记录Ubuntu报错:qt.qpa.plugin: Could not load the Qt platform plugin "xcb" in "/usr/local/lib/python3.6/dist-packages/cv2/qt/plugins" even though it was found
- 原因是你的python中opencv版本过高将opencv-python版本 由 4.5 下降为 4.3.0.36
pip3 install opencv-python==4.3.0.36
- 报错：
ImportError: libSM.so.6: cannot open shared object file: No such file or directory
