Comment installer scipy avec pip3?

Question

J'essaie d'installer scipy pour python3.x et j'essaie de l'installer avec pip3

Sudo pip3 install scipy

Mais j'ai les erreurs suivantes:

Comment installer scipy avec pip3? S'il n'y a pas de solution avec pip3, comment puis-je installer scipy pour python3.x?

Answer 1

Cela vous dit exactement ce que vous devez faire: installez toutes ces dépendances de construction.

Avant d’arriver, j’ai déjà dit à quelques reprises que je ne conseillais généralement pas aux utilisateurs pip (ou pip3) d’installer des packages dans leur installation globale Python. pip et apt-get sont complètement inconscients l'un de l'autre. Les fichiers peuvent être écrasés ou supprimés indûment et parce qu'une grande partie de votre système d'exploitation dépend de votre environnement Python, qu'il n'est pas recommandé de le manipuler.

Je recommanderais donc soit d’utiliser virtualenv (où tout est séparé du système), soit d’utiliser uniquement des packages déployés par le référentiel.

Cela dit, la raison technique pour laquelle vous ne pouvez pas installer est parce que SciPy a besoin de compiler une quantité de choses et qu'il a des dépendances externes pour beaucoup de cela. Celles-ci doivent être remplies. Vous pouvez le faire manuellement (en lisant l'erreur) ou, dans le cas où il existe une version du référentiel, vous pouvez demander à Apt d'installer les dépendances de construction:

Sudo apt-get build-dep python3-scipy

Et cela installera un nombre métrique de paquets. Notez que certaines de ces choses seront probablement des choses que vous avez déjà vues avec pip. Je vois beaucoup de choses numpy. Il faut se méfier.

Et vous auriez toujours besoin de suivre un processus similaire si vous construisez un virtualenv mais je déconseille d'utiliser apt pour répondre à vos dépendances car vous aurez probablement des versions différentes de ces dépendances. Ce n'est pas une recette de construction saine.

En bref, l'utilisation de la version repo est la plus simple.
