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) 1093 logger.info(result.stdout) 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?
