I would like to capture or show GDAL error messages in an interactive<br>
Python shell. For instance, if trying to open an non-existing raster:<br>
<br>
from osgeo import gdal<br>
ds = gdal.Open('noexist.tif')<br>
<br>
shows nothing in an interactive shell (PythonWin, IDLE), but shows<br>
messages when used in a shell (cmd.exe or Bash):<br>
<br>
ERROR 4: `noexist.tif' does not exist in the file system, and is not<br>
recognised as a supported dataset name.<br>
<br>
It appears this output is sent to stderr. How can this output also<br>
appear in an interactive Python shell, such as PythonWin or IDLE?<br>
<br>
Thanks,<br>
