Interaction geopandas / PDAL python 3.8

[NanBlanc]

Hi, I just stumble on this problem : installing geopandas alongside pyhton-PDAL provoc the following error :

(PDAL Error) Can't load library /home/ostocker/miniconda3/envs/folitd38/lib/libpdal_plugin_reader_draco.so: Failed to load "/home/ostocker/miniconda3/envs/folitd38/lib/libpdal_plugin_reader_draco.so": libdraco.so.8: cannot open shared object file: No such file or directory

To recreate it on Ubuntu 20.04 :

1. conda create -n new_env python=3.8
2. conda activate new_env
3. conda install -c conda-forge geopandas
4. conda install -c conda-forge python pdal
5. python
6. import geopandas
7. import pdal

Installing only pdal will not produce this import error

The easiest workaround I found is to use python=3.7

I'm working it. Conda stuff needs to be rerendered. Pin to older versions of python-pdal

ah, you need the older version of draco for PDAL 2.5.5, which is what gets dragged in when you pin everything to geopandas

conda install draco=1.5.6
