Hi, thanks for opening this issue. It appears that one of our dependencies (qpsolvers) is not installing. I was able to replicate the issue on my system.

Until this is fixed, you could install avalanche by downloading the repo, removing qpsolvers from requirements.txt, and then running pip install -e ".. This works as long as you don't need GEM, which is the only method using qpsolvers.

Alternatively, the install should still work with python<3.12.
