When use mlab.figure， got error "AttributeError: type object 'Unimplemented' has no attribute 'process_events'"

I am using the code of OccNerf, and got error as follows:

  figure = mlab.figure(size=(render_w, render_w/16*9), bgcolor=(1, 1, 1))
  File "/opt/conda/lib/python3.8/site-packages/mayavi/tools/figure.py", line 69, in figure
    engine.new_scene(name=name, size=size)

It means GUI has no attribute named "process_events", which version of mayavi should I install?

It means GUI has no attribute named "process_events", which version of mayavi should I install?

Metoo, any ideas now?

Commenting out that line in the common.py can solve the problem. I've tried and it seems ok for me.
`def process_ui_events():
"""Process GUI events.

This function merely abstracts the function so nothing is done when
no UI is running.
"""
if pyface is not None:
    # pyface.GUI.process_events()
    pass

`
btw, version 4.8.1 is ok, but I haven't tried it.

AttributeError("module 'mayavi' has no attribute 'figure'")
