Unfortunately I also experienced this issue a few days ago and couldn't find a workaround. It must be due to some updated dependency. I will look into this more today!

Hello @Federico-PizarroBejarano, thanks for your help. I also opened an issue in the pycddlib repo and Bob suggested to follow this page with two steps (for mac system):

1. brew install cddlib gmp
2. env "CFLAGS=-I$(brew --prefix)/include -L$(brew --prefix)/lib" pip install pycddlib
   and it works for me.
   I am copying that repo issue page here for your reference.

[Federico-PizarroBejarano]

Thank you! I unfortunately already tried this and it didn't work. I am using Ubuntu 20.04. Let me know if you find a workaround!

[Federico-PizarroBejarano]

OK I seem to have a workaround. I simply removed the dependency on pytope which seems to be causing the issue. This dependency is only used in linear_mpsc.py. For now you can do this while we find a more permanent solution.

[Federico-PizarroBejarano]

Seems that pytope is installable in python 3.8 but not 3.10. No idea why. For now will raise an issue with them (although doubt they'll answer), and remove pytope from our dependencies until we can find a fix. Considering how small of a dependency it is, we may just indicate that users need to manually install pytope from source if they wish to use it.

[Federico-PizarroBejarano]

Opened a PR which fixes this in a more permanent fashion: #168. This should solve the issue.
