opencv安装递归

Question

我使用Ubuntu (18.04.3LTS)和Python使用Anaconda。我正在尝试安装opencv，并且我遵循了安装教程。但当我打字时：

    import opencv
    import cv2

我得到：

['/home/amyuval', '/home/amyuval/anaconda3/lib/python37.zip', '/home/amyuval/anaconda3/lib/python3.7', '/home/amyuval/anaconda3/lib/python3.7/lib-dynload', '', '/home/amyuval/anaconda3/lib/python3.7/site-packages', '/home/amyuval/anaconda3/lib/python3.7/site-packages/IPython/extensions', '/home/amyuval/.ipython']

ImportError Traceback (most recent call last)
<ipython-input-3-c8ec22b3e787> in <module>
     1 import cv2

~/anaconda3/lib/python3.7/cv2/__init__.py in <module>
     87     if DEBUG: print('OpenCV loader: DONE')
     88 
     89 bootstrap()

~/anaconda3/lib/python3.7/cv2/__init__.py in bootstrap()
     21     if hasattr(sys, 'OpenCV_LOADER'):
     22         print(sys.path)
     23         raise ImportError('ERROR: recursion is detected during loading of "cv2" binary extensions. Check OpenCV installation.')
     24     sys.OpenCV_LOADER = True
     25 

ImportError: ERROR: recursion is detected during loading of "cv2" binary extensions. Check OpenCV installation.

有什么问题吗？

Answer 1

在Windows/MinGW上，我也遇到了一个递归问题(但没有链接到OpenCV_LOADER)。

下面的技巧(在Python安装上，而不是在MSys2 one.)：

pip3 install opencv-python --upgrade --force-reinstall # [--user]
