'Python SSL Certification Problems in Tensorflow

I'm trying to download the MNIST data which is supposedly handled in:

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

As far as I'm aware read_data_sets sends a pull request to a server to download the (approx.) 1.5GB of data.

I keep getting this traceback error:

File

line 683, in do_handshake
    self._sslobj.do_handshake() ssl.SSLError: [SSL: CERTIFICATE_VERIFY_FAILED] certificate verify failed (_ssl.c:748)

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:

"/Library/Frameworks/Python.framework/Versions/3.6/lib/python3.6/shutil.py",

During handling of the above exception, another exception occurred:

Is there something wrong with my filesystem permissions? I quite literally reinstalled OSX about a month ago on this computer...

Is there a way I can manually install the certs? Or issue the pull request to download the data to a non-https address?

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

And now the certificates are installed to download the data over HTTPS.

replacing https with http got it running

In contrib/learn/python/learn/datasets/mnist.py edit the line with SOURCE_URL='http://storage.googleapis.com/cvdf-datasets/mnist/'
