I’ve compiled OpenMC from source on an offline Linux system but am now struggling to get the Python API to work. The guidance documentation [2. Installation and Configuration — OpenMC Documentation](https://docs.openmc.org/en/stable/usersguide/install.html#installing-python-api) assumes you’re working on a networked system. Is there any guidance on how to do this offline?

I’ve already obtained the required third-party Python packages.

@Chris welcome to the community! If you already have the required Python dependencies installed, you should be able to run:

```bash
pip install --no-deps --no-build-isolation .

```

The `--no-deps` flag ensures that pip doesn’t try to install run-time dependencies whereas `--no-build-isolation` ensures it doesn’t install build-time dependencies.
