Multiple Futures Prediction on CARLA data

This repository accompanies the paper Contingencies From Observations (CfO) (ICRA 2021) and implements the Multiple Futures Prediction (MFP) baseline in the paper. It is based on the public repository https://github.com/apple/ml-multiple-futures-prediction from the authors of the MFP paper.

The MFP architecture has been modified from the original repo to not use attention (the scenarios used in the CfO paper only use 2 agents). Additionally, it has been modified to support rotation of model inputs based on the each vehicle's yaw, such that the reference frame (for prediction) always starts with the ego vehicle at (0,0) and pointing in the +X direction. See the CfO paper appendix for further details.

MFP models trained on the CfO dataset can be used for planning, e.g., to control a vehicle in the CARLA simulator. To use an MFP model for control in a CfO scenario, follow the instructions for running MFP models in the CfO repository.

Installation

The install follows the original MFP repo with some small modifications:

python3.6 -m venv .venv # Create new venv
source ./venv/bin/activate # Activate it
conda install pytorch==1.1.0 torchvision==0.3.0 cudatoolkit=10.0 -c pytorch
pip install -U pip # Update to latest version of pip
pip install -r requirements.txt # Install everything

CARLA Dataset

This repo trains an MFP model on the same dataset used in CfO.

First download (or generate) the CfO dataset following the instructions in the CfO repo.

Next, either copy the dataset to the multiple_futures_prediction folder, or create a link pointing to the dataset folder:

cd multiple_futures_prediction
ln -s your/copy/of/cfo/dataset ./carla_dataset_cfo

This should create the following directory structure:

multiple_futures_prediction/carla_data_cfo/Left_Turn_Dataset
multiple_futures_prediction/carla_data_cfo/Right_Turn_Dataset
multiple_futures_prediction/carla_data_cfo/Overtake_Dataset

Usage

To train a model, run train_carla_cmd on a desired config file:

python -m multiple_futures_prediction.cmd.train_carla_cmd \
--config multiple_futures_prediction/configs/mfp_carla_rightturn.py

To visualize a model checkpoint, run demo_carla_cmd to replay files from training with predictions overlaid with ground truth at each timestep:

python -m multiple_futures_prediction.cmd.demo_carla_cmd \
--checkpoint-dir CARLA_right_turn_scenario \  # directory with the saved model checkpoint
--outdir mfp_carla_rightturn \  # directory to write the images and video to
--frames 200  # how many frames to include in the video

This repo includes saved models for each scenario in the paper, located in checkpts (their corresponding config files can be found in the configs folder):

python -m multiple_futures_prediction.cmd.demo_carla_cmd --checkpoint-dir CARLA_left_turn_scenario --outdir mfp_carla_leftturn --frames 200
python -m multiple_futures_prediction.cmd.demo_carla_cmd --checkpoint-dir CARLA_right_turn_scenario --outdir mfp_carla_rightturn --frames 200
python -m multiple_futures_prediction.cmd.demo_carla_cmd --checkpoint-dir CARLA_overtake_scenario --outdir mfp_carla_overtake --frames 200
