记python安装cv2
随手记
python2.7
使用安装opencv-python替换cv2
#安装:
pip install opencv-python
#安装指定版本
pip install -U opencv-python==3.4.4.19
不行的话 可以升级到python3或者另外安装python3
python3
安装python
# 我这里安装的python3.6版本 yum install python36 # 查看python版本 python3 -V # 查看pip版本 pip3 show pip # pip升级 pip3 install --upgrade pip
安装cv2
pip install cv2 # 如果以上命令失败,可试试下面一条 pip install opencv-python
调试
如果运行中遇到类似以下错误:from .cv2 import * ImportError: libGL.so.1: cannot open shared object file:
yum install libglvnd-glx
ImportError: libXrender.so.1: cannot open shared object file: No such file or directory
yum install libXrender-devel.x86_64
如果第一次执行失败,可能是opencv版本问题,可以修改opencv版本:
pip install -U opencv-python==3.4.4.19ImportError: libSM.so.6: cannot open shared object file: No such file or directory
yum install libSM-1.2.2-2.el7.x86_64
