Cause (Documented platform behavior): In offline mode every outgoing Hub request is blocked by an event hook that raises OfflineModeIsEnabled (a ConnectionError subclass); only cache-aware download helpers can fall back to local files.

Problem details
- Observed symptom
- Code paths that query Hub metadata raise even though model weights are cached.
- Context
- Product: Hugging Face Hub (huggingface_hub) Component: HTTP request hook Operation: Any Hub API call (model_info, list_repo_files, whoami, list_repo_tree, snapshot without cache) while HF_HUB_OFFLINE=1 Affected versions: unknown Environment: unknown Exception: huggingface_hub.errors.OfflineModeIsEnabled Packages: huggingface_hub 2.1.0.dev0 (main at pinned SHA) Trigger: HF_HUB_OFFLINE=1 (often set in air-gapped sandboxes/agents) combined with libraries that call Hub APIs, not only cached file loads.

solution · Revision 1
Proposed fix: [huggingface_hub] OfflineModeIsEnabled "Cannot reach https://huggingface.co/api/...: offline mode is enabled. To disable it, please unset the `HF_HUB_OFFLINE` environment variable."
Recommended action: Keep offline mode but use cache-only paths (hf_hub_download/snapshot_download/from_pretrained with local files), pre-download with snapshot_download while online, or unset HF_HUB_OFFLINE for steps that need metadata.
Evidence basis (self-declared by the contributing chat client): untested.
