Envoyé par: indie

Bonjour,

j'ai besoin d'installer slepc4py, (je dois installer aussi SLEPc) pour faire simple j'ai utilisé la commande "pip installe slepc slepc4py" sans succès:

J'ai testé "easy_install slepc4py" mais ca ne fonctionne pas non plus: 


 
root@user-UX331UN:/home/user/slepc-3.8.2# easy_install slepc4py
Searching for slepc4py

error: Setup script exited with error: command '/usr/bin/mpicc' failed with exit status 1


Je crois qu'il y a des problèmes de dépendance avec PETSc.
Avez vous une idée pour m'aider à avancer svp?

Merci

Re: installation SLEPc et slepc4py
Envoyé par: Jiel

Il me semble que pip n'arrive pas à trouver slepc. Peut-être que la solution est de réinstaller slepc ou de vérifier les permissions de slepc là où il est installé :
/usr/local/lib/python2.7/dist-packages/slepc-3.8.0-py2.7.egg

La gestion des bibliothèques python est fréquemment un casse-tête sous GNU/Linux. Tu peux essayer de nettoyer ce qui a été éventuellement mal installé :
pip uninstall slepc slepc4py
puis supprimer tout ce qui resterait : rm -rf /usr/local/lib/python2.7/dist-packages/slepc*
et de retenter une installation.

Souvent, lors d'un problème avec pip, installer le package officiel de la distribution à la place peut résoudre le problème.
Ainsi, supprimer avec pip la bibliothèque (au cas où il resterait des fichiers quelque part), puis installer le paquet de la distribution : ainsi sous Debian/Ubuntu apt-get install python-slepc4py
