| # ckpt_backup | |
| Backup of `robopolicy` training checkpoints and evaluation rollouts. | |
| ## Layout | |
| - `checkpoints/<run>/ckpt_final.pt` — 194 checkpoints. | |
| Optimizer state has been stripped: keys are `model_state_dict`, `processor_stats`, | |
| `run_config`, `scheduler_state_dict`, `step`. Inference/eval only — these cannot | |
| be resumed for further training. | |
| - `rollouts/<run>/<name>_rollouts/videos.tar` — per-run rollout videos (store-only tar). | |
| - `rollouts/<run>/<name>_rollouts/results.json|txt` — eval metrics, uncompressed. | |
| - `checkpoint_aliases.json` — 192 alias paths that were local symlinks | |
| to `ckpt_final.pt` (same step, identical weights). Recreate with | |
| `ln -s ckpt_final.pt <alias>` rather than downloading twice. | |
