# VGGT-Omega 1B 256 OXE/MimicGen/RoboCasa365 Step 62000

This repo contains the portable model checkpoint `0062000.pt` and the DeepSpeed ZeRO-2 checkpoint shards needed for optimizer-state resume.

Important: because this run used DeepSpeed ZeRO-2, `0062000.pt` intentionally stores `optimizer: null`. Optimizer state lives in `checkpoints/0062000/`.

To resume with optimizer/scheduler state in this codebase, keep the sibling layout:

```text
0062000.pt
checkpoints/0062000/
  bf16_zero_pp_rank_0_mp_rank_00_optim_states.pt
  ...
  bf16_zero_pp_rank_7_mp_rank_00_optim_states.pt
  mp_rank_00_model_states.pt
```

Then pass `--ckpt /path/to/0062000.pt` with the `checkpoints/0062000/` directory present; `train_robot.py` resolves the sibling ZeRO folder and calls DeepSpeed `load_checkpoint(tag="0062000")`.
