[gdal-dev] gdal docker with numpy2-compatible python bindings

[Vincent Schut]

Hi, the current gdal-ubuntu-small docker (3.9.1) appears to have python 
bindings that are not compatible with numpy 2.0.0. If I pip install 
--upgrade numpy==2.0.0 and then try `from osgeo import gdal, gdal_array` 
I get an error:

In [4]: from osgeo import gdal, gdal_array

A module that was compiled using NumPy 1.x cannot be run in
NumPy 2.0.0 as it may crash. To support both 1.x and 2.x
versions of NumPy, modules must be compiled with NumPy 2.0.
Some module may need to rebuild instead e.g. with 'pybind11>=2.12'.

If you are a user of the module, the easiest solution will be to
downgrade to 'numpy<2' or try to upgrade the affected module.
We expect that some modules will need time to support NumPy 2.

I hoped that the python bindings in the docker image would be compatible 
with both numpy 1 and 2, but apparently they're not? Would it be 
possible to create docker images with bindings that are compatible with 
numpy2? Or would you rather wait until the official ubuntu numpy package 
moves to 2.0?

Thanks,
