Out of memory error with subsequent generations
I have a 24VRAM graphic card and i can upscale just fine with the tiled diffusion + Noise inversion + Controlnet tile method but if i try to upscale again even not touching anything in the UI i get an Oom error everytime until i close stable diffusion, and try again when it works for the first generation only and so on. if i reduce the scale factor from 2 to 1.5, so it needs less RAM, it works, so maybe there are traces that doesn't get unloaded from the VRAM after using this extension?
My generation parameters:
Steps: 50, Sampler: Euler, CFG scale: 12, Seed: 979277642, Size: 2304x1664, Model hash: 4199bcdd14, Model: revAnimated_v122, Denoising strength: 0.75, Clip skip: 2, ENSD: 31337, Version: v1.2.1, Tiled Diffusion upscaler: 4x_foolhardy_Remacri, Tiled Diffusion scale factor: 2, Tiled Diffusion: "{'Method': 'Mixture of Diffusers', 'Tile tile width': 64, 'Tile tile height': 64, 'Tile Overlap': 32, 'Tile batch size': 8, 'Upscaler': '4x_foolhardy_Remacri', 'Upscale factor': 2, 'Keep input size': True, 'NoiseInv': True, 'NoiseInv Steps': 30, 'NoiseInv Retouch': 1, 'NoiseInv Renoise strength': 0, 'NoiseInv Kernel size': 64}", ControlNet 0: "preprocessor: tile_resample, model: control_v11f1e_sd15_tile [a371b31b], weight: 1, starting/ending: (0, 1), resize mode: Crop and Resize, pixel perfect: True, control mode: Balanced, preprocessor params: (64, 2, 64)"
I think this may be an issue in control net. But I’m not sure. Will check in detail when I have time.
Well I get the same issue, after upscale to 8k I upscale another image to 2k and get OOM message
Get OOM error when I use tile resampling + realistic lineart or coarse lineart preprocessor But tile + lineart anime prep work as it should. Settings are the same Tiled diffusion will still run despite of the error but as if no model applied.
Not sure if this is controlNet or tiled diffusion problem but this only has happened in recent updates as I tried this same setup awhile ago.
You may try to disable the live preview.
Still doesn't work. It happens randomly. I think it has something to do with recent nvidia update. As workaround, i just make a lineart map and set preprocessor to none.
