Bonjour à tous,
je suis un débutant avec les systèmes linux et je rencontre un problème. Je suis sous Debian 8, je sais que le forum est pour ubuntu, mais je n'ai pas encore de mot de passe pour poster sur le forum Debian.
A l'installation de Debian 8 (sur partition), Python 2.7 est déjà installé (cf dans le synaptic par exemple).
Je souhaite installer le module scipy pour Python (module numpy déjà installé par défaut).
1er échec (cf
http://www.scipy.org/install.html) :
root@PC-LATITUDE:~# apt-get install python-scipy
Lecture des listes de paquets... Fait
Construction de l'arbre des dépendances
Lecture des informations d'état... Fait
E: Impossible de trouver le paquet python-scipy
J'installe alors l'utilitaire pip de python pour télécharger scipy puis l'installer (cf
https://www.google.fr/url?sa=t&rct=j&q=&esrc=s&source=web&cd=2&ved=0CDEQFjAB&url=https%3A%2F%2Fbootstrap.pypa.io%2Fget-pip.py&ei=7iOdVb-rC4X0UJrPm7AL&usg=AFQjCNE8Fo9j_sgo1hBzEoUT39H85hFDrg).
installation de pip :
root@PC-LATITUDE:~# python "/home/bpiton/Téléchargements/get-pip.py"
Requirement already up-to-date: pip in /usr/local/lib/python2.7/dist-packages
Je tente d'installer scipy via pip (cf
https://pip.pypa.io/en/latest/user_guide.html). J'obtiens alors l'ensemble d'erreur suivante (que je reconnais ne pas comprendre dans son intégralité):
root@PC-LATITUDE:~# pip install scipy

De ce que je comprends, il faut alors que j'installe les librairies ATLAS, BLAS et LAPACK ou alors que je trouve le fichier wheel qui n'arrive pas à être construit.
Scipy a effectivement des dépendances d'installation (cf
https://packages.debian.org/jessie/python-scipy).
J'essaie alors d'installer en 1er lieu la librairie LAPACK (par exemple) :
root@PC-LATITUDE:~# apt-get install liblapack-dev
Lecture des listes de paquets... Fait
Construction de l'arbre des dépendances
Lecture des informations d'état... Fait
E: Impossible de trouver le paquet liblapack-dev
Mais en vain. J'ai essayé via aptitude, le synaptic (qui ne trouve pas "liblapack-dev"), et easy_install mais tous sont en échec pour installer une des librairies mentionnées au dessus.
Je suspecte donc qu'il y à un problème avec mon "apt-get" mais je ne trouve pas.
Quelqu'un saurait-il quoi faire ?
Merci,
Benjamin.
