RuntimeError: call execute() before fetching arrays

While trying to execute below line:

arr = pipeline.arrays[0]

Getting below error:

PCL_UTILS cannot be imported

Hello,

I'm new to pcl. While redoing the work u uploaded, I have an issue. In my Mac, I have both pcl and python-pcl. But in your code, u import an package at the very beginning which is pcl_utils. I'm just wondering what the package is and how could I install.

Much appreciates.

Sincerely,
Rowen

Issue open creating 3D model ?

Hi everyone,

First of all thank you for the notebook it is really interesting. I try to understand all the notebook "point-cloud-processing-static.ipynb", but it doesn't work on the creation of 3D model if I take another building, or several buildings.
For example :

It gives me something like that :

I'm sure I have to change the Build 3D model in rotated coordinates and Plot 3D model parts, but for now it doesn't work.
