如何在Docker（Azure Web App）中为Python导入cv2？

Question

The error that is displayed is:

...

I found resources online that say I need to run ( ImportError: libSM.so.6: cannot open shared object file: No such file or directory )

But on the Azure Platform, once the deployment isnt running, it isnt possible to connect to the web SSH. So how do I fix this issue of importing cv2?

Answer 1

I think you need the dependency package to proper install and also it needs the scikit-image==0.15.0

pip install opencv-contrib-python

pip install opencv-python
