When I try to import pdal, I have this error:

>>> import pdal
Traceback (most recent call last):

As QGIS provides PDAL 2.3.0, maybe you should use PDAL==2.3.0 for pypi package ​https://pypi.org/project/PDAL/2.3.0/

Instead of latest

Import works from python-qgis.bat but not from embedded python console in QGIS with python-pdal 3.0.2-1

Not reproducable - in a fresh install of qgis-full with python-pdal I can load pdal in the python console just fine.

[nicogodet]

Import fails when QGIS is started using .exe Import OK when QGIS is started using .bat

[jef]

Doesn't seem to make any difference here either.

[nicogodet]

Yeah, local issue not linked to my qgis install (which is fresh) but my computer or dunnow...

OK on another computer with with .bat and .exe.

You can close this.
