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。

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

然后重新运行sd-webui，若报错

    raise BadZipFile("File is not a zip file")

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。
