SciPy / Python installé sur Ubuntu

Je suis actuellement en train de suivre le tutoriel Installation de SciPy Stack pour installer SciPy sur Ubuntu 12.04 (Precise Pangolin) (je ne peux pas utiliser apt-get install car j’ai besoin d’une version récente).

Cependant, je reçois des erreurs lorsque je fais les commandes suivantes:

De plus, comment tester si ce module a été installé correctement?

PyPM est un bon moyen de l’installer. La version bêta 0.10.1 inclut toutes les dépendances. Vous avez besoin d’ Active Python pour accéder à PyPM, mais vous devriez pouvoir l’installer facilement.

 pypm install scipi

Mon travail habituel consiste à utiliser une virtualenv pour avoir une dissortingbution Python avec des paquets à jour.

Dans cet environnement, vous pouvez installer et mettre à jour tous les paquets dont vous avez besoin avec pip et sans appels sudo .

Donc, si vous n’avez besoin que de SciPy (et NumPy ), ce serait:

 $ sudo apt-get install python-virtualenv python-pip $ sudo apt-get build-dep python-numpy python-scipy $ # Create virtualenv in home $ virtualenv .myenv $ # Activate the virtualenv $ source .myenv/bin/activate (myenv)$ pip install -U numpy (myenv)$ pip install -U scipy

(Si vous ne disposez pas d’un access root, vous pouvez installer virtualenv et pip comme décrit ici . Cependant, vous avez besoin des dépendances de NumPy et SciPy.)

Vous pouvez inclure la source .myenv/bin/activate dans votre .bash_profile et votre shell commencera toujours par cet environnement. Si vous utilisez des fichiers d’exigences, il est facile d’installer et de maintenir les mêmes environnements sur toutes vos machines.

Eu le même problème. Les suivants ont fonctionné pour moi:

 sudo apt-get install libblas-dev sudo apt-get install liblapack-dev sudo apt-get install gfortran

Vous devez télécharger et installer Atlas comme le suggère la sortie. Après cela, réessayez l’installation de SciPy.

Une autre option serait apt-get install ancienne version. Cela va installer automatiquement toutes les dépendances; puis installez le plus récent à la main. Cela se traduira par deux bibliothèques sur votre machine, l’une dans /usr/share/pyshared plus probable et une autre quelque part dans /usr/local , mais vous pouvez vous assurer qu’elle est chargée en modifiant le chemin de chargement du module.

De plus, si vous lancez --prefix=/usr/local , en installant une nouvelle version par-dessus une ancienne version, celle-ci sera simplement écrasée et la gestion des chemins ne sera pas requirejse.

 sudo apt-get install python-scipy

J’ai eu le même problème que l’OP (sur Red Hat Linux 5.7 pour moi; oui, je sais que c’est vieux) et tout a été corrigé en installant les en-têtes ATLAS (et “static libs”, cela dit) via:

  yum install atlas-devel

Pour Fedora 20:

 pip install virtualenv virtualenvwrapper mkvirtualenv scipy_project sudo yum-buildep scipy pip install scipy

J’espère que ça aide!
