Script deletes files and subfolders on my machine about community-events

For sure! Thanks for reporting it! I'll have a look to see if there's a way we can avoid this in the future (potentially being more explicit in the text?)

Hey @BirgerMoell, sorry to hear that you lost some files 😥

This behaviour looks to be a combination of a couple of things:

1. The output_dir is set to ./ (i.e. the directory in which the script run.sh is saved). The README instructions suggest that you run the script from within a new model repository cloned from the Hugging Face Hub (i.e. set your current working dir to a cloned model repo). This means that the only files that can be touched by the script are those within the model repository, and any files outside the repo are safe! The Trainer is sandbox in this regard, it only has access to the files you specify in the output_dir. If you don't want Trainer to touch files in your current working dir, you need to run the script from a different dir or set output_dir accordingly.
2. This is the desired behaviour by setting overwrite_output_dir (see docs). I'm afraid we can't change this as it's required for over-riding checkpoints and flushing dirs.

So what you can do is run the script from within a new model repo or set --overwrite_output_dir=False \ in the arguments to run.sh. We're trying to give instructions that can be used by as many participants as possible. They've been stress tested when all of the instructions are run sequentially, but the behaviour will no doubt be different when different steps are run. Sorry to hear that you lost files. If this was a model repo cloned from the HF Hub could you revert to the last commit?

I got most of the stuff back through git but I seemed a bit unexpected so I just wanted to report it to make sure it behaved as it was intendent.

(It will only do a full wipe if the output dir is not a HF repo:
