To get started with NAVSIM:
Clone the repository
git clone https://github.com/autonomousvision/navsim.git
cd navsim
You need to download the OpenScene logs and sensor blobs, as well as the nuPlan maps. We provide scripts to download the nuplan maps, the mini split and the test split. Navigate to the download directory and download the maps
NOTE: Please check the LICENSE file before downloading the data.
cd download && ./download_maps
Next download the data splits you want to use. Note that the dataset splits do not exactly map to the recommended standardized training / test splits- Please refer to splits for an overview on the standardized training and test splits including their size and check which dataset splits you need to download in order to be able to run them.
You can download the mini, trainval, test and private_test_e2e dataset split with the following scripts
./download_mini
./download_trainval
./download_test
./download_private_test_e2e
Also, the script ./download_navtrain
can be used to download a small portion of the trainval
dataset split which is needed for the navtrain
training split.
This will download the splits into the download directory. From there, move it to create the following structure.
~/navsim_workspace
├── navsim (containing the devkit)
├── exp
└── dataset
├── maps
├── navsim_logs
| ├── test
| ├── trainval
| ├── private_test_e2e
│ └── mini
└── sensor_blobs
├── test
├── trainval
├── private_test_e2e
└── mini
Set the required environment variables, by adding the following to your ~/.bashrc
file
Based on the structure above, the environment variables need to be defined as:
export NUPLAN_MAP_VERSION="nuplan-maps-v1.0"
export NUPLAN_MAPS_ROOT="$HOME/navsim_workspace/dataset/maps"
export NAVSIM_EXP_ROOT="$HOME/navsim_workspace/exp"
export NAVSIM_DEVKIT_ROOT="$HOME/navsim_workspace/navsim"
export OPENSCENE_DATA_ROOT="$HOME/navsim_workspace/dataset"
Finally, install navsim. To this end, create a new environment and install the required dependencies:
conda env create --name navsim -f environment.yml
conda activate navsim
pip install -e .
