"libGL.so.1: cannot open shared object file: No such file or directory" problem solved

---

foreword

When using Docker to build a deep learning environment, such an error occurs after installing opencv-python, so I am looking for a solution.

1. Basic concepts

Try installing opencv-python-headless instead of opencv-python, which is suitable for headless systems such as Docker.

2. Operation steps

pip install opencv-python-headless

opencv-python: This repository contains only the main modules of the OpenCV library.
opencv-contrib-python: The opencv-contrib-python library contains main modules and contrib modules.
opencv-python-headless: Same as opencv-python but without GUI functionality. Suitable for interfaceless systems.
opencv-contrib-python-headless: Same as opencv-contrib-python, but without GUI functionality. Suitable for interfaceless systems.
