Workaround

z[:,::-1] creates a view of the array. NumPyArrayToRaster requires a NumPy array object.1) Pass np.array(z[:,::-1]) which creates a new copy of the array.ex. grid1=arcpy.NumPyArrayToRaster( np.array(z[:,::-1]),xyOrig,np.abs(dx),np.abs(dy))2) Use the .copy() method to create a new copy of the reorder array.ex. grid1=arcpy.NumPyArrayToRaster(z[::-1,:].copy(),xyOrig,np.abs(dx),np.abs(dy))
