# SimpleVLA GRPO Runtime Fallback

This dataset contains the optional captured `venv_isaaclab` runtime fallback.
It is provided for machines close to the original Ubuntu/CUDA setup.

Isaac Sim is not included. Install the matching official Isaac Sim 5.1.0
release separately and set `ISAACSIM_PATH=/path/to/isaac-sim`.

The runtime archive is published as split files:

```text
venv_isaaclab_ubuntu22_cuda124_py311.tar.zst.part-000
venv_isaaclab_ubuntu22_cuda124_py311.tar.zst.part-001
...
```

The installer concatenates these parts automatically.

Recommended installation from the code repository:

```bash
bash scripts/download_runtime_fallback.sh
export ISAACSIM_PATH=/path/to/isaac-sim
bash scripts/install_venv_fallback.sh
source activate_simplevla_runtime.sh
bash scripts/verify_runtime.sh
```
