我正在使用Keras并尝试加载mnist数据集。

该网站的链接是：https ://s3.amazonaws.com/img-datasets/mnist.pkl.gz

它在浏览器中工作。但是当我调用“mnist.load_data()”时，我得到了异常：

ssl.SSLEOFError: EOF occurred in violation of protocol (_ssl.c:645)

已经提供了许多解决方案，我几乎尝试了所有解决方案。

下面是堆栈跟踪：

我在控制台上的“openssl 版本”：

openssl version
OpenSSL 1.0.2e 3 Dec 2015

在 python 控制台中：

>>> import OpenSSL
>>> OpenSSL.__version__
'0.15.1'
>>> import ssl 
>>> print (ssl.OPENSSL_VERSION)
OpenSSL 1.0.2e 3 Dec 2015

我正在使用 anaconda 附带的 Python 3.5

我还使用升级了 OpenSSL，conda install OpenSSL 但错误仍然存​​在。

我还尝试了一个补丁：

import ssl
from functools import wraps
def sslwrap(func):
    @wraps(func)
    def bar(*args, **kw):
        kw['ssl_version'] = ssl.PROTOCOL_TLSv1
        return func(*args, **kw)
    return bar

ssl.wrap_socket = sslwrap(ssl.wrap_socket)

但仍然没有解决办法。我怎样才能摆脱这个错误？
