So I have a python script that uses numpy to calculate the mean of a field, then I try to use that mean value in a raster multiplication as follows: na = arcpy.da.TableToNumPyArray("%SCRATCHWORKSPACE%\\rc_instruments_sr_noNULL2", "ratio") dMeanRatio = numpy.mean(na["ratio"])...

I have installed GeoServer from OpenGeo Suite 4.1 on a fresh Unbuntu 12.04 following Boundless instructions. Now I wanted to test geoscript-groovy, and installed groovy, geoscript-groovy-1.3.1, geoserver-2.5.2-wps-plugin and geoserver-2.5-SNAPSHOT-groovy-plugin (community, 10-15-2014), with...
