两个文件随便下载一个就可以。重命名为model.ckpt,保存到\stable-diffusion\models\ldm\stable-diffusion-v1 目录下面

这个确实很坑，默认里diffusers版本太高
解决方法：
conda list 查看diffusers版本，为0.14.0.
将这个删掉，
pip uninstall diffusers
重新安装0.12.1版本
pip install diffusers==0.12.1
或者在创建环境时直接修改 environments.yaml, "diffusers" --> "diffusers==0.12.1"
如果提示：TimeoutError: [WinError 10060] 由于连接方在一段时间后没有正确答复或连接的主机没有反应，连接尝试失败。
网络问题，多试几次就好。
如果提示RuntimeError: CUDA out of memory.，加个参数 --n_samples 1
