Graphlab get_dependencies() SSL certificate verify failed

I am having some problems to get graphlab to work. Every time I want to import graphlab I get the message:

ACTION REQUIRED: Dependencies libstdc++-6.dll and libgcc_s_seh-1.dll not found.

1. Ensure user account has write permission to C:\Users\Lorenzpc\Desktop\cousera\anaconda installation\Anaconda2\envs\gl-env\lib\site-packages\graphlab
2. Run graphlab.get_dependencies() to download and install them.
3. Restart Python and import graphlab again.

By running the above function, you agree to the following licenses.

* libstdc++: https://gcc.gnu.org/onlinedocs/libstdc++/manual/license.html
* xz: http://git.tukaani.org/?p=xz.git;a=blob;f=COPYING

After this message I do: graphlab.get_dependencies() and get the following message:

Downloading xz.

IOError: [Errno socket error] [SSL: CERTIFICATE_VERIFY_FAILED] certificate verify failed (_ssl.c:590)

I have searched here before, but none of the problems were the same or the suggested solutions didn't work. I have tried to reinstall anconda and graphlab several times in different place (I thought maybe it had something to do with the write permissions) both with the installer an manually using pip. I have tried to manually extract the files (a solution suggested here: Graphlab Create setup error: graphlab.get_dependencies() results in BadZipFile error). I also tried to change the line of code that causes the fault in dependencies.py so it would just look for the files on my PC (suggestion from an other forum). But no matter what I do I can't get it to work.

From what I understand, it looks like the error is caused by a failed connection or because it was unable to set up an SSL connection. But I am not using a proxy and have no firewall enabled.

Any suggestions to the cause/solution to this problem would be greatly appreciated, I have been hurting my head over this for a while.

I encountered a very similar SSL-related error. "Monkey-patching" the ssl module, as suggested in https://github.com/mtschirs/quizduellapi/issues/2, solved that problem. Please try executing the following statements before executing graphlab.get_dependencies():

import ssl
if hasattr(ssl, '_create_unverified_context'):
    ssl._create_default_https_context = ssl._create_unverified_context

Hope this unblocks your graphlab set-up.
