module 'pclpy.pcl' has no attribute 'visualization'

[micdist]

Hi, thanks for all this great work, I have an issue but I don't know if it is anything with your code. In the visualization part of your tutorial you use " viewer = pclpy.pcl.visualization.PCLVisualizer("3D viewer") " but than it provokes: AttributeError: module 'pclpy.pcl' has no attribute 'visualization'

I must say that when importing from pclpy import pcl I have an error on pcl: Cannot find reference 'pcl' in 'init.py'

Thank you for any help you shall provide.
