After making these changes locally, which resolved the ZeroDivisionError: division by zero for me, and running the test_trainer locally passed, but it fails on the CI. I'll mark the PR as a draft to investigate further.

Hello @AngieMeliss, I was working on other issues, and since the updates I made weren't the relevant solution for the issue I was targeting, it required me to delve further into the cause of the failing test. I may be slow on that since I'm focusing on another issue, so I closed it so someone else can work on it. 🙂
