 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-1.11.0-1.tar.bz2   18-Oct-2017 20:37       5.3M
 python-numpy-1.12.1+mkl-1.tar.bz2       10-Apr-2017 11:41       17M

 python-numpy-2.5-1.1.0-1.tar.bz2        22-Jun-2008 20:12       2.4M
 python-numpy-2.7-1.5.1-1.tar.bz2        07-May-2011 08:08       2.1M
 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?)
