Python的SSL认证问题

我试图下载这是在所谓处理的数据MNIST：

tensorflow.examples.tutorials.mnist.input_data.read_data_sets（）

至于我m知道read_data_sets向服务器发送拉取请求以下载（大约）1.5GB数据。

我不断收到此错误回溯：

File "/Library/Frameworks/Python.framework/Versions/3.6/lib/python3.6/urllib/request.py", line 1318, in do_open encode_chunked=req.has_header('Transfer-encoding')) File "/Library/Frameworks/Python.framework/Versions/3.6/lib/python3.6/http/client.py", line 1239, in request self._send_request(method, url, body, headers, encode_chunked) File "/Library/Frameworks/Python.framework/Versions/3.6/lib/python3.6/http/client.py", line 1285, in _send_request self.endheaders(body, encode_chunked=encode_chunked) File "/Library/Frameworks/Python.framework/Versions/3.6/lib/python3.6/http/client.py", line 1234, in endheaders self._send_output(message_body, encode_chunked=encode_chunked) File "/Library/Frameworks/Python.framework/Versions/3.6/lib/python3.6/http/client.py", line 1026, in _send_output self.send(msg) File "/Library/Frameworks/Python.framework/Versions/3.6/lib/python3.6/http/client.py", line 964, in send self.connect() File "/Library/Frameworks/Python.framework/Versions/3.6/lib/python3.6/http/client.py", line 1400, in connect server_hostname=server_hostname) File "/Library/Frameworks/Python.framework/Versions/3.6/lib/python3.6/ssl.py", line 401, in wrap_socket _context=self, _session=session) File "/Library/Frameworks/Python.framework/Versions/3.6/lib/python3.6/ssl.py", line 808, in init self.do_handshake() File "/Library/Frameworks/Python.framework/Versions/3.6/lib/python3.6/ssl.py", line 1061, in do_handshake self._sslobj.do_handshake() File "/Library/Frameworks/Python.framework/Versions/3.6/lib/python3.6/ssl.py", line 683, in do_handshake self._sslobj.do_handshake() ssl.SSLError: [SSL: CERTIFICATE_VERIFY_FAILED] certificate verify failed (_ssl.c:748)

它显然有事情做与SSL证书Python使用......让我去/应用/ Python的3.6 /并执行“安装Certifactions。命令“位于那里，并得到这个错误：

Traceback (most recent call last): File "/Library/Frameworks/Python.framework/Versions/3.6/lib/python3.6/shutil.py", line 544, in move os.rename(src, real_dst) PermissionError: [Errno 13] Permission denied: '/Library/Frameworks/Python.framework/Versions/3.6/lib/python3.6/site-packages/certifi-2015.04.28.dist-info/DESCRIPTION.rst' -> '/var/folders/mq/g_jy_1qx1vjdb3xmdh7y62y80000gn/T/pip-3m8ixnf5-uninstall/Library/Frameworks/Python.framework/Versions/3.6/lib/python3.6/site-packages/certifi-2015.04.28.dist-info/DESCRIPTION.rst'

During handling of the above exception, another exception occurred:

是否有我的文件系统权限有问题吗？我确实在一个月前在这台电脑上重新安装了OSX ...

有没有一种方法可以手动安装证书？或者发出拉请求将数据下载到非https地址？

Answer 1

以http替换HTTPS得到它运行

在了contrib /学习/蟒蛇/学习/集/ mnist.py 编辑符合 SOURCE_URL = 'http://storage.googleapis.com/cvdf-datasets/mnist/'
