The generation of environments facilitate the specific requiremnts of each user for each purpose.

Following instructions from python environments

1. Creation of the place where the environment will reside

$ mkdir -p ${HOME}/bin/py27env
$ cd ${HOME}/bin/py27env

1. Install virtualenv

$ pip install virtualenv

1. Test installation

$ virtualenv --version

1. Create a virtual environment (e.g `py27env' to be used with python 2.7):

$ virtualenv -p /usr/bin/python2.7 ./

1. Activate the environment

$ source ${HOME}/bin/py27env/bin/activate
(py27env) $

1. Installing packages

(py27env) $ pip install numpy
Collecting numpy
  Using cached numpy-1.13.3-cp27-cp27mu-manylinux1_x86_64.whl
Installing collected packages: numpy
Successfully installed numpy-1.13.3

1. To know which packages are installed

(py27env) $ pip freeze
numpy==1.13.3

1. Deactivating environment

(py27env) $ deactivate
$ 

Matplotlib

There are certain installation problems referred to the `mpl_toolkit'

1. On a given instaltion:

(py27env) $ pip freeze
backports.functools-lru-cache==1.4
cycler==0.10.0
ecmwf-api-client==1.5.0
matplotlib==2.1.0
netCDF4==1.3.1
numpy==1.13.3
pyparsing==2.2.0
python-dateutil==2.6.1
pytz==2017.3
scipy==1.0.0
six==1.11.0
subprocess32==3.2.7

• There is not `basemap'

from mpl_toolkits.basemap import Basemap
ImportError: No module named basemap

• but it is not found in the pip

(py27env) $ pip install basemap
Collecting basemap
  Could not find a version that satisfies the requirement basemap (from versions: )
No matching distribution found for basemap

• Thus, we will need to manually install `matplotlib' and `basemap' (following Matplolib installation. Unpacking the different packages...

(py27env) $ mkdir $HOME/Downloads
(py27env) $ cd Downloads/
