Tensorflow中的Python SSL认证问题
Tensorflow中的Python SSL认证问题
提问于 2017-10-20 23:34:36
我正在尝试下载MNIST数据，这些数据应该是在以下文件中处理的：
tensorflow.examples.tutorials.mnist.input_data.read_data_sets()
据我所知，read_data_sets向服务器发送拉请求，以下载1.5GB的数据。
我一直收到这个跟踪错误：
File

self._sslobj.do_handshake() ssl.SSLError: [SSL: CERTIFICATE_VERIFY_FAILED] certificate verify failed (_ssl.c:748)这显然与SSL cert python的使用有关..。因此，我转到/Applications/Python3.6/，执行了位于那里的“InstallyCertifactions.command”，得到了以下错误：

During handling of the above exception, another exception occurred:

有办法手动安装证书吗？还是发出拉请求将数据下载到非https地址？
