Hey @VukW, can you give some insight on why this error is coming up? I am unable to reproduce any changes on my local system:

(venv_gandlf) PS C:\Projects\GaNDLF> black .\gandlf\cli\data_split_saver.py
All done! ✨ 🍰 ✨
1 file left unchanged.

Hi @scap3yvt , Added a fix linter requires. For local reproducing, may you check your black version matches CI one? It should be 23.11.0:

pip list | grep black
