James -
I'm currently running python-pdal version 2.1.8 and pdal version
1.8.0. Not sure if those are mismatched or where I would check that. Conda
doesn't seem to report any issues.
Andrew -
I get the following traceback which is what I attempted to use to
understand the file structure on the Github. However, it doesn't seem very
verbose.
