Prerender

First we need to prepare data for training. The prerender script will convert the original data format into set of .npz files each containing the data for one scene. From code folder run

python3 prerender/prerender.py \
    --data_path /path/to/original/data \
    --output_path /output/path/to/prerendered/data \
    --config NCloseSegAndValidAgentRenderer

The prerender module is completely self-contained.

Encoder

Train

python3 train.py \
    --train_data_path /path/to/train/data \
    --val_data_path /path/to/validation/data \
    --config configs/Multipathpp32.yaml
    --save_folder /save/path

Rollout

python3 rollout.py \
    --test_data_path /path/to/test/data \
    --model_path /path/to/model \
    --config configs/Multipathpp32.yaml \
    --save_path /path/to/save/output
