按照教程,完全运行不起来,你还能运行的起来
更新ppdiffusers、pip install -U ppdiffusers
你好,建议使用ppdiffusers目录下的代码运行,当前appflow可能会存在问题 (你使用的代码采用了float32精度,未开启xformers,默认生成图片大小为768x768,这些原因会导致你在16G显卡上无法正常运行!)。

下面的命令使用了
显存占用:
import paddle
from ppdiffusers import StableDiffusionPipeline
pipe = StableDiffusionPipeline.from_pretrained("runwayml/stable-diffusion-v1-5", safety_checker=None, paddle_dtype=paddle.float16)
# 如果无法使用xformers,请注释下面的内容。
pipe.enable_xformers_memory_efficient_attention()
prompt = "a photo of an astronaut riding a horse on mars"
image = pipe(prompt, height=512, width=512, guidance_scale=7.5).images[0]
image.save("text_to_image_generation-stable_diffusion-result.png")
Out of memory error on GPU 0. Cannot allocate 5.062500GB memory on GPU 0, 12.043945GB memory has been allocated and available memory is only 2.956055GB.
官方demo:
from paddlemix import Appflow import paddle paddle.seed(1024) task = Appflow(app="text2image_generation", models=["stabilityai/stable-diffusion-v1-5"] ) prompt = "a photo of an astronaut riding a horse on mars." result = task(prompt=prompt)['result']
