Python environment setup guide
===============================

**1. Installing Anaconda2**

1) Download Anaconda2

.. code-block:: bash

  $ wget https://repo.anaconda.com/archive/Anaconda2-5.1.0-Linux-x86_64.sh

2) Run the installer (Installer requires bzip, please install it if you don't have it)

.. code-block:: bash

  $ bash ./Anaconda2-5.1.0-Linux-x86_64.sh

More information about Anaconda can be found from `Anaconda Documentation`_.

.. _Anaconda Documentation: https://docs.anaconda.com/anaconda/

3) Add Anaconda2 to PATH

.. code-block:: bash

  $ export PATH=/home/<user>/anaconda2/bin:$PATH
  $ . /home/<user>/anaconda2/etc/profile.d/conda.sh


**2. Setting up gemx environment to include all conda packages used by GEMX Python APIs.**

.. code-block:: bash

  $ conda config --add channels anaconda
  $ conda create --name gemx python=2.7.14 numpy=1.14.5 scipy=1.2.1 -c defaults
  $ conda activate gemx
  $ conda install pandas=0.24.1
  $ conda install keras=2.2.4
  $ conda install scikit-learn=0.20.2

Note: above three installation steps are only needed when you first activate the gemx environment. 

**3. Deactivate gemx environment after testing**

Note: Please don't take this step if you intend to test/use GEMX Python APIs. 
You only take it after you've finished all testing.

.. code-block:: bash

  $ conda deactivate
