* Séquence 2: Créer son propre environnement, automatiser sa construction et le partage
** 2.1 Récupérer une image de base
Nous allons créer un environnement "minimal" en terme de dépendances
et permettant d'exécuter le [[https://gitlab.inria.fr/learninglab/mooc-rr/mooc-rr-modele/blob/master/module2/exo5/exo5_fr.ipynb][notebook Jupyter de Challenger]].
L'idée pour bien contrôler son environnement va être de partir d'un
environnement minimaliste, dans lequel notre notebook aura d'ailleurs
peu de chances de s'exécuter, et d'y installer juste les logiciels
dont nous aurons besoin. Je partirai d'une image debian stable.
