Assuming you uploaded your model using the instructions in the docs 3, my suggestion would be to copy all the contents in the folder produced by saving your model
model.save_pretrained(target_name_or_path)

to the repository where you original model is stored. Then you can run
cd path/to/original/model
git add . && git commit -m "Update labels"
git push

and that should update both config.json and pytorch_model.bin. If you don’t have the repository of the original model you can just clone it again
git lfs install
git clone https://huggingface.co/MoritzLaurer/policy-distilbert-7d

HTH!
