title: Package installed by Conda, Python cannot find it
body: <p>I try to install Theano by Anaconda. It works, but when I enter the python -i,  <code>import theano</code> shows <code>No module named 'theano'</code>. Do I need to switch another interpreter of Python, how? Also, for the packages installed by conda, if I don't double install them, can I find in Python? How is Python related to Python by Anaconda? Thanks!!!</p>
