根据log提示，修改C:\sd-webui-aki\sd-webui-aki-v4.1\extensions\deforum-for-automatic1111-webui\scripts\deforum_helpers目录下的general_utils.py文件最后的download_file_with_checksum(url, expected_checksum, dest_folder, dest_filename)方法，添加replace替换操作。

1. def download_file_with_checksum(url, expected_checksum, dest_folder, dest_filename):
2.     dest_folder=dest_folder.replace("\", "/")
3.     expected_full_path = os.path.join(dest_folder, dest_filename)
4.     expected_full_path=expected_full_path.replace("\", "/")
5.     if not os.path.exists(expected_full_path) and not os.path.isdir(expected_full_path):
6.         load_file_from_url(url=url, model_dir=dest_folder, file_name=dest_filename, progress=True)
7.         if checksum(expected_full_path) != expected_checksum:
8.             raise Exception(f"Error while downloading {dest_filename}.]nPlease manually download from: {url}\nAnd place it in: {dest_folder}")

复制代码

然后重新运行sd-webui，若报错

1. Loading MiDaS model from dpt_large-midas-2f21e586.pt...
2. Error verifying pickled file from C:\sd-webui-aki\sd-webui-aki-v4.1\models/Deforum\dpt_large-midas-2f21e586.pt:
3. Traceback (most recent call last):
4.   File "C:\sd-webui-aki\sd-webui-aki-v4.1\modules\safe.py", line 82, in check_pt
5.     with zipfile.ZipFile(filename) as z:
6.   File "C:\sd-webui-aki\sd-webui-aki-v4.1\python\lib\zipfile.py", line 1269, in __init__
7.     self._RealGetContents()
8.   File "C:\sd-webui-aki\sd-webui-aki-v4.1\python\lib\zipfile.py", line 1336, in _RealGetContents
9.     raise BadZipFile("File is not a zip file")
10. zipfile.BadZipFile: File is not a zip file

复制代码

则删除Deforum插件，并且删除本地目录 C:\sd-webui-aki\sd-webui-aki-v4.1\models/Deforum\下的dpt_large-midas-2f21e586.pt文件。重新安装Deforum插件，并运行，会重新下载该文件。
最后重新运行即可。
