inspect_job's status.stage is an enum (with .value) in some
huggingface_hub versions and a plain str in others. The poller
assumed the enum shape, raising "'str' object has no attribute
'value'" on resume for users on the str-returning version.
Read it via getattr(..., "value", ...) so both shapes work, and
parametrize the poll test over enum and str stages so the str case
is actually exercised (the old mock only ever simulated the enum).
Address the latest Claude review on #3856:
- _build_resume_job no longer forwards --dataset.root to the pod (a
host-local path it can't read); the fresh-run path already nulls it in
build_remote_config_file, so this makes resume consistent. Add a unit
test for _pod_forwarded_args covering the drop in both flag forms.
- Restore the display-independent keyboard-control docs (n/r/q letter
equivalents + X11/Wayland/headless Tip) in il_robots.mdx that this
branch was stale on relative to main (#3875).
Addresses Caroline's review comment on PR #3856: the local import of
ensure_dataset_available inside submit_to_hf was vestigial. dataset.py
does not import hf.py, so there is no circular-import risk and no extra
load cost (its heavy deps stay lazy), so make it a top-level import.
Resolve the claude[bot] review on #3856:
- Reject reward-model training under --job.target with a clear error instead
of crashing on a None policy inside build_remote_config_file.
- Support --policy.path remote runs: validate() no longer requires repo_id for
remote runs (it is auto-generated in submit_to_hf), and repo_id/push_to_hub
are now set after validate() resolves the policy.
- Narrow the bare `except Exception` in _tail_logs/_poll_until_done to
(OSError, httpx.HTTPError) so programming errors surface instead of being
silently retried or counted as job failures.
- Install the SIGINT detach handler only on the main thread.
- Generate model repo timestamps in UTC.
huggingface_hub is a core dependency, so the per-function dynamic imports
had no lazy-loading rationale. Move them to a single module-level import
and update test monkeypatch targets to lerobot.jobs.hf.* accordingly.
When --job.target names a GPU flavor, train() dispatches to lerobot.jobs.submit_to_hf
instead of training locally: it authenticates, ensures the dataset is on the Hub
(pushing a local-only one privately), serializes a pod-compatible train_config.json
(strips client-only fields, points at the model repo), submits via HfApi.run_job
with HF_TOKEN/WANDB_API_KEY secrets, then streams logs and finishes when the model
is pushed. Wires push_checkpoint_to_hub into the training loop behind
save_checkpoint_to_hub, and tags jobs/datasets/model with 'lerobot' + --job.tags.
