Fail to compile code for Lidar point cloud ground segmentation

[Jimuyangz]

Thanks for sharing the code! When I run preprocess.py, I have the following error:

Traceback (most recent call last):
File "preprocess.py", line 11, in
from lib.grndseg import segmentation
ImportError: cannot import name 'segmentation' from 'lib.grndseg' (unknown location)

Does it mean I didn't compile the code in lib/grndseg successfully? Thanks!

Yes that'd be my guess.

Yes. I had the same issue. For my case, it was caused by the `GLIBCXX_3.4.32' not found in my anaconda environment.
