 Hi,

 on a clean windows 32 bit build, if installing msys, gdal, gdal-python,
 python and python-numpy:

 open msys

 $ python
 Python 2.7.14 (v2.7.14:84471935ed, Sep 16 2017, 20:19:30) [MSC v.1500 32
 bit (Intel)] on win32
 Type "help", "copyright", "credits" or "license" for more information.
 >>> import numpy
 >>> from osgeo import gdal
 >>> from osgeo import gdalnumeric
 RuntimeError: module compiled against API version 0xc but this version of
 numpy is 0x7
 Traceback (most recent call last):
   File "<stdin>", line 1, in <module>
   File "C:\OSGeo4W\apps\Python27\lib\site-packages\osgeo\gdalnumeric.py",
 line 2, in <module>
     from osgeo.gdal_array import *
   File "C:\OSGeo4W\apps\Python27\lib\site-packages\osgeo\gdal_array.py",
 line 17, in <module>
     _gdal_array = swig_import_helper()
   File "C:\OSGeo4W\apps\Python27\lib\site-packages\osgeo\gdal_array.py",
 line 16, in swig_import_helper
     return importlib.import_module('_gdal_array')
   File "C:\OSGeo4W\apps\Python27\lib\importlib\__init__.py", line 37, in
 import_module
     __import__(name)
 ImportError: No module named _gdal_array
 >>> exit()

 In OSGEo4w, the only option is to download python-numpy version 1.7.0, and
 the alternate version is 1.5, although these are very old, and the latest
 versions under osgeo seem to be 1.12 and 1.15.

 This appears to be because the python version is included in the file
 names of the older packets versions on the download site, making them seem
 as if they are newer.

 python-numpy-2.7-1.7.0-1.tar.bz2        28-May-2013 15:10       2.4M

 The result of the error is that matplotlib and pandas will no longer
 function, since 1.7 is below their minimum versions, and also any script
 using gdal_calc, the gdal raster calculator, will also fail.

 Is there a workaround for this?  Can I make the setup look for the right
 version (which is probably 12?)

 Thanks,
