lightgbm - AttributeError：模块“lightgbm”没有属性“LGBMClassifier”

Question

我安装了lightgbm conda install -c creditx lightgbm=0.2.0，并且导入lightgbm成功，但是当我导入LGBMClassifier或使用LGBMClassifier它时失败。

错误是：

<module 'posixpath' from '/usr/anaconda3/lib/python3.5/posixpath.py'>
Traceback (most recent call last):
  File "/root/Final_Contest/ligGBM.py", line 12, in <module>
    gbm = lgb.LGBMClassifier(objective='binary',num_leaves=31,learning_rate=0.1,n_estimators=3000)
AttributeError: module 'lightgbm' has no attribute 'LGBMClassifier'

可能是什么情况？
