You are right, requiring developer mode was a bad experience. This was fixed in huggingfacehub v0.10: the download code now checks whether symlinks are supported, and when they are not, like on Windows without developer mode or admin rights, it falls back to copying the files instead of failing. So just upgrade huggingfacehub and the downloads will work for regular users with no special settings. Source: https://github.com/huggingface/huggingface_hub/issues/1062
