Comment installer numpy avec pip + mingw dans windows?

J'ai pip+mingw sous windows. Je l'ai testé avec

pip install cython

et il fonctionne parfaitement.

pip install numpy

échoue cependant avec une longue liste de messages d'erreur. Quelle est la manière correcte de le faire ou dois-je essayer avec le pip?

pip est la construction de Numpy à partir de la source et c'est tout à fait une entreprise. L'échec à la fin me dit que vous ne pouvez pas avoir votre compilateur correctement configuré pour distutils. J'utilise le SDK de Windows compilateur moi-même: http://www.microsoft.com/en-us/download/details.aspx?id=8279

Si vous utilisez cette option, vous devez définir les variables d'environnement:
```
set MSSdk=1
set DISTUTILS_USE_SDK=1
```
Cela dit, il est beaucoup plus facile à installer Numpy et Scipy à l'aide de l'un de la .msi installateurs qui vous pouvez trouver ici: http://scipy.org/Download.
Numpy s'appuie sur l'BLAS bibliothèques d'algèbre linéaire et de la génération de ceux qui est très technique et une accumulation de Numpy à partir de la source sous Windows, il vaut mieux éviter, sauf si vous avez une bonne raison de le faire.
