python diffusers StableDiffusionXLPipeline 离线使用_v1-5-pruned-emaonly.safetensors 下载

下载sd_xl_base_1.0.safetensors

https://huggingface.co/runwayml/stable-diffusion-v1-5/tree/main

我这下载后放到项目 models 里

model_path = "./models/v1-5-pruned-emaonly.safetensors"
# model_path = "./models/v1-5-pruned.safetensors"
# modelId = "runwayml/stable-diffusion-v1-5"
if Util.isMac():
    # from_single_file
    pipe = StableDiffusionPipeline.from_single_file(model_path, original_config_file='./models/v1-inference.yaml', cache_dir='./cache/', use_safetensors=True)
    pipe = pipe.to("mps")
    pipe.enable_attention_slicing()
else:
    pipe = StableDiffusionPipeline.from_single_file(model_path, torch_dtype=torch.float16, use_safetensors=True)
    pipe.to("cuda")
    pipe.enable_model_cpu_offload()
    pipe.enable_attention_slicing()

修改package

Diffusers 里代码写死了会访问 huggingface，需要手工改掉

 
 
import sysconfig; 
 
def repalceStringInFile(srcStr, dstStr, filePath):
    # Read in the file
    with open(filePath, 'r') as file:
        filedata = file.read()
 
    # Replace the target string
    filedata = filedata.replace(srcStr, dstStr)
 
    # Write the file out again
    with open(filePath, 'w') as file:
        file.write(filedata)

http://xxxxxx 需要自己下载github里的文件，找地方放，然后替换链接

local_files_only是让取本地缓存，这个缓存在当前用户文件夹下

ubuntu

/home/fxbox/.cache/huggingface/hub

mac

/Users/linzhiji/.cache/huggingface/hub

把能翻墙的机器里的缓存，拷贝到不能翻墙的机器里
