尝试从热衷的mayavi模块导入mlab-获取“ RuntimeError：无法为qt4加载pyface.toolkits插件”

Question

The program starts with:-

from mayavi import mlab
from tvtk.tools import visual

and ends up with this message

>/Users/me/Library/Enthought/Canopy/edm/envs/User/lib/python3.5/si>te->packages/pyface/base_toolkit.py in import_toolkit(toolkit_name, >entry_point)
>    225     msg = msg.format(entry_point, toolkit_name)
>    226     logger.info(msg)
>--> 227     raise RuntimeError(msg)
>RuntimeError: No pyface.toolkits plugin could be loaded for qt4 

Answer 1

For licensing reasons, Canopy for Python 3.x does not ship with PyQt. Please install PyQt from the Canopy Package Manager, then try again. For more information, search the Enthought Knowledge base for pyqt python 3 , which will give you a link to this article: "Python 3 in Canopy 2 - 'No module named PyQt4' error" .
