Installing GeoPandas breaks pdal

Installing GeoPandas breaks pdal

maboualidev opened this issue 5 months ago · comments

Hi,

I create an enviroment using conda installing the following packages (All from conda-forge):

python=3.11
pdal
python-pdal
gdal

pdal will work up to this point.

However, the moment I install geopandas using conda install -c conda-forge geopandas then pdal stops working:

Python 3.11.8 | packaged by conda-forge | (main, Feb 16 2024, 20:40:50) [MSC v.1937 64 bit (AMD64)] on win32
Type "help", "copyright", "credits" or "license" for more information.
>>> import pdal
Traceback (most recent call last):
  File "<stdin>", line 1, in <module>
  File "C:\miniconda3\envs\env_name\Lib\site-packages\pdal\__init__.py", line 4, in <module>
    from . import libpdalpython
ImportError: DLL load failed while importing libpdalpython: The specified module could not be found.

Not sure if this helps, but when installing geopandas I see this message:

The following packages will be DOWNGRADED:

  gdal                                3.8.4-py311h21a6730_6 --> 3.8.4-py311h21a6730_5
  geotiff                                 1.7.1-hed9d743_16 --> 1.7.1-hbf5ca3a_15
  libgdal                                  3.8.4-hbda495f_6 --> 3.8.4-hf83a0e2_5
  libspatialite                            5.1.0-hf13de1f_5 --> 5.1.0-hf2f0abc_4
  proj                                     9.4.0-he13c7e8_0 --> 9.3.1-he13c7e8_0

any idea how to fix?

Downgrading pdal to 2.5.6 solves the issue, seems the issue is with 2.7.1

pdal 2.7.0 also crashes, but a different error pops up

2.6.3 also crashes. Some other error though, the same as 2.7.0.

Seems the version of pdal that does work with geopandas is 2.5.6

Cannot replicate on osx-arm64.

The Geopandas Conda Forge recipe has not been rerendered in quite a while, and it has a hard pin on Fiona 1.8.21, which I suspect has windows-specific pins for its dependencies.

I think you are in DLL hell here, basically.

Yeah, the issue is on windows only. Doesn’t happen on linux either

Replicated at PDAL/python#164 (comment) not sure what I can do to fix it, however.

After some investigation, it was shown this issue was due to a PROJ version pin in pyproj. Please retest to confirm things are now working.
