Dataset download

To download nuScenes you need to go to the Download page, create an account and agree to the nuScenes Terms of Use. After logging in you will see multiple archives. For the devkit to work you will need to download all archives. Please unpack the archives to the /data/sets/nuscenes folder *without* overwriting folders that occur in multiple archives. Eventually you should have the following folder structure:

/data/sets/nuscenes
    samples	-	Sensor data for keyframes.
    sweeps	-	Sensor data for intermediate frames.
    maps	-	Folder for all map files: rasterized .png images and vectorized .json files.
    v1.0-*	-	JSON tables that include all the meta data and annotations. Each split (trainval, test, mini) is provided in a separate folder.

If you want to use another folder, specify the dataroot parameter of the NuScenes class (see tutorial).

CAN bus expansion

In February 2020 we published the CAN bus expansion. It contains low-level vehicle data about the vehicle route, IMU, pose, steering angle feedback, battery, brakes, gear position, signals, wheel speeds, throttle, torque, solar sensors, odometry and more. To install this expansion, please follow these steps:

  • Download the expansion from the Download page,
  • Move the can_bus folder to your nuScenes root directory (e.g. /data/sets/nuscenes/can_bus).
  • Get the latest version of the nuscenes-devkit.
  • If you already have a previous version of the devkit, update the pip requirements (see details): pip install -r setup/requirements.txt
  • Get started with the readme or tutorial.

Map expansion

In July 2019 we published a map expansion with 11 semantic layers (crosswalk, sidewalk, traffic lights, stop lines, lanes, etc.). To install this expansion, please follow these steps:

  • Download the expansion from the Download page,
  • Move the four .json files to your nuScenes maps folder (e.g. /data/sets/nuscenes/maps).
  • Get the latest version of the nuscenes-devkit.
  • If you already have a previous version of the devkit, update the pip requirements (see details): pip install -r setup/requirements.txt
  • Get started with the tutorial.

Devkit setup

The devkit is tested for Python 3.6 and Python 3.7. To install Python, please check here.

Our devkit is available and can be installed via pip :

pip install nuscenes-devkit

For an advanced installation, see installation for detailed instructions.
