Are you sure you are up to date ?

On dev branch, division by zero are already handled : https://github.com/ucoin-io/cutecoin/blob/dev/src/cutecoin/core/community.py

I have deleted the repo, cloned it again, git checkout dev. The interface seems better. But, I still have division by zero in the terminal.

It's when you run main, or when you build cutecoin ?

When I run the main file.
