【StableDiffusion秋叶包反斜杠问题】Failed to find xxx\sd-webui-aki-v4.8\...\xxx.pth_sd秋叶4.8

一、问题发生

1.在我额外安装预处理器时报错

意思是没办法找到有这么一个包（但我已经把这个包扔进去了）

完整报错：

2.问题原因

看看这里，为什么反斜杠突然变成了 “/” ？
这种路径能找到才怪了

二、解决办法

1.寻找报错位置

抛出异常：
能看到是在这个 hf_hub_download 函数中抛出的异常。

File "S:\app_AI\stableDiffusion-webui-aki\sd-webui-aki-v4.8\python\lib\site-packages\huggingface_hub\file_download.py", line 1291, in hf_hub_download
    raise LocalEntryNotFoundError(
1
2

继续寻找：
可以看到这个函数 _inner_fn，它很有可能是一个 inner_wrapper

File "S:\app_AI\stableDiffusion-webui-aki\sd-webui-aki-v4.8\python\lib\site-packages\huggingface_hub\utils\_validators.py", line 120, in _inner_fn
    return fn(*args, **kwargs)

继续寻找：
果然，我们看到了一个 增强函数 “hf_hub_download_wrapper_inner”

File "<enhanced_experience patches.hfmirror.huggingface_hub>", line 52, in hf_hub_download_wrapper_inner
1

继续寻找：
我们发现了要寻找的包含 “路径”参数 的第一个函数 hf_hub_download
接下来直奔这个文件，寻找此函数，能够清晰看到它使用了 “ / ” 作为 split 分隔

File "S:\app_AI\stableDiffusion-webui-aki\sd-webui-aki-v4.8\python\lib\site-packages\hand_refiner\util.py", line 178, in custom_hf_download
  model_path = hf_hub_download(repo_id=pretrained_model_or_path,

2.开始解决

更改 “ / ” 为 “ \\”，即可解决问题（转义字符，必须来两个 \ ，不用我说了吧）
如图所示：
