Building

Requirements

Only strict requirements are:

  • numpy

  • scipy

  • pyyaml

  • mpi4py

  • cosmoprimo (currently with pyclass to compute DESI fiducial cosmology)

Should be made optional in the future:

  • mpi4py

  • pyclass (by extending TabulatedDESI to power spectra)

Extra requirements are:

  • plotting: tabulate for nice tables; getdist, anesthetic to make nice contour plots

  • jax: for automatic differentiation

pip

To install desilike, simply run:

python -m pip install git+https://github.com/cosmodesi/desilike

If you want to install extra requirements, run:

python -m pip install git+https://github.com/cosmodesi/desilike#egg=desilike[plotting,jax]

git

First:

git clone https://github.com/cosmodesi/desilike.git

To install the code:

pip install --user

Or in development mode (any change to Python code will take place immediately):

pip install --user -e .

You may want to avoid installing dependencies in your local $HOME (in particular if you load the cosmodesi environment):

pip install --no-deps --user -e .

Pipeline dependencies, samplers, profilers, emulators

Requirements for samplers, profilers, emulators can be installed within Python, with the provided installer.

Any calculator, profiler, sampler, etc. can be installed with Installer.
