Public bug reported:
When using the GDAL python API (package pyhon3-gdal), attempting to access the
data type of a loaded raster's band (via the property DataType) throws the
exception:
"in method 'Band_DataType_get', argument 1 of type 'GDALRasterBandShadow *'"
The issue was limited (in my case) to Ubuntu 24.04. Discovered on a
month-old installation, and reproduced on a second machine using the
Ubuntu live (running from a thumb drive) environment with freshly
fetched packages (version 3.8.4+dfsg-3ubuntu3).
When running the same test code on an Ubuntu 22.04 installation (latest
available python3-gdal version is 3.4.1+dfsg-1build4) for the same
raster, it produces the correct output without throwing any exceptions.
A simple python code to test this:
---------------------------------------------------------------------------------------------------
from osgeo import gdal
from osgeo.gdalconst import GA_ReadOnly
try:
rasterDataType = gdal.Open("/path/to/some/raster",
GA_ReadOnly).GetRasterBand(1).DataType
except Exception as e:
print(e)
---------------------------------------------------------------------------------------------------
Several datasets were used in testing. e.g. Landast 8 Collection 2 Level 2
rasters, obtained from https://earthexplorer.usgs.gov
(P.S: This is my first ever bug report. Would appreciate the patience and
advice regarding any mistakes or missing information. This report was initiated
using ubuntu-bug, unless I misunderstood the process, it collects and includes
all the relevant version/package information)
