python3调用opencv问题解决
问题描述：
Traceback (most recent call last): File “screenshot.py”, line 15, in <module> import cv2 File “/usr/local/lib/python3.7/dist-packages/cv2/__init__.py”, line 3, in <module> from .cv2 import *ImportError: libQtGui.so.4: cannot open shared object file: No such file or directory
解决方案:
pip3 install opencv-python
sudo pip3 install opencv-contrib-python
sudo apt-get install libhdf5-dev
sudo apt-get install libqtgui4
sudo apt-get install libqt4-test
可能还有其它缺失的，缺啥，装啥。
