Install

In case you want to install (in any other machine!)

1. Getting to the downloads folder

$ mkdir Downloads
$ cd Downloads

1. Getting the installer for python 2.7

wget https://repo.continuum.io/archive/Anaconda2-4.4.0-Linux-x86_64.sh

1. Execution of the installer

$ bash Anaconda2-4.4.0-Linux-x86_64.sh
(...)
install path: /home/lluis.fita/bin/anaconda2
(...)
Do you wish the installer to prepend the Anaconda2 install location
to PATH in your /home/lluis.fita/.bashrc ? [yes|no]
>>> no
You may wish to edit your .bashrc or prepend the Anaconda2 install location:
$ export PATH=/home/lluis.fita/bin/anaconda2/bin:$PATH

cration of an environtment

A python environtment is useful to have set-up an specific set of packages to be used for python. Folowing instructions from conda EnvironmentCreation

1. Creation of the environemnt called ‘lluis’ with ptyhon 2.7 version of codes

conda create --name lluis python=2.7

1. To activate the environment

$ source (...)/anaconda2/bin/activate lluis
(lluis) $

1. Knowing packages of the environtment:

$ conda list -n lluis
# packages in environment at /home/lluis.fita/datosskogul/minconda3/envs/lluis:
#
ca-certificates           2017.7.27.1                   0    conda-forge

$ pip install numpy

1. Deactivate environtment:

(lluis) $ source deactivate
$
