我正在尝试在 python 的蜘蛛环境中加载包 enthought.mayavi.mlab：
import enthought.mayavi.mlab as mlb
我收到以下错误消息：

sip.setapi('QString', 2)
ValueError: API 'QString' has already been set to version 1
有人知道如何解决吗？编辑：如果有帮助，我认为问题已在最后一栏中得到解释：
ValueError: API 'QString' has already been set to version 1
编辑：我尝试将 QString 和 QVariant 对象的 API 选择更改为 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。尝试从 'qt4' 到 'wx' 的 EST_TOOLKIT。
