Wrong location for filters.python and readers.numpy drivers #143

Closed ClementAlba closed 7 months ago

ClementAlba commented 1 year ago

Hi,

There is a little problem with the conda package python-pdal. Indeed, when I installed this package in a new env (with nothing inside of it) and tried to process a pdal pipeline containing a filters.python stage, I get this error : 

PDAL: Couldn't create filter stage of type 'filters.python'.
You probably have a version of PDAL that didn't come with a plugin
you're trying to load.  Please see the FAQ at https://pdal.io/faq

When the package is installed, the filters.python and readers.numpy drivers are stored in %CONDA_PREFIX%\bin, however the %PDAL_DRIVER_PATH% variable have this value : 

(test_pypdal) C:\>echo %CONDA_PREFIX%
D:\applications\miniforge3\envs\test_pypdal

(test_pypdal) C:\>echo %PDAL_DRIVER_PATH%
D:\applications\miniforge3\envs\test_pypdal\Library\bin;D:\applications\miniforge3\envs\test_pypdal\lib\site-packages\bin

So the drivers for filters.python and readers.numpy are not found. I was able to fix this problem by changing the value of the PDAL_DRIVER_PATH variable : 

set PDAL_DRIVER_PATH=%CONDA_PREFIX%\bin

Is it a normal behavior ?

PS: I'm on Windows 10 and I use conda 22.9.0
