CUDA out of memory

[Astraha]

torch.cuda.OutOfMemoryError: . Tried to allocate 20.00 MiB (GPU 0; 6.00 GiB total capacity; 5.28 GiB already allocated; 0 bytes free; 5.34 GiB reserved in total by PyTorch) If reserved memory is >> allocated memory try setting max_split_size_mb to avoid fragmentation. See documentation for Memory Management and PYTORCH_CUDA_ALLOC_CONF How can i fix it ?

use cpu, or --lowvram, or simply reduce img resolution 🤷🏿

I ended up using the "optimized" scripts from https://github.com/basujindal/stable-diffusion (I have 6GB of VRAM). The maximum output is ~ 512x512

try to use --xformers and use both --lowvram and --medvram

resolution is also a key factor so you can generate image at minimal resolution and upscale it
