Your traceback got cut prematurely, but I think that your problem is that you didn’t conda install libpython. You should follow these instructions to install theano on windows. I recommend you uninstall everything and start again from scratch, to avoid conflicting packages.
Another thing, pymc3 no longer supports python2. The last version that supported py2 was 3.6 (the current release) but we will release 3.7 very soon, with many fixes and new features, and you won’t be able to use it in Python 2.
