downloading Olivetti faces from urllib.error.HTTPError: HTTP Error 403: Forbidden

最近在学Tensorflow和Sklearn，一个原因是想搞机器视觉，另外一个原因是想探索深入了解一下AI等等方面的知识，例如神经网络等等。

遇到的第一个问题是有些包用不了，一个可能是因为墙墙，另外一个可能是因为历史版本太久没更新导致网页地址挂了。代码是1.ipynb，具体报错如下：

#1.ipynb
from sklearn.datasets import fetch_olivetti_faces

# 从当前目录下加载人脸数据集，若没有则联网下载到当前目录下
faces = fetch_olivetti_faces(data_home='./')

downloading Olivetti faces from https://ndownloader.figshare.com/files/5976027 to ./

    response = self.parent.error(

    return self._call_chain(*args)

    raise HTTPError(req.full_url, code, msg, hdrs, fp)
urllib.error.HTTPError: HTTP Error 403: Forbidden

解决办法也简单。

只需将原数据集olivetti_py3.pkz放到当前目录下：

原链接挂了，这里放一个网盘
