Datasets

VectorWorld currently supports:

• Waymo Open Motion Dataset v1.1.0
• nuPlan

Raw-data conversion

Before VectorWorld preprocessing, the raw datasets should first be converted into extracted scenario files. We follow the Scenario Dreamer-style preprocessing pipeline:

• Waymo conversion script: generate_waymo_dataset.py
• nuPlan conversion script: generate_nuplan_dataset.py

In this repository, the corresponding extraction entry points are:

• scripts/extract_waymo_data.sh
• scripts/extract_nuplan_data.sh

Repository preprocessing scripts

The main preprocessing scripts are:

• scripts/preprocess_waymo.sh
• scripts/preprocess_nuplan.sh
• scripts/preprocess_deltasim_waymo.sh
