Python:如何在谷歌云功能上安装OpenCV

Question

我使用的是谷歌云功能Gen2和Python 3.10以及最新版本的gcloud-cli和opencv-python==4.6.0.66和functions-framework==3.2.0

我无法在谷歌云上部署，因为import cv2导致了这个错误

ImportError: libGL.so.1: cannot open shared object file: No such file or directory

at .<module> ( /layers/google.python.pip/pip/bin/functions-framework:8 )

如果我使用opencv-python-headless，我会得到这个错误

ImportError: Unable to find zbar shared library

OpenCV是必备的要求。这个错误可以修复吗？还是应该将项目部署到其他地方？

问题的总结

libgl的第一个错误可以通过安装opencv-python headless(这只是CPU，不需要libgl(来解决

pyzbar同样需要安装zbar。(在云功能环境中无法完成(
