Fix OutOfMemoryError

in Diffusers

Solution

OutOfMemoryError in diffusers primarily results from exceeding GPU memory capacity during large image generation or complex model operations. Fix this by reducing batch size, image resolution, or using techniques like memory-efficient attention (xFormers) and model offloading. Employ torch.cuda.empty_cache() periodically to clear unused memory and consider gradient checkpointing to reduce memory footprint.
