Installation

$ conda install -c conda-forge redback

Supported python versions: 3.7+.

This will install all requirements for running redback for general transient fitting, including bilby and our default sampler dynesty. Other samplers will need to be installed via pip or the appropriate means. Please look through redback fitting documentation for what samplers are available. Currently redback is going significant development, and we can not guarantee that any pip or conda releases will be completely up to date. Therefore, for the near future, we recommend installing redback from source, and in development mode.

Install redback from source

redback is developed and tested with Python 3.7+. In the following, we assume you have a working python installation, python pip, and git.

Clone the repository, install the requirements, and then install the software:

$ git clone https://github.com/nikhil-sarin/redback
$ cd redback/
$ pip install -r requirements.txt
$ pip install .

To install with development mode, use:

$ git clone https://github.com/nikhil-sarin/redback
$ cd redback/
$ pip install -r requirements.txt
$ pip install -e .

For full functionality, please also install optional requirements.

$ pip install -r optional_requirements.txt

You are now ready to use redback. Please check out the examples

Install phantomjs

If you want to use redback functionality to download Swift data you need to install phantomjs. Installing phantomjs essentially requires that you first download the phantomjs file for your operating system from the website. Then create a softlink or export the path to the bin file; see discussion on stackoverflow.

If you use homebrew on Mac then you don’t need to follow the above steps and can simply do

$ brew install --cask phantomjs

Or use pkg installer if you are on linux.

$ sudo pkg install phantomjs
