cannot visualize as pointclound

[ZoyeJay]

I runed the example.py, and it can show the depth map, but cannot visualize the pointclound. I installed the vtk on python3. and no error on "import vtk".

So please help me solve this error. Its about Cython? OR other? THANKS A LOT~

Yes, it seems to be about Cython and numpy.
Did you try to update numpy or Cython?

[ZoyeJay]

yes. The Cython version is 0.28.4 and the numpy version is 1.15.0. They are both the newest, but it still have the same error.
