How to get and set the fx and fy of the camera from the test-rendering？

[jiajialu1995]

Is there any way to get or set the parameter of the camera in test-rendering (python file). And the which kind of device in parser.add_argument('--device', type=int, default=0) can be set?

1. Camera internal matrix #42

2. device is an integer. It means which GPU to use.
