Deprecated `upload_file` command in the NLP course

[tinosai]

This link details a method to submit files to one's HF repo using the huggingface_hub.upload_file function.

from huggingface_hub import upload_file

upload_file(
    "<path_to_file>/config.json",
    path_in_repo="config.json",
    repo_id="<namespace>/dummy-model",
)

This is however not working as of version 0.26.2. Please replace the code with the newer syntax explained here:

from huggingface_hub import HfApi
api = HfApi()
api.upload_file(
    path_or_fileobj="<path_to_file>/config.json",,
    path_in_repo="config.json",
    repo_id="<namespace>/dummy-model",
)

Thank you!
