ImportError:没有名为“_catboost”的模块

Question

我使用python3.4并安装了catboost库，但是当我尝试导入时，它会显示以下错误。

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:

Answer 1

因为您正在使用python 3.x，所以您需要使用

pip3 install catboost

不

pip install catboost

Answer 2

你可以

!pip3安装catboost

然后

从catboost进口CatBoostClassifier

Answer 3

试着卸下干净的安装，然后再重新安装catboost。我用这个修正了错误。
