Unable to run the example ipynb file

I am trying to run the example python program given by Open3D

#jupyter nbconvert --to python multiway_registration.ipynb
and getting multiway_registration.py, Now i run this program

#python multiway_registration.py and getting the below error.

Traceback (most recent call last):
File “multiway_registration.py”, line 46, in

File “…/open3d_tutorial.py”, line 47, in jupyter_draw_geometries
