### Reproduction

I was setting up and using Galactica language model. 
Was facing this error: 
**ValueError: Both `max_new_tokens` and `max_length` have been set but they serve the same purpose -- setting a limit to the generated output length. Remove one of those arguments. Please refer to the documentation for more information.** 

```
!pip install galai
import galai as gal
from galai.notebook_utils import *
```

`model = gal.load_model("base")
`
`model.generate("The Transformer architecture [START_REF]") ` ----- here the error came up.


Same error came up while running this ---- 
```
prompt = f"Question: A bat and a ball cost $\\$1.10$ in total. The bat costs $\\$1.00$ more than the ball. How much does the ball cost?\n\nAnswer:"
display_markdown(model.generate(prompt, new_doc=True, max_length=250))
```

### Expected behavior

these are the expected results. Please help.
Hi @arastumudgal 
If I am not mistaken, the fix should have been addressed in https://github.com/huggingface/transformers/pull/21347
If you install `transformers` from the `main` branch `pip install git+https://github.com/huggingface/transformers`, your script should work
<|||||>Hi @younesbelkada 

`
ImportError: IProgress not found. Please update jupyter and ipywidgets. See https://ipywidgets.readthedocs.io/en/stable/user_install.html`


I am facing this error on jupyter notebook when loading the models.

```
!pip install -U ipywidgets
!pip install ipywidgets --upgrade
!jupyter nbextension enable --py widgetsnbextension
!pip install -U jupyter
```


Did this too but still it isnt working, showing the same error. Any fix? It is working on google colab but not on jupyter notebook. <|||||>Hi @arastumudgal 
Thanks for the issue but this looks like an issue that is independent from `transformers` <|||||>> Hi @arastumudgal If I am not mistaken, the fix should have been addressed in #21347 If you install `transformers` from the `main` branch `pip install git+https://github.com/huggingface/transformers`, your script should work



Just tried this, facing the same error though. @younesbelkada <|||||>@arastumudgal Maybe an update flag was missing, i.e. `pip install -U git+https://github.com/huggingface/transformers` :) 

Please note that `galai` [has a pinned transformers version](https://github.com/paperswithcode/galai/blob/e3e34481aefeceff9f239f2121988566382a72b2/requirements.txt#L2), and you might run into other issues.<|||||>This issue has been automatically marked as stale because it has not had recent activity.
