It seems that either I installed the incompatible version of a library, or an incompatible library came with the preinstalled cloud image?
What is funny is that I tried to install only py dependencies available by 2023-06-22, which was the date of the last commit on requirements.txt, using pypi-timemachine, but it seems I still failed somewhere. Here are the versions on my cloud machine:

Does any of you good souls know what is wrong and which library and version is causing a problem?
I tried to reproduce the complete example on a Hyperstack cloud machine (A100-80G-PCIe, OS Image Ubuntu Server 22.04 LTS, R535 CUDA 12.2). Since using a single A100, I reduced the batch size, this command starts the training:
python -u train.py model=pythia28 datasets=[hh] loss=sft exp_name=anthropic_dpo_pythia28 gradient_accumulation_steps=2 batch_size=16 eval_batch_size=16 trainer=FSDPTrainer sample_during_eval=false model.fsdp_policy_mp=bfloat16Unfortunately, training fails when saving at the first checkpoint at 20000 examples with stack trace:
