Installing PTA software

1. Install Miniconda

   • Either...download and install the relevant Miniconda file from here: https://docs.conda.io/en/latest/miniconda.html
   • OR... use Terminal command line installation

     • Download the right one for your architecture

       • Mac: wget -q https://repo.anaconda.com/miniconda/Miniconda3-latest-MacOSX-x86_64.sh
       • Linux: wget -q https://repo.continuum.io/miniconda/Miniconda3-latest-Linux-x86_64.sh
       • Windows (untested): wget -q https://repo.anaconda.com/miniconda/Miniconda3-latest-Windows-x86_64.exe

     • bash Miniconda3-latest-Linux-x86_64.sh -b

     • rm Miniconda3-latest-Linux-x86_64.sh (careful with “rm”)

2. Create a conda environment. Environments are a simple way to create an enclosed sandbox for all of the software for a given project. It will not pollute any other version of python or others versions of your software, provided you stay in the environment.

   • See https://docs.conda.io/projects/conda/en/latest/user-guide/tasks/manage-environments.html.
   • Simple environment: conda create -n test_env python=3.7 numpy scipy matplotlib Cython basemap pandas astropy jupyter notebook mpi4py h5py
   • To enter the environment: conda activate test_env
   • Once inside, to install other packages: conda install <package_name>
   • To exit the environment: conda deactivate
   • To delete the environment: conda remove --name test_env --all

3. To install a new environment from a yaml file: conda env create --file environment.yaml
