從x86_64 + ubuntu18.04 + python3.5中import cv2(opencv4.1), 遇到以下錯誤：
ImportError: libSM.so.6: cannot open shared object file: No such file or directory ImportError: libXrender.so.1: cannot open shared object file: No such file or directory ImportError: libXext.so.6: cannot open shared object file: No such file or directory
ImportError: libgthread-2.0.so.0: cannot open shared object file: No such file or directory
解決方案：
apt-get update apt-get install libsm6 apt-get install libxrender1
apt-get install libglib2.0-dev apt-get install libxext-dev
