[pdal] PDAL and Jupyter (Newbie)

[Bradley Chambers]

Rereading your original post, am I correct in understanding that you have
Jupyter installed (perhaps even independent of Conda) and you are trying to
run the Conda commands to create and activate the environment within the
already running Jupyter notebook? I'm not sure that the Conda environment
is ever going to activate, at least not without jumping through some hoops
to make it happen.

The approach that I regularly use, which should work for you, is to create
your PDAL environment from the command line prior to starting Jupyter. Make
sure to install both PDAL and Jupyter to the environment, then activate it.
At this point you should be able to start Jupyter and import PDAL.
Something like this:

conda create --yes -n PDALenv -c conda-forge python-pdal jupyter
conda activate PDALenv
jupyter notebook
