cc @osanseviero with a potential TODO for @Wauplin :)

hmm I think we can't use the duplicate api for models/datasets yet? @Sylvestre

also ping @Sylvestre for a quick review as you implemented the feature 😁

hmm @coyotte508 yes i think so

It looks ok to me

Hey @julien-c , I just took over your code and added build_hf_headers(token=token) to create the request headers. Also made use of hf_raise_for_status(r) instead of handling the error manually. Both helpers are exposed under huggingface_hub.utils.

Copy-pasting the code here instead of creating a new PR to keep track of the discussion in a single place. Would be good to edit suggestions in the HF PRs but I guess that will come :)

# app.py
import gradio as gr
import requests
from huggingface_hub import whoami
from huggingface_hub.utils import build_hf_headers, hf_raise_for_status

ENDPOINT = "https://huggingface.co"
# ENDPOINT = "http://localhost:5564"

REPO_TYPES = ["model", "dataset", "space"]


def duplicate(source_repo, dst_repo, token, repo_type):
    try:
        if not repo_type in REPO_TYPES:
            raise ValueError("need to select valid repo type")
        _ = whoami(token)
        # ^ this will throw if token is invalid

        r = requests.post(
            f"{ENDPOINT}/api/{repo_type}s/{source_repo}/duplicate",
            headers=build_hf_headers(token=token),
            json={"repository": dst_repo},
        )
        hf_raise_for_status(r)

        repo_url = r.json().get("url")

        return (
            f'Find your repo <a href=\'{repo_url}\' target="_blank" style="text-decoration:underline">here</a>',
            "sp.jpg",
        )

    except Exception as e:
        return (
            f"""
        ### Error 😢😢😢
        
        {e}
        """,
            None,
        )


interface = gr.Interface(
    fn=duplicate,
    inputs=[
        gr.Textbox(placeholder="Source repository (e.g. osanseviero/src)"),
        gr.Textbox(placeholder="Destination repository (e.g. osanseviero/dst)"),
        gr.Textbox(placeholder="Write access token"),
        gr.Dropdown(choices=REPO_TYPES, value="model"),
    ],
    outputs=[
        gr.Markdown(label="output"),
        gr.Image(show_label=False),
    ],
    title="Duplicate your repo!",
    description="Duplicate a Hugging Face repository! You need to specify a write token obtained in https://hf.co/settings/tokens. This Space is a an experimental demo.",
    article="<p>Find your write token at <a href='https://huggingface.co/settings/tokens' target='_blank'>token settings</a></p>",
    allow_flagging="never",
    live=False,
)
interface.launch(enable_queue=True)

I am also in favor of exposing a modified requests module from huggingface_hub to wrap HTTP calls, add the header properly and monkeypatch the raise_for_status method. I have created an issue on huggingface_hub repo for it.

Ah for some reason i was under the impression hf_raise_for_status and build_hf_headers were not exposed from the library! Ok, it's easy then. Thanks

You cannot push directly on this PR due to permissions, correct?

Exactly. I tried and got a 403 forbidden:

>>> from huggingface_hub import upload_file
>>> upload_file(path_or_fileobj="app.py", path_in_repo="app.py", repo_id="osanseviero/repo_duplicator", repo_type="space", revision="refs/pr/3")

(...)

And actually passing create_pr=1 doesn't work either. But from a workflow perspective, idk if we want to be able to create a PR against another PR.

not for now, probably

Ok I pushed your change (f4326699). Thanks!

@osanseviero this should be ready to merge now :)

Thanks a lot everyone!
