Oh yes saw the PR - thanks for your contribution!

Glad you found the solution - sorry I couldn't help much

@LostRuins Apologies on the delay - it seems like it's saying the labels are nested? Would it be possible to print out maybe the first few rows of `trainer.train_dataset`? Thanks!...

Ok I'll check on my end and get back to you asap!

That most likely means your computer doesn't have CUDA - try installing cudatoolkit

Oh my it seems like maybe all of torch might be broken :(

Ie Conda is not recognising the correct CUDA path

Working on it!

Thanks! Oh this is for the nightly release of TRL right? Would it be possible to first check whether `self._metrics["completion_length"]` exists, and or `self._metrics["train"] / "eval"` exists to allow older...

Very good work thanks!
