Fatal: Authentication failed

Hello Everyone,
While trying to run the following:
from transformers import Seq2SeqTrainer

trainer = Seq2SeqTrainer(
model,
args,
train_dataset=tokenized_datasets[“train”],
eval_dataset=tokenized_datasets[“test”],
data_collator=data_collator,
tokenizer=tokenizer,
compute_metrics=compute_metrics_1
)

I am getting the following error:
CalledProcessError Traceback (most recent call last)
/usr/local/lib/python3.7/dist-packages/huggingface_hub/repository.py in git_pull(self, rebase, lfs)
1090 command,
→ 1091 self.local_dir,
1092 )

5 frames
CalledProcessError: Command ‘[‘git’, ‘pull’]’ returned non-zero exit status 1.

During handling of the above exception, another exception occurred:

OSError Traceback (most recent call last)
/usr/local/lib/python3.7/dist-packages/huggingface_hub/repository.py in git_pull(self, rebase, lfs)

1094 except subprocess.CalledProcessError as exc:
→ 1095 raise EnvironmentError(exc.stderr)
1096
1097 def git_add(

OSError: fatal: Authentication failed

Can someone assist to identify the reason for failure?
Thanks,
Andy
