[editar] 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 ~/bin/anaconda2/bin/activate lluis
(lluis) $
  1. Knowing packages of the environtment: 
$ conda list -n lluis
