xgboost python does not display information even when silent = False

[Wenchao-Yang]

I am using xgboost to train a model. I want it to print out some info about training process. However, it does not give me anything even if silent = False.

import xgboost as xgb
xgbc = xgb.XGBClassifier(
   gamma=0.1, learning_rate=0.05, max_delta_step=0, max_depth=8,
   min_child_weight=6, missing=None, n_estimators=250, nthread=8,
   objective='binary:logistic', reg_alpha=0, reg_lambda=1,
   scale_pos_weight=1, seed=0, silent=False, subsample=0.9)
xgbc.fit(X, y)

With Jupyter did you check the console where you launched Jupyter? No output was printed to the Jupyter notebook for me but there was some in the console. Also using Python 3 on Windows 10.
