ImportError: numpy.core.multiarray failed to import

您好，我在使用FaceTools工具对人脸数据库进行对齐处理时，遇到下面的问题：
ImportError: numpy.core.multiarray failed to import

Traceback (most recent call last):
  File "D:\facealign\FaceTools-master\main.py", line 18, in <module>
    import aligment
  File "D:\facealign\FaceTools-master\aligment.py", line 8, in <module>
    import cv2
ImportError: numpy.core.multiarray failed to import
请问该怎么解决？
