[pdal] PDAL install

Fri Apr 24 08:28:49 PDT 2020

Thank you, Mike, Howard and Adam for all your help.
I will explain more the complexity that went on with all the softwares
involved: Anaconda comes with 2, one with Python 2.7, and one with Python
3.7. I used to use Anaconda with Python2, and then with the addition of
Python3, I tried to create virtual env for both with the Anaconda.
Researched and tried various methods, but none works with the Anaconda
setup. But ArcGIS still uses python2.7 so I uninstall Anaconda with
Python2. REinstall ArcGIS which imports Python2 in the backdrop. I
reinstall Anaconda with 3.7. To upgrade to Python3.8 via conda, need to
upgrade conda, then use it to import 3.8. Processed but nothing happen.
REad others with similar issues. Uninstall Anaconda and install Python3.8
on its own. Everything works fine. Now I'm using GRASS GIS for project. Can
use ArcGIS but GRASS is efficient for Lidar processing but its libLAS that
it bases on doesn't support minor version higher than 1.2 and the LAS file
I import for project has minor version greater than that. Read two tools
that can help: LAStools and PDAL. Know one PDAL module can be run in GRASS,
but PDAL cannot be imported using pip, just conda.

I look at Adam's Anaconda link, if you look at the files section, you
cannot find a windows python3.8 edition. I understand Mike's way of
importing PDAL over Python3, but Python doesn't come with conda installed
and I am back to square one. Here's what I will do rather than poke around
as this is getting way too long: I will uninstall python3.8 and reinstall
Anaconda. Once the project is over, I can research and reconfigure.

I completely understand why PDAL has to install over conda base off Adam's
email. This conversation provides great insight and I thank you for your
time.

Have a great day!
