Image not found

Error message

Image not found

What it means

Raised by GET /eval-sets/{set_name}/images/{filename} (404) when the set and inputs/ directory exist and the filename passed the .png check, but no file with that name is on disk (resolve_set_image_path raises FileNotFoundError at sets.py:302). It is the plain missing-file case.

Solutions

1. List the set's actual images via GET /eval-sets/{set_name} and use an exact filename.
2. Check case: the extension check is case-insensitive but the filesystem lookup is exact.
3. Restore or re-add the missing image to inputs/ if a manifest still references it.

Example fix

# before
GET /eval-sets/my-set/images/hero01.png  # 404 'Image not found'

# after
detail = requests.get(url + "/eval-sets/my-set").json()
fname = detail["images"][0]["filename"]
GET /eval-sets/my-set/images/{fname}

detail = requests.get(url + f"/eval-sets/{set_name}").json()
known = {i["filename"] for i in detail.get("images", [])}
if filename not in known:
    raise LookupError(f"{filename!r} not among {sorted(known)}")

def image_in_set(filename: str, detail: dict) -> bool:
    return any(i.get("filename") == filename for i in detail.get("images", []))

resp = requests.get(url + f"/eval-sets/{set_name}/images/{filename}")
if resp.status_code == 404 and "Image not found" in resp.text:
    filename = next(i["filename"] for i in requests.get(url + f"/eval-sets/{set_name}").json()["images"])
    resp = requests.get(url + f"/eval-sets/{set_name}/images/{filename}")
resp.raise_for_status()

When it happens

Trigger: Requesting 'missing.png' for a set whose inputs directory lacks that file — typo, wrong set, or a file listed in a stale manifest that was deleted from disk.

Common situations: Manifest/filenames out of sync with disk after manual deletion; case-sensitivity mismatch (Shot.PNG vs shot.png on Linux); copying URLs between sets.
