# Dataset configuration

#### Specifying dataset

The dataset path and type is specified in the model config. Both `dataset_inputs_train` and a `dataset_inputs_eval` need to be set. You can see `configs/graph_default.yaml` for more details on what a full config would look like.

```yaml
data:
  dataset_inputs_train:
    data_directory: data/instant_ngp/fox
    dataset_format: instant_ngp
    downscale_factor: 1
    alpha_color: white
  dataset_inputs_eval:
    data_directory: data/instant_ngp/fox
    dataset_format: instant_ngp
    downscale_factor: 1
    alpha_color: white
```

#### Visualize dataset

You can use `notebooks/visualize_dataset.ipynb` to see how your formatted dataset looks. This code will load a dataset from a yaml config, show the camera poses, and visualize rays with the specified collider in the config. TODO: add a better visualization with images too
