无法加载包'enthought.mayavi.mlab'

Question

我正在尝试在python的蜘蛛环境中加载软件包enthought.maya .mlab:

import enthought.mayavi.mlab as mlb

，我得到以下错误信息:

    sip.setapi('QString', 2)
ValueError: API 'QString' has already been set to version 1

有人知道怎么修理它吗?编辑:如果有帮助的话，我认为这个问题已经在最后一栏中解释了:

ValueError: API 'QString' has already been set to version 1

编辑:我试着改变API选择的QString和QVariant对象API #1，#2。没有帮助。尝试将"忽略API更改错误"设置为true，但没有帮助。尝试EST_TOOLKIT从'qt4'到'wx'.

这可能是因为spider本身使用QT库并且已经初始化了它。根据这个http://pythonhosted.org/spyder/installation.html你可以使用PySide而不是PyQt4(但我不知道这是一个配置选项还是一个回退)。
