hey @wkd88 that's correct, would you want to give it a shot in a quick PR?

here's the file that needs to be updated: https://github.com/Lightning-AI/pytorch-lightning/blob/master/src/lightning/fabric/cli.py

Hi @lantiga I want to try a PR on this issue.

I’ve updated the file to include the "auto" option for the accelerator. You can find the PR here: #20473 .
