问题描述
我正在尝试下载据称在以下位置处理的 MNIST 数据:
I'm trying to download the MNIST data which is supposedly handled in:
tensorflow.examples.tutorials.mnist.input_data.read_data_sets()
tensorflow.examples.tutorials.mnist.input_data.read_data_sets()
据我所知 read_data_sets 向服务器发送拉取请求以下载(大约)1.5GB 的数据.
As far as I'm aware read_data_sets sends a pull request to a server to download the (approx.) 1.5GB of data.
我不断收到此回溯错误:
I keep getting this traceback error:

这显然与 python 使用的 SSL 证书有关...所以我转到/Applications/Python 3.6/并执行位于那里的Install Certifactions.command"并收到此错误:
It obviously has something to do with the SSL cert python uses... so I went to /Applications/Python 3.6/ and executed the "Install Certifactions.command" located there and got this error:

在处理上述异常的过程中，又发生了一个异常:
During handling of the above exception, another exception occurred:

我的文件系统权限有问题吗?大约一个月前，我真的在这台计算机上重新安装了 OSX...
Is there something wrong with my filesystem permissions? I quite literally reinstalled OSX about a month ago on this computer...
有没有办法手动安装证书?或者发出 pull request 将数据下载到非 https 地址?
Is there a way I can manually install the certs? Or issue the pull request to download the data to a non-https address?
推荐答案
安装证书，或者双击 /Applications/Python 3.6/Install Certificates.command 中的文件(在 macOS 上)，或者从 bash 终端运行此命令:
Install certificates, either double-clicking the file in /Applications/Python 3.6/Install Certificates.command (on macOS), or running this command from a bash terminal:
/Applications/Python\ 3.6/Install\ Certificates.command
现在安装了证书以通过 HTTPS 下载数据.
And now the certificates are installed to download the data over HTTPS.
