When training my Token-Classification model i get this error:

HTTPError: 400 Client Error: Bad Request for url: [https://huggingface.co/api/repos/create](https://huggingface.co/api/repos/create) - Only regular characters and ‘-’, ‘\_’, ‘.’ are accepted. ‘–’ and ‘…’ are forbidden. ‘-’ and ‘.’ cannot start or end the name. The name cannot end with “.git”. Max length is 96.

I use the Notebook for Token-Classification on: _model\_checkpoint = “tbosse/bert-base-german-cased-finetuned-subj\_preTrained\_with\_noisyData”_

The error happens when trying to pass everything to a Trainer:

```auto
trainer = Trainer(
    model,
    args,
    train_dataset=tokenized_datasets["train"],
    eval_dataset=tokenized_datasets["validation"],
    data_collator=data_collator,
    tokenizer=tokenizer,
    compute_metrics=compute_metrics
)

```

```auto

There seems to be a similar Topic:

[Fine-tune a model on translation: - Beginners - Hugging Face Forums](/static-proxy?url=https%3A%2F%2Fdiscuss.huggingface.co%2Ft%2Ffine-tune-a-model-on-translation%2F8443%2F6)

I already tried removing the “/” from the model\_checkpoint, that only created different errors.

Welcome to Hugging Face Forum 🤗

I checked on Hub and saw you were able to create repository which was your problem. Was it solved?

No, i still have the same problem. Those repositories were created when changing the model\_checkpoint to “bert-base-german-cased”, to see if that seemed to be the problem.

The issue is resolved. I changed the name in TrainingArguments to make sure there is no “/” in the name and now it works.
