@aenlemmea the test looks good, could you run the black formatter as well as described here https://github.com/cleanlab/cleanvision/blob/main/DEVELOPMENT.md#how-to-style-new-code-contributions

[aenlemmea]

I made sure to run the command before submitting the PR and oddly enough running it again changed nothing. So I tried installing BlackConnect (on Pycharm) and it did change the formatting now.
