我尝试使用mayavi在jupyter笔记本中测试下面的示例来渲染音量
from mayavi import mlab
mlab.init_notebook()
x, y, z = np.ogrid[-10:10:20j, -10:10:20j, -10:10:20j]
s = np.sin(x*y*z)/(x*y*z)
mlab.pipeline.volume(mlab.pipeline.scalar_field(s))
我收到错误:
Notebook initialized with x3d backend.

我在anaconda中安装了Python 2.7,VTK 6.3,特性4.6。
答案 0 :(得分:1)
你安装了x3d吗?要安装扩展,mayavi doc提供的方法是
jupyter nbextension install --py mayavi --user
(见http://docs.enthought.com/mayavi/mayavi/tips.html#using-mayavi-in-jupyter-notebooks)。
这应解决问题。
