Installing#

pip install pspy [--user]

You can test your installation by running

test-pspy

If everything goes fine, no errors will occur. Otherwise, you can report your problem on the Issues tracker.

If you plan to develop pspy, it is better to checkout the latest version by doing

git clone https://github.com/simonsobs/pspy.git /where/to/clone

Once downloaded, you can install using pip install . inside the project directory. We use the meson build system, which should be understood by pip (it will build in an isolated environment).

To run an editable install, you will need to do so in a way that does not have build isolation (as the backend build system, meson and ninja, actually perform micro-builds on usage in this case).

Then you can install the pspy library and its dependencies via

pip install --upgrade pip setuptools meson ninja meson-python numpy
pip install --no-build-isolation --editable /where/to/clone

The -e option allow the developer to make changes within the pspy directory without having to reinstall at every changes.
