Catboost: Good work in command line, but not work in ipython

[beloteloff]

import numpy as np

from catboost import CatBoostClassifier

# initialize data

train_data = np.random.randint(0, 100, size=(100, 10))

train_label = np.random.randint(0, 2, size=(100))

test_data = np.random.randint(0, 100, size=(50, 10))

# specify the training parameters 

model = CatBoostClassifier(iterations=2, depth=2, learning_rate=1, loss_function='Logloss', verbose=True)

#train the model

model.fit(train_data, train_label, cat_features=[0,2,5], verbose=True)

# make the prediction using the resulting model

preds_class = model.predict(test_data)

preds_proba = model.predict_proba(test_data)

print("class = ", preds_class)

print("proba = ", preds_proba)

ImportError: cannot import name 'CatBoostClassifier'

I installed catboost from source like you described it in instruction
Python 3.4.2
Type 'copyright', 'credits' or 'license' for more information
IPython 6.1.0 -- An enhanced Interactive Python. Type '?' for help.

When I type "python" and after that "tab", I see a several version
python
python python2.7-config python3.4m python3.5m python-html2text
python2 python2-config python3.4m-config python3.5m-config
python2.7 python3.4 python3.5 python-config
My os is Cent Os 7

Which python do u use by default (python --version)?
The problem could be that u installed CatBoost for python2.7 and trying to use it in python 3.4.
Unfortunately we have no wheel for python 3.4, so u can try to clone CatBoost from github and build wheel for your python version.

Any updates?

I had this exact issue - and the problem was I had foolishly named my program file as catboost.py.
Renaming it to something else sorted the issue for me.
