AstroVIPER

AstroVIPER (Visibility and Image Parallel Execution Reduction) is in development.

Installation

Linux

Create a virtual environment using any tool of your choice (venv, uv, mamba, conda etc.) and run

pip install astroviper

Mac

On macOS, pip install python-casacore does not work. Install it via conda-forge first (this requires an active conda/mamba environment)

conda install -c conda-forge python-casacore

Then install astroviper:

pip install astroviper

Developer Setup

git clone git@github.com:casangi/astroviper.git
cd astroviper
pip install -e '.[all]'     # builds the C++ extensions; '[all]' adds test/docs/interactive deps
pre-commit install          # installs ruff + nbstripout git hooks

• macOS: install casacore via conda first, because pip install python-casacore does not work on macOS:

  conda install -c conda-forge python-casacore

  This is only needed if you will be converting MSv2s to MSv4s or opening CASA images.
• After editing any .cpp / .hpp / CMakeLists.txt you must rebuild for the change to take effect (the C++ is compiled at install time):

  pip install -e '.[all]'   # or: pip install .

  scikit-build-core caches in build/{wheel_tag}/; if a build behaves oddly, delete build/ and reinstall. The -e creates an editable Python installation.
