ModuleNotFoundError: No module named 'traitsui.null'

[Roly83]

hola me gusta mucho mayavi y estoy tratando de utilizarla y aprender todo lo que pueda sobre ella. Estoy realizando un proyecto que al convertirlo en un ejecutable para Windows me genera el siguiente error. Por favor si alguien pudiera ayudarme a resolverlo:

Traceback (most recent call last):

ModuleNotFoundError: No module named 'traitsui.null'

The above exception was the direct cause of the following exception:
