When I use FSDPtrainer, I met a Bus error

[Red-Scarff]

my command is below:

python -u train.py model=pythia69 datasets=[hh] loss=sft exp_name=anthropic_dpo_pythia69 gradient_accumulation_steps=2 batch_size=64 eval_batch_size=32 trainer=FSDPTrainer sample_during_eval=false

and I met an error, the log is like that:

warnings.warn('resource_tracker: There appear to be %d '
Bus error

So can anyone help me to solve this? I didn't make any change to this repo, I just clone it and run the command. If you need more info, please contact me, I really need your help, and thanks for giving me a hand.
