[Q] Is there any `direct_url` to existing artifact files?

As of the File System, we can easily retrieve the direct_url of a file uploaded to a wandb run, pointing to the Google Storage URL as follows:

import wandb
api = wandb.Api()
file = api.run(f"{entity}/{project}/{run_id}").file(name=file_path)
file.direct_url

Is there any way to actually retrieve the URL to the Google Storage for the Artifact Store files? If not, can it be implemented?

import wandb
api = wandb.Api()
artifact = api.artifact(name=f"{entity}/{project}/{artifact_name}:{artifact_version}", type=artifact_type)
file = artifact.get_path(name=file_path)
file.direct_url

Thanks in advance! 😄

Excellent! Thanks for posting this solution @alvarobartt. I also post an alternative option for future reference. Please let me know if that wouldn’t work for you.

import wandb
import base64

api = wandb.Api()
artifact = api.artifact(
  name="wandb/yolo-chess/run_1dnrszzr_model:v8",
  type="model",
)
id = artifact.id
hid = wandb.util.b64_to_hex_id(artifact._load_manifest().entries["last.pt"].digest)
print(f"https://api.wandb.ai/artifactsV2/gcp-us/{artifact.entity}/{id}/{hid}")

Hi @alvarobartt thanks for the additional context. Since you’re interested only to specific filename you could then replace your last two lines with something like the following:

f = list(artifact.files(names=['last.pt'], per_page=1000))
print(f[0].url)

You can have multiple filenames in there and access their attributes from the created list. The artifact.files is an iterator of File objects (which are the ones with the url method).

Regarding the issue with artifact._files this should be fixed if you upgrade to the most recent version according to this commit. Hope this helps!
