make_image_grid([init_image, depth_image], rows=1, cols=2) Load a ControlNet model conditioned on depth maps and the AutoPipelineForImage2Image: Copied from diffusers import ControlNetModel, AutoPipelineForImage2Image

make_image_grid([init_image, depth_image, image_control_net, image_elden_ring], rows=2, cols=2) Optimize Running diffusion models is computationally expensive and intensive, but with a few optimization tricks, it is entirely possible to run them on consumer and free-tier GPUs. For example, you can use a more memory-e...
+ pipeline.enable_xformers_memory_efficient_attention() With torch.compile, you can boost your inference speed even more by wrapping your UNet with it: Copied pipeline.unet = torch.compile(pipeline.unet, mode="reduce-overhead", fullgraph=True) To learn more, take a look at the Reduce memory usage and Torch 2.0 guides...
