test_3)

my_submission_false = pd.DataFrame({'id': Xtest.id, 'Churn': predicted_prices_false})

my_submission_false.to_csv('submission.csv', index=False)
predicted_prices = ensemble.predict(X_test_3)

my_submission2 = pd.DataFrame({'id': Xtest.id, 'Churn': predicted_prices})

my_submission2.to_csv('submission2.csv', index=False)
