I am using python 3.4 and have installed catboost library but when i try to import, it shows the following error.

ImportError                               Traceback (most recent call last)
c:\python34\lib\site-packages\catboost\core.py in <module>()
 17 try:
---> 18     from _catboost import _PoolBase, _CatBoostBase, CatboostError, 
_cv, _set_logger, _reset_logger
 19 except ImportError:

ImportError: No module named '_catboost'

During handling of the above exception, another exception occurred:

ImportError                               Traceback (most recent call last)

Because you're using python 3.x you need to use

pip3 install catboost

not

pip install catboost

Try uninstall cleanly and re-install catboost again. I fix that error by this.
