我想用彩色图像一起绘制3D数据，以Mayavi为3D图，以OpenCV（cv2.imshow）为图像。
（实际上，我的真正目标是动画，例如CAMERA图像显示的一个窗口和LIDAR 3D点云显示的一个窗口。在这个问题上，让我们放下动画部分。）
使用以下代码，我可以可视化3D图。
from __future__ import absolute_import, division, print_function
import numpy as np
from mayavi import mlab
fig = mlab.figure(figure=None, bgcolor=(0,0,0), fgcolor=None, engine=None, size=(500, 500))
axes = np.array([[2.,0.,0.,0.], [0.,2.,0.,0.], [0.,0.,2.,0.]],dtype=np.float64)
mlab.plot3d([0, axes[0,0]], [0, axes[0,1]], [0, axes[0,2]], color=(1,0,0), tube_radius=None, figure=fig)
mlab.plot3d([0, axes[1,0]], [0, axes[1,1]], [0, axes[1,2]], color=(0,1,0), tube_radius=None, figure=fig)
mlab.plot3d([0, axes[2,0]], [0, axes[2,1]], [0, axes[2,2]], color=(0,0,1), tube_radius=None, figure=fig)
mlab.show()
import pdb; pdb.set_trace() # <-- Just to keep window open
但是，当我仅添加一行import cv2时，程序将因段错误而失败。

当然，仅使用“ cv2”（不使用mayavi）可以完美运行。
这是计算机设置问题吗？还是本机禁止的？
我怎样才能在Mayavi窗口中添加一个额外的cv2.imshow窗口？
