Building

Requirements

Only strict requirement is:

• numpy

Extra requirements are:

• pyfftw (for faster FFTs)

• fitsio, h5py, astropy to run pyrecon as a standalone

• pypower to evaluate reconstruction metrics (correlation, transfer function and propagator)

pip

To install pyrecon, simply run:

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

To run pyrecon as a standalone, a couple of extra dependencies are required (fitsio, h5py, astropy, scipy), which can be installed through:

python -m pip install git+https://github.com/cosmodesi/pyrecon#egg=pyrecon[extras]

git

First:

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

To install the code:

python setup.py install --user

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

python setup.py develop --user

pyrecon with Mac OS

If you wish to use clang compiler (instead of gcc), you may encounter an error related to -fopenmp flag. In this case, you can try to export:

export CC=clang

Before installing pyrecon. This will set clang OpenMP flags for compilation. Note that with Mac OS “gcc” may sometimes point to clang.
