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.

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()
