Download all files of a repo.

Downloads a whole snapshot of a repo’s files at the specified revision. This is useful when you want all files from a repo, because you don’t know which ones you will need a priori. All files are nested inside a folder in order to keep their actual filename relative to that folder.

An alternative would be to just clone a repo but this would require that the user always has git and git-lfs installed, and properly configured.

Raises the following errors:

Download from a given URL and cache it if it’s not already present in the local cache.

Given a URL, this function looks for the corresponding file in the local cache. If it’s not there, download it. Then return the path to the cached file.

Raises the following errors:

huggingface_hub.hf_hub_url

< >

( repo_id: str filename: str subfolder: typing.Optional[str] = None repo_type: typing.Optional[str] = None revision: typing.Optional[str] = None )

Parameters

  • repo_id (str) — A namespace (user or an organization) name and a repo name separated by a /.
  • filename (str) — The name of the file in the repo.
  • subfolder (str, optional) — An optional value corresponding to a folder inside the repo.
  • repo_type (str, optional) — Set to "dataset" or "space" if uploading to a dataset or space, None or "model" if uploading to a model. Default is None.
  • revision (str, optional) — An optional Git revision id which can be a branch name, a tag, or a commit hash.

Construct the URL of a file from the given information.

The resolved address can either be a huggingface.co-hosted url, or a link to Cloudfront (a Content Delivery Network, or CDN) for large files which are more than a few MBs.

Example:

>>> from huggingface_hub import hf_hub_url

>>> hf_hub_url(
...     repo_id="julien-c/EsperBERTo-small", filename="pytorch_model.bin"
... )
'https://huggingface.co/julien-c/EsperBERTo-small/resolve/main/pytorch_model.bin'

Notes:

Cloudfront is replicated over the globe so downloads are way faster for the end user (and it also lowers our bandwidth costs).

Cloudfront aggressively caches files by default (default TTL is 24 hours), however this is not an issue here because we implement a git-based versioning system on huggingface.co, which means that we store the files on S3/Cloudfront in a content-addressable way (i.e., the file name is its hash). Using content-addressable filenames means cache can’t ever be stale.

In terms of client-side caching from this library, we base our caching on the objects’ entity tag (ETag), which is an identifier of a specific version of a resource [1]_. An object’s ETag is: its git-sha1 if stored in git, or its sha256 if stored in git-lfs.
