arcpy.NumpyToRaster fails with error two or three dimensional NumPy array is required

The following code:


arcpy.AddMessage("shape of zOutput {} ".format(zOutput.shape))
arcpy.AddMessage("no of dimensions of zOutput {}".format(zOutput.ndim))
# Convert array to a geodatabase raster
myRaster = arcpy.NumPyArrayToRaster(zOutput, arcpy.Point(xmin,ymin), cellsize, cellsize, -999999)


produces the following output. As you can see the numpy array IS two dimensional. Yet NumPyArrayToRaster fails.




shape of zOutput (375, 524)
no of dimensions of zOutput 2
ValueError: Argument in_array: A two or three dimensional NumPy array is required.




Is this a bug in NumPyToRaster?  Is there some other way to export a numpy array to a raster?
