WIMP - What If Motion Predictor

Reference PyTorch Implementation for What If Motion Prediction [PDF] [Dynamic Visualizations]

Setup

Requirements

The WIMP reference implementation and setup procedure has been tested to work with Ubuntu 16.04+ and has the following requirements:

python >= 3.7
pytorch >= 1.5.0

Installing Dependencies

Install remaining required Python dependencies using pip.
```
pip install -r requirements.txt
```
Install the Argoverse API module into the local Python environment by following steps 1, 2, and 4 in the README.

Argoverse Data

In order to set up the Argoverse dataset for training and evaluation, follow the steps below:

Download the the Argoverse Motion Forecasting v1.1 dataset and extract the compressed data subsets such that the raw CSV files are stored in the following directory structure:

├── WIMP
│   ├── src
│   ├── scripts
│   ├── data
│   │   ├── argoverse_raw
│   │   │   ├── train
│   │   │   │   ├── *.csv
│   │   │   ├── val
│   │   │   │   ├── *.csv
│   │   │   ├── test
│   │   │   │   ├── *.csv

Pre-process the raw Argoverse data into a WIMP-compatible format by running the following script. It should be noted that the Argoverse dataset is quite large and this script may take a few hours to run on a multi-threaded machine.

python scripts/run_preprocess.py --dataroot ./data/argoverse_raw/ \
--mode val --save-dir ./data/argoverse_processed --social-features \
--map-features --xy-features --normalize --extra-map-features \
--compute-all --generate-candidate-centerlines 6

Usage

For a detailed description of all possible configuration arguments, please run scripts with the -h flag.

Training

To train WIMP from scratch using a configuration similar to that reported in the paper, run a variant of the following command:

python src/main.py --mode train --dataroot ./data/argoverse_processed --IFC \
--lr 0.0001 --weight-decay 0.0 --non-linearity relu  --use-centerline-features \
--segment-CL-Encoder-Prob --num-mixtures 6 --output-conv --output-prediction \
--gradient-clipping --hidden-key-generator --k-value-threshold 10 \
--scheduler-step-size 60 90 120 150 180  --distributed-backend ddp \
--experiment-name example --gpus 4 --batch-size 25

Questions

This repo is maintained by William Qi and Siddhesh Khandelwal - please feel free to reach out or open an issue if you have additional questions/concerns.

We plan to clean up the codebase and add some additional utilities (possibly NuScenes data loaders and inference/visualization tools) in the near future, but don't expect to make significant breaking changes.
