python - opencv安装递归

问题描述

我正在为 Python 使用 Ubuntu (18.04.3LTS) 和 Anaconda。我正在尝试安装opencv，并按照安装教程进行操作。但是当我输入：

    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.

可能是什么问题呢？

解决方案

在 Windows/MinGW 上，我也遇到了递归问题（但未链接到OpenCV_LOADER）。
以下是诀窍（在 Python 主安装上，但不是在 MSys2 上......）：

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