Some issues encountered in reproduces the code

Hello, I encountered the following issue while trying to reproduce your code:

The error seems to occur in the initialization of BARTModel.from_pretrained in inference.py and the issue is TypeError: expected str, bytes or os.PathLike object, not NoneType:

self.bart = BARTModel.from_pretrained(
self.stage_cfg.trainer_output_folder,
checkpoint_file='checkpoints/checkpoint_best.pt',
data_name_or_path="./bin",
)

Question 1: Do you have any idea what might have caused this? How can I resolve it? Should I modify the data_name_or_path variable?
Question 2: What does the error scripts/run_AMI.sh: 19: --cuda-devices: not found mean?
Question 3: Why “2023-06-06 03:29:21 | INFO | fairseq.file_utils | Archive name 'stage_1/trainer_output' was not found in archive name list. We assumed 'stage_1/trainer_output' was a path or URL but couldn't find any file associated to this path or URL.”？

Thank you very much！
