Because of the challenging installation of the required python package pythonOCC-core is highly recommended to use a docker image.
The Docker repository source is available here and can be built locally:
git clone https://github.com/ReconCycle/urdf-from-step-docker.git
docker build -t urdf-from-step .
Build docker image is available here, and can be directly pulled like this:
docker pull ghcr.io/reconcycle/urdf-from-step:latest
