python - python-opencv-headless 的问题

Question

我曾经使用conda yml文件在我的服务器上安装opencv，如下所示

name: project_environment
dependencies:
- python=3.6.2
- pip=20.2.4

- pip:
  - pillow
  - numpy
  - opencv-python-headless==4.5.3.56
  - torch
  - torchvision
  - face-alignment==1.3.4
  - tensorflow==2.5.0
  - cmake
  - dlib
  
channels:
- anaconda
- conda-forge

之前，它可以正常工作，但是昨天我运行脚本时，出现错误

from .cv2 import *
ImportError: libGL.so.1: cannot open shared object file: No such file or directory

如果我安装 python-opencv，而不是 headless 版本，应该会出现此错误。 我该如何调试，哪个包导致了问题。

谢谢skvark 。将您的建议作为答案发布以帮助其他社区成员。

Other alternative is to run sudo apt-get install -y libgl1-mesa-dev which will provide the missing libGL.so.1 if you want to use opencv-python. The libgl1-mesa-dev package might be named differently depending on your GNU/Linux distribution.

您可以引用Error trying to import cv2(opencv-python) package , ImportError: libGL.so.1: cannot open shared object file: No such file or directory和 ImportError: libGL.so.1: cannot open shared object file: No such file or directory
