是否有可能将mayavi 3d图集成到由pyqt5制作的gui中？ 在mayavi文档中，我发现了这一点： http://docs.enthought.com/mayavi/mayavi/building_applications.html，但是在运行代码时出现错误：“ RuntimeError：找不到用于工具箱qt5的traitsui.toolkits插件”。
代码如下：
# First, and before importing any Enthought packages, set the ETS_TOOLKIT
# environment variable to qt4, to tell Traits that we will use Qt.
import os
os.environ['ETS_TOOLKIT'] = 'qt4'
# By default, the PySide binding will be used. If you want the PyQt bindings
# to be used, you need to set the QT_API environment variable to 'pyqt'
#os.environ['QT_API'] = 'pyqt'
# To be able to use PySide or PyQt4 and not run in conflicts with traits,
# we need to import QtGui and QtCore from pyface.qt
from pyface.qt import QtGui, QtCore
# Alternatively, you can bypass this line, but you need to make sure that
# the following lines are executed before the import of PyQT:
# import sip
# sip.setapi('QString', 2)

是的，可以将mayavi 3d图整合到由pyqt5制作的gui中。不仅情节还可以显示动画！通过在您的GUI中的任何位置嵌入mayavi场景，几乎可以在PyQt5 Gui中完成使用单独的Mayavi窗口所做的所有操作。
如果您的代码与此链接完全相同：Qt embedding example。然后尝试在单独的文件中运行此代码，它应该可以工作。如果不是，则必须正确地重新安装库。
您可以参考下面的代码（简单版本），将mayavi嵌入到GUI中：
from PyQt5 import QtWidgets
import os
import numpy as np
from numpy import cos
from mayavi.mlab import contour3d
os.environ['ETS_TOOLKIT'] = 'qt4'
from pyface.qt import QtGui, QtCore
from traits.api import HasTraits, Instance, on_trait_change
from traitsui.api import View, Item
from mayavi.core.ui.api import MayaviScene, MlabSceneModel, SceneEditor
## create Mayavi Widget and show
class Visualization(HasTraits):
scene = Instance(MlabSceneModel, ())
@on_trait_change('scene.activated')
def update_plot(self):
## PLot to Show
x, y, z = np.ogrid[-3:3:60j, -3:3:60j, -3:3:60j]
t = 0
Pf = 0.45+((x*cos(t))*(x*cos(t)) + (y*cos(t))*(y*cos(t))-(z*cos(t))*(z*cos(t)))
obj = contour3d(Pf, contours=[0], transparent=False)
view = View(Item('scene', editor=SceneEditor(scene_class=MayaviScene),
height=250, width=300, show_label=False),
resizable=True )

QtGui.QWidget.__init__(self, parent)

self.visualization = Visualization()
self.ui = self.visualization.edit_traits(parent=self,
kind='subpanel').control
layout.addWidget(self.ui)
self.ui.setParent(self)

尝试在专用控制台中运行此代码。希望对您有帮助。
