Theano import error: No module named cPickle
Solution 1
I had the same problem and upgrading six solved issue:
sudo easy_install --upgrade six
Solution 2
Try to avoid using sudo
at all costs. Open a python session and run
import six
print six.__version__
print six.__file__
The version will likely not be most recent (1.10.0), so go manually delete the six.py and six.pyc files at the imported path, and then run pip install six
. Python should now be importing the latest version of six, compatible with Theano :)

I'm pretty sure there is no problem with cPickle. Can it be the problem of other dependencies? It's true that I upgraded all the packages this morning, so that a conflict of version may occur. Nonetheless, the problem still exists after I switched to the bleeding-edge version of theano. Would someone help me figure it out?
PS: My developing device is Macbook Pro 13(early 2015); my system version is OS X 10.10.5; python version is 2.7.10
=========================== Second Edit ===================================
It seems I do have latest version of six installed on my Mac.
