de Windows + virtualenv + pip + NumPy (problemas al instalar NumPy)

Question

En Windows, que normalmente sólo tiene que utilizar el instalador binario, pero me gustaría instalar NumPy sólo en un virtualenv este tiempo, así que crearon un env virtual:

virtualenv --no-site-packages --distribute summary_python 
cd summary_python/Scripts 
activate.bat 

Luego he intentado instalar NumPy

pip install numpy 

y me sale un error. Mi pip.log se pega a continuación:

Answer 1

He tenido éxito instalando binarios NumPy en un virtualenv con un buen 'ol easy_install y un poco de magia para archivar.

El numpy-1.x.x-win32-superpack-python2.x.exe liberación que se descargan de SourceForge es realmente sólo un envoltorio fino alrededor de tres distribuciones binarias separadas (con SSE3, SSE2, o ninguna SSE habilitado, dependiendo de la capacidad de la CPU). Si abre el archivo EXE superpack en 7-Zip (u otra utilidad de archivo), puede extraer esos archivos de configuración individuales en algún lugar para utilizarlos por separado.

A continuación, active su entorno virtual, y correr

easy_install c:\path\to\extracted\numpy-1.x.x-sse3.exe 

para instalar los binarios SSE3 optimizados, por ejemplo. easy_install es lo suficientemente inteligente como para encontrar todo lo que necesita dentro de ese paquete wininst y extraerá el compilado egg en la carpeta de paquetes de sitio de su virtualenv. También puedo confirmar que pip todavía puede reconocer y/o desinstalar NumPy cuando haces esto, y que usar pip para instalar otros paquetes que dependen de NumPy funciona bien.

El único inconveniente es saber qué nivel de optimización usar (SSE3, SSE2 o no SSE). Si tiene un reasonably modern processor (más reciente que, por ejemplo, un Pentium 4 o Athlon 64), probablemente sea seguro ir con el SSE3 completo. Probablemente también pueda ejecutar el conjunto de pruebas para confirmar que todo funciona como se espera.

---

que he encontrado el "truco" easy_install a ser realmente útil para la instalación de todo tipo de paquetes binarios en un virtualenv. Aunque tengo todos los compiladores necesarios configurados en mi máquina, generalmente es más fácil/más rápido/más seguro seguir con el lanzamiento oficial cuando se proporciona uno.

Answer 2

Desde PIP sólo se puede instalar desde el código fuente, es necesario tener la configuración para crear y compilar NumPy para poder utilizar PIP. Nunca intenté esto.

Lo que hice recientemente para obtener NumPy, SciPy y Matplotlib en un entorno virtual en Windows 7   es copiar los directorios y archivos de mi egg Python instalación regular directamente en el entorno virtual. Para Matplotlib, también pude descomprimir el instalador binario directamente en el virtualenv (solo intenté esto para el instalador de Gohlke para Python 3.2).

Lo logré en el pasado para easy_install NumPy en un virtualenv de una distribución binaria, pero esta vez no lo logré (NumPy 1.5.1).

Alguien recomendó http://pypi.python.org/pypi/pyg que debería permitir la instalación desde paquetes binarios a un virtualenv, pero aún no lo he probado.

Answer 3

No tuve que hacer el truco de desempacar el archivo .exe. Acabo de activar mi entorno virtual, y luego:

easy_install numpy
