We recommend to run this package inside a dedicated anaconda/miniconda python environment. However, it has also been successfully tested on Ubuntu 14.04.

We assume that you have anacondan or miniconda installed on your system. You can download it from

Use the requirements file, lcp.yml (or lcp_OSX.yml if you are on Mac Os), distributed with the repository to create a new environment

conda-env create -f lcp.yml

This will in set up a anaconda/miniconda python environment LCP, which can be used by invoking

source activate LCP

Now install empca.py (see below)

Follow this procedure to get install all dependencies on a fresh Ubuntu 14.04:

• Add the universe repositories for scipy (if they are not already enabled):

sudo add-apt-repository universe
sudo apt-get update

• Install necessary packages:

sudo apt-get install python-dev
sudo apt-get install python-numpy python-scipy python-matplotlib

• On new Ubuntu systems you can install sklearn from the default repository:

sudo apt-get install python-sklearn

Finally, install empca.py (see below)

The lc_predictor module requires the empca.py (Bailey 2012). Download it and put it in a location where python will find it, e.g.: using wget

wget https://github.com/sbailey/empca/raw/master/empca.py \
    -O $HOME/.local/lib/python2.7/site-packages/empca.py

or curl

curl -L https://github.com/sbailey/empca/raw/master/empca.py -o \
    -o $HOME/.local/lib/python2.7/site-packages/empca.py

or by manually downloading and moving it.

If you are using anaconda/miniconda, you could also move it to the environment directory. In the case of miniconda (assuming a standard installation) this would be

$HOME/miniconda2/envs/LCP/lib/python2.7/site-packages/

• Go in the directory where you extracted the code:

cd lc_predictor/

• If your are using anaconda/miniconda, activate the environment

source activate LCP

• Install the package globally:

python setup.py install

• OR Install the package locally:

python setup.py install --user

• Test it!

cd lc_predictor/bin/
python fit_lc.py

If everything worked, a number of pdf files should have been created in the out_dir folder.
