I'm also interested in using Python to call Csound, as part of a Reinforcement Learning and Q learning project that is written in Python. When I try to execute the first call in the Jupyter notebook "01-the-ctcsound-module.ipynb" I get this error: 

----> 1 libcsound = ct.CDLL("libcsound64.so")
OSError: libcsound64.so: cannot open shared object file: No such file or directory

My libcsound64.so.6.0 is in here:

ls /usr/lib64/libcs*.*
/usr/lib64/libcsound64.so.6.0

The libsound request works if I change the name of the module to include the 6.0 in the name. 

libcsound = ct.CDLL("libcsound64.so.6.0")
returns True

Is there something I'm doing wrong? 

This is a recent install of csound in linux using "sudo yum install csound". Csound works, and says that it is version 6.
--Csound version 6.16 (double samples) Aug 10 2021

Any advice is appreciated.

I think you are just missing the symlink. Some linux distros only install these with the dev packages. You could either create the symlink yourself or install csound-dev (or whatever it is called).
