Requirements

ophac requires Python 3.6+ and the following libraries:

• numpy
• scipy

Installation

From PyPI (recommended)

Precompiled wheels are available for common platforms. Just run:

pip install ophac

Local Installation (for development)

Use a virtual environment to avoid polluting your system Python:

python -m venv venv
source venv/bin/activate
pip install -e .

Building from Source (for unsupported platforms)

If you're on a platform without a prebuilt wheel (e.g., unusual Linux distro or Python version), pip will try to build ophac from source.

To build successfully, you must have:

• A C++17-compatible compiler (e.g., GCC ≥ 7, Clang ≥ 5, or MSVC ≥ 2017)
• Python development headers (e.g., python3-dev or equivalent)
• Build tools like make, cmake (if needed)

Make sure pip, setuptools, and wheel are up to date:

pip install --upgrade pip setuptools wheel

Then install:

pip install ophac

If building fails, you can clone the repository and install locally with:

git clone https://github.com/danielbakkelund/ophac.git
cd ophac
pip install .
