hi i use code like this:
pZdroj = Con(pEfekt > 0, Con(IsNull(pZdroj), pEfekt, pEfekt + pZdroj), Con(IsNull(pZdroj), 0, pZdroj))
pZdroj.save('C:\\eee3')
pZdrojArray = arcpy.RasterToNumPyArray(pZdroj)
del pZdroj
and I have unexpected error on Raster.save method,, but when i skip it, i create array from raster whit no problem (equation is OK there is no problem whit it in raster calculator).. so any suggestion whit this problem? (when i use equation like this Con(pEfekt > 0, Con(IsNull(pZdroj), pEfekt, 1), Con(IsNull(pZdroj), 0, 1)) i haven´t problem whit save method)
