Hi @cosmo3769, can you please tell how did you build the ipynb notebook? Is there any template to follow? Thanks

[cosmo3769]

Hi @Bhavay-2001, I followed this notebook by @sayakpaul which he has mentioned in his PR here.

General steps I followed:

• pip install your branch (wherever you have made changes in your training script).
• import dependencies as required (generally it will be similar as given in the notebook).
• copy your save_model_card() that you updated in your training script and paste it.
• Then use some dummy data to call your save_model_card.
• Also last step will require your HF_TOKEN which you can add in your secret in colab. This is required else it won't run.
• This will create README.md file and some images.
• Go to HF and create a new model with suitable name (test-model-card-template-script-name).
• Upload all the files to HF generated in colab.
• The README.md file when uploaded will generate the model card.
• Also, upload your colab there as well.

Hope it helps!
