render not work

I'm using bpy to render a 3D model into a PNG image. I have the same problem as #51, so I add the following code
bpy.context.scene.render.engine = 'CYCLES'

But the resulting image has a box in the middle. How should I change the code?
Thank you very much
I am also on Windows 10 x64 ,python 3.7

Sorry I'm not very familiar with Blender.
Thank you very much. It really helps.
