ImportError: numpy.core.multiarray failed to import问题

这几天配置python的虚拟环境numpy总是回报错，保存内容如下：

 ** On entry to DGEBAL parameter number  3 had an illegal value
 ** On entry to DGEHRD  parameter number  2 had an illegal value
 ** On entry to DORGHR DORGQR parameter number  2 had an illegal value
 ** On entry to DHSEQR parameter number  4 had an illegal value
ImportError: numpy.core.multiarray failed to import
Traceback (most recent call last):
  File "<stdin>", line 1, in <module>
  File "D:\tools\python\conda\envs\cvpr\lib\site-packages\cv2\__init__.py", line 3, in <module>
    from .cv2 import *
ImportError: numpy.core.multiarray failed to import
>>> exit()

发现问题主要出现在新版本的numpy上，1.19.4版本
安装老版本的numpy即可解决问题

pip install numpy==1.18.1
