catt not installed

[bin101]

I tried to use this on my ha core installation running inside lxc on my proxmox host.

Followed the README so far but catt doesn't seems to be installed correctly:

Even after switching into the pyenv and installing catt manually via pip it still shows the same error FileNotFoundError: [Errno 2] No such file or directory: 'catt'.
Any idea?
