On which platform/distro?

[yamadharma]

linux gentoo python-3.5 python-3.6

[yamadharma]

cadabra2-2.2.0 works without problems.

What happens if you just run

 cadabra-server

from the command line?

Can confirm the same problem on manjaro using aur cadabra2-git package.

It's unfortunately a fairly generic error message so I'll need to get one of these distros installed somewhere.

After commit https://github.com/kpeeters/cadabra2/commit/3b121a977977838e40113181fbc4d41dad273a51 it's work for me.

Ah, thanks. That commit was meant to fix an issue on macOS, but since it involved some pybind simplifications I was hoping this would perhaps also solve the issue you reported. Forgot to ask you to re-test. Very good, will close the issue.
