Minimum gpu memory requirement

[Babylonehy]

Hi, I tried to run the demo on RTX2060 6G, unfortunately ran out of gpu memory, so I want to know what is the minimum GPU memory requirement?

GPU:0 with 591 MB memory) -> physical GPU (device: 0, name: GeForce RTX 2060, pci bus id: 0000:09:00.0, compute capability: 7.5)
Restoring checkpoint ./model/ring_6_68641..
218
Resizing so the max image size is 224..
