I’m following the instructions of Indy-vdr to use its python wrapper. It says:

The Python wrapper is located in wrappers/python/indy_vdr. In order
for the wrapper to locate the shared library, the latter may be placed
in a system shared library directory like /usr/local/lib.

I added the contents of the folder wrapper/python/ in the folder /usr/local/ib/python3.8/dist-packages, which is in my system patch:

python3.8 -c "import sys; print(sys.path)"
['', '/usr/lib/python38.zip', '/usr/lib/python3.8', '/usr/lib/python3.8/lib-dynload', '/home/ubuntu/.local/lib/python3.8/site-packages', '/usr/local/lib/python3.8/dist-packages', '/usr/lib/python3/dist-packages']

And the files are:

ubuntu@indy1:/usr/local/lib/python3.8/dist-packages$ ls
demo  indy_vdr  readme.md  setup.cfg  setup.py

When I try to run the demo, or a simple code to get its version I get an error that indy_vdr was not found. But the weird part is that I can do import indy_vdr, and it imports correctly. but I can’t do anything else:

Demo:
