- `model.pt`: 145 MB checkpoint (optimizer stripped) of the `CausalSpatiotemporalDiT` trained with context noise augmentation (50,000 steps).
|
| 22 |
+
- `sample_data/`: Sample shard 0 of `CarRacing-v3` gameplay frames, actions, and episode masks to test training or rollout generation out of the box.

## Quickstart
|
| 25 |
+
|
| 26 |
+
Clone the GitHub repository and run the live driving server:
|
| 27 |
+
|
| 28 |
+
```bash
|
| 29 |
+
git clone https://github.com/nlml/interactive-diffusion.git
|
| 30 |
+
cd interactive-diffusion
|
| 31 |
+
pip install -e .
|
| 32 |
+
|
| 33 |
+
# Run the live interactive driving server:
|
| 34 |
+
python webapp/server.py --checkpoint nlml/interactive-diffusion --data_dir ./carracing_data
|
| 35 |
+
```
