Comment installer NumPy pour Python 3.6

Question

J'utilise Python 3.6b3 pour un projet de longue haleine, développé sous Windows . Pour ce projet, j'ai également besoin de NumPy . the beta . Quel est le meilleur moyen d'installer NumPy for Python 3.6b3?

[EDIT: Journal d'installation ajouté, après utilisation de Ensurepip]

D:\aaa\numpy-1.12.0b1>call C:\Python36\python.exe -m pip install numpy

    Note: if you need reliable uninstall behavior, then install
    with pip instead of using `setup.py install`:

      - `pip install .`       (from a git repo or downloaded source
                               release)
      - `pip install numpy`   (last Numpy release on PyPi)

Answer 1

Tant que les paquets binaires (appelés «roues») pour 3.6 ne sont pas encore disponibles pour PyPi, vous pouvez en utiliser des non-officiels (mais fonctionnants) disponibles sur http://www.lfd.uci.edu/~ gohlke/pythonlibs/ . Téléchargez le fichier et installez-le comme ceci:

pip install C:\path\to\numpy‑1.11.3+mkl‑cp36‑cp36m‑win_AMD64.whl

Answer 2

Pip lui-même ne fait pas partie de Python. Cependant, depuis la version 3.4, Python inclut le module ensurepip qui permet de démarrer une installation pip. Après avoir appelé

python3.6 -m ensurepip

vous devriez pouvoir installer numpy via pip.

Answer 3

Pip est toujours installé dans le sous-répertoire \Scripts du répertoire d'installation de Python 3.6.

Ouvrez la commande Invite dans Windows, changez le répertoire en \Scripts et saisissez pip list, vous verrez ce qui a été installé, puis saisissez pip install numpy et le numpy sera installé. 

Answer 4

Voici la liste des étapes à effectuer pour installer numpy sous Windows. Cela a fonctionné pour moi.

1. Définir la variable de chemin pour python - C:\Utilisateurs\XXXXXXX\AppData\Local\Programmes\Python\Python36-32
2. Télécharger le fichier get-pip.py localement
3. Ouvrez cmd et accédez au fichier get-pip.py
4. lancez python get-pip.py pour installer PIP
5. définir le chemin pip dans le chemin de la variable env - C:\Utilisateurs\XXXXXXX\AppData\Local\Programmes\Python\Python36-32\Scripts;
6. pip installer numpy

Answer 5

EDIT: J'ai mal interprété la question, je n'ai pas tenu compte de cette réponse.

Essayez manuellement téléchargez la roue de pypi et installez manuellement . Sous Windows, cela devrait ressembler à ceci:

C:/path/to/python36/pip.exe install C:/path/to/numpy_foo_.whl

Answer 6

Vous pouvez installer numpy via la commande Invite à l'aide de la commande pip install. Suivez les étapes ci-dessous: 1) Dans l'invite de commande, accédez au dossier de scripts de votre installation Python 3.x.

2) Tapez la commande suivante sur votre invite de commande

install numpy
