# Describe the bug
I have been getting the following error message when I am pushing my model in unit2 handson on colab using push_to_hub function define in the notebook
---------------------------------------------------------------------------

The above exception was the direct cause of the following exception:

# NOTE
I used the write token from my Hugging Face account and logged in using the notebook.login() command as mentioned in the hands-on guide.

Additionally, while installing the project dependencies, I encountered an error related to pickle5. I believe this issue arises because pickle5 requires Python versions between 3.7 and 3.8, which may not match the current environment.
