Data Preparation

1. Download nuScenes

Download the nuScenes dataset to ./data/nuscenes.

2. Download annotations

Download the annotation files to ./data/nuscenes/annotations.

3. Download pretrained weights

Using pre-trained weights from the external dataset i.e.nuImages needs to download to ./checkpoints .

Folder structure

After preparation, you will be able to see the following directory structure:
