python - mlab mayavi

instalando Mayavi con pip-no hay módulo llamado vtk

Question

Quiero usar Mayavi.

Situación

• Yo uso un MacBook Air, con OSX 10.7.3.
• Yo uso Python 2.7.2
• Tengo virtualenv instalado. Pero no lo he usado para esta instalación.

He instalado manualmente todas sus dependencias, incluyendo VTK .

Para VTK , seguí su guía de instalación e instalé la envoltura de python.

Ahora, si abro una nueva ventana de terminal y abro Python, puedo importar vtk sin ningún error.

Problema

Intento instalar Mayavi con el siguiente comando:

pip install mayavi

Pero se produce el siguiente error:

Creo que el problema es con vtk .

¿Alguien puede ayudarme?

Otros detalles

Ejecutar sudo pip install mayavi no resuelve el problema.

Answer 1

Es probable que su pip esté usando un python diferente, una especie de vtk instalado usando /usr/local/bin/python , mientras que su binario pip usa /usr/bin/python .

Revisalo:

$ head -n1 $(which pip)

Para resolverlo, puedes elegir usar un virtualenv o instalar pip usando /usr/local/bin/python :

curl https://raw.github.com/pypa/pip/master/contrib/get-pip.py | /usr/local/bin/python

Para obtener más instrucciones de instalación, consulte http://www.pip-installer.org/en/latest/installing.html

Answer 2

Estoy en Debian pero esto debería funcionar para ti también

Me quedé atascado con la instalación de vtk en un virtualenv, después de horas de búsqueda sin resultados, hice lo siguiente y funcionó.

1. instala python-vtk desde repositorios de todo el sistema

2. copie la carpeta vtk de /usr/lib/pymodules/python2.7 a /PATH/TO/YOUR/VIRTUALENV/lib/python2.7/site-packages

En su caso, la carpeta de paquetes de python de todo el sistema probablemente sería diferente, pero puede encontrarla fácilmente activando el sistema python e ingresando lo siguiente:

import vtk,sys
print(sys.modules[''vtk''])

Después de este truco, mayavi se instaló con éxito en mi virtualenv usando pip install mayavi y pip install imagine.

Edición: en lugar de copiarlo, es mejor que solo se vincule simbólicamente la carpeta en el paso 2

Answer 3

Insistí en instalar sudo varias veces, finalmente lo resolví, no sé cómo explicarlo.

sudo python2 -m pip install mayavi

sudo python3 -m pip install mayavi

Answer 4

Instalé vtk utilizando Homebrew:

$ brew install vtk

espero que esto ayude.

Answer 5

Tuve el mismo problema al instalar mayavi con python instalado en pyenv, y resolví este problema copiando el directorio en /home/myname/.pyenv/versions/2.7.12/lib/python2.7/site-packages , a continuación está mi método:

1. instalar vtk y python-vtk

   sudo apt-get install vtk6
   sudo apt-get install python-vtk

2. prueba python -c "import vtk" , si falla nuevamente, ve al paso 3

3. el error de importación puede deberse a la pérdida de la carpeta del paquete vtk en su python actual, por lo que deberíamos encontrar la carpeta vtk y copiarla en el directorio de python actual (lo más posible el python en el directorio de pyenv shims).

   la ruta de la carpeta vtk en mi ubuntu es

   /usr/lib/python2.7/dist-packages/vtk

   simplemente copie la carpeta vtk a los /site-packages python actuales, por ejemplo,

   cp -r /usr/lib/python2.7/dist-packages/vtk /home/myname/pyenv/versions/2.7.12/lib/python2.7/site-packages

4. intente python -c "import vtk" nuevo.

5. Si no hay error de importación, simplemente hazlo.

   pip install mayavi

Answer 6

Tuve el mismo problema y la primera respuesta no me ayudó porque pip estaba en el directorio correcto, pero resultó que no tenía instalado vtk - ejecutando sudo apt-get install python-vtk solucioné el problema y pude para ejecutar con éxito pip instalar mayavi después de eso.
