Hi! Should work fine with clingo5.5.

Installing with pip should install the correct clingo version. How did you install? Is it possible that xclingo is trying to use your local (5.4) clingo installation instead of the python package?

[Liquid-Aristocracy]

Hmm, I installed with pip. That clingo is indeed installed with the gringo deb package, but after I removed gringo and reinstalled xclingo, I still have the same error.

On a side note, my friend has the same issue and they have clingo 5.7.1.

Any updates on this?

I have clingo 5.5.2 from conda and still gives the error:

Hi, I am getting the same issue with clingo 5.5.0, 5.5.1 and 5.5.2.
Which is the correct one?
