MPPI Playground

This repository contains an implementation of Model Predictive Path Integral Control (MPPI) with PyTorch to accelerate computations on the GPU.

Tested Native Environment

Ubuntu Focal 20.04 (LTS)
NVIDIA Driver 510 or later due to PyTorch 2.x

Dependencies

cuda 11.8
Python 3.10
PyTorch 2.0

Docker Setup

Install Docker

Installation guide

# Install from get.docker.com
curl -fsSL https://get.docker.com -o get-docker.sh
sudo sh get-docker.sh
sudo groupadd docker
sudo usermod -aG docker $USER

Setup GPU for Docker

Installation guide

curl -fsSL https://nvidia.github.io/libnvidia-container/gpgkey | sudo gpg --dearmor -o /usr/share/keyrings/nvidia-container-toolkit-keyring.gpg \
  && curl -s -L https://nvidia.github.io/libnvidia-container/stable/deb/nvidia-container-toolkit.list | \
    sed 's#deb https://#deb [signed-by=/usr/share/keyrings/nvidia-container-toolkit-keyring.gpg] https://#g' | \
    sudo tee /etc/apt/sources.list.d/nvidia-container-toolkit.list 

sudo apt-get update

sudo apt-get install -y nvidia-container-toolkit nvidia-container-runtime

sudo nvidia-ctk runtime configure --runtime=docker

sudo systemctl restart docker

Installation

with Docker (Recommend)

# build container
make build

# Open remote container via Vscode (Recommend)
# 1. Open the folder using vscode
# 2. Ctrl+P and select 'devcontainer rebuild and reopen in container'
# Then, you can skip the following commands

# Or Run container via terminal
make bash

with venv

python3 -m venv .venv
source .venv/bin/activate
pip3 install -e .[dev]
