I tried to run the old python code that rendered images using bpy,then I got this error:
AttributeError: 'RenderSettings' objects has no attribute 'alpha_mode' blender quit
I tried to install the oldest version of bpy, but the result did not change.
I noticed that since Blender has changed a lot since version 2.8 blender version, the version of Blender installed on the OS needs to be changed to 2.7, so I first uninstalled the previously installed Blender, then installed Blender 2.79 download links.
