Our install has this problem too and we're not sure why. We've been able to work around it by running:

export LD_LIBRARY_PATH=$LD_LIBRARY_PATH":/usr/lib/x86_64-linux-gnu:"

in bash before calling python. If anyone knows of a permanent solution that would be a big help but this works as a temporary fix.

Hi @michaelmooreny. You need to install openslide-python in the following way:

1. sudo apt update && apt install -y openslide-tools
2. pip install openslide-python

Then try to run the command :

import openslide

Then it will work

@Abhinav-Telukunta : How to solve this issue on Amazon Linux server(EC2). As it won't support apt
