AI绘画——使用stable-diffusion生成图片时提示RuntimeError: CUDA out of memory处理方法

提示显存不足

RuntimeError: CUDA out of memory. Tried to allocate 1.50 GiB (GPU 0; 8.00 GiB total capacity; 5.62 GiB already allocated; 109.75 MiB free; 5.74 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

1、添加参数–n_samples 1，其默认值为3

python scripts/txt2img.py --prompt “a photograph of an astronaut riding a horse” --plms –n_samples 1

2、降低精度

修改scripts/txt2img.py文件，在model.to(device)后添加.half()

3、结果<
