# Open Source Data for AMD AI DevMaster Hackathon 202608

## Upload to HuggingFace Hub

Upload the whole directory as a single dataset repo (replace `YOUR_HF_USERNAME` with your username):

```
export HF_TOKEN=hf_xxxxx 
hf upload WuChao-Cauchy/openSource_AMD_AI_DevMaster_Hackathon_202608 \
    /home/chao01.wu/BiGym_Dev/data/openSource_AMD_AI_DevMaster_Hackathon_202608 --repo-type=dataset
```

Create the dataset repo on the Hub first, or pass `--create-pr` to auto-create it.

## Download from HuggingFace Hub

`--local-dir` copies real files to disk (no symlinks) and resumes by default — if interrupted, re-running the same command continues where it left off, without restarting from scratch.

Full download:
```
hf WuChao-Cauchy
/openSource_AMD_AI_DevMaster_Hackathon_202608 \
    --repo-type=dataset --local-dir ./bigym_plus --max-workers 8
```

Download only specific tasks (glob matches directory names):
```
huggingface-cli download WuChao-Cauchy
/openSource_AMD_AI_DevMaster_Hackathon_202608 \
    --repo-type=dataset --local-dir ./bigym_plus \
    --include "reach_target/*" "reach_target_dual/*"
```

Common options:

- `--max-workers N`: concurrent download threads, default 8, can be raised on a good network.
- `--include "glob1" "glob2"`: download only matching files (e.g. `"<task>/*"` for a single task).
- `--exclude "glob1"`: skip matching files.
- `--force-download`: re-download even if files already exist locally.
- `--revision <commit>`: pin a specific commit / branch / tag.
- `--quiet`: disable progress bars, print only the final path.
- `--cache-dir PATH`: custom HF cache dir (default `~/.cache/huggingface`).

After download, each task subdirectory is a complete lerobot v3.0 dataset, loadable via `LeRobotDataset(repo_id="bigym_plus/<task>", root="./bigym_plus")`.
