1. Install DockerCE on your machine by following the instruction

   • https://docs.docker.com/install/

2. Clone this repository

git clone https://github.com/mshr-h/onnx-dockerfile-for-raspberry-pi
cd onnx-dockerfile-for-raspberry-pi

3. Move to a folder where you want to build for and run docker build

cd 3.7-bullseye-build # Debian bullseye with Python 3.7
docker build -t onnx-arm32v7 -f Dockerfile.arm32v7 .
