Hi @MoritzLaurer, the doc could be improved but in your notebook it looks like you have two git repos (one you create with git init, the other you clone from huggingface.co) whereas you only should have one.
Here’s a minimal Colab here: https://colab.research.google.com/drive/1TFgta6bYHte2lLiQoJ0U0myRd67bIuiu?usp=sharing
Let me know if this solves your issue.
@sgugger I think we might want to remove the “and your clone is setup with the right remote URL” clause from the doc as it seems to be more confusing than helpful, what do you think? Maybe we can also link to my Colab above as a self-contained example of how to push from a Colab notebook.
