pycharm无法正确导出包中的库函数是为啥？

```D:\python.exe D:/Python3.6/MedicalNamedEntityRecognition-master/lstm_train.py
Traceback (most recent call last):
File "D:-master/lstm_train.py", line 7, in
import numpy as np
ModuleNotFoundError: No module named 'numpy'

明明已经安装了这个库，为什么还是报错说没有这个库

检查下File->Settings里面配置的python解释器版本是否和你装模块时python版本一致
