Installing Theano on EPD (Windows x64)

I'm trying to install Theano on Enthought Python Distribution (EPD), but I am getting a weird error. Here is what my installation looks like:

I have installed EPD to C:\Python27.
After that, I have installed pip by using easy_install pip
I installed Theano by using pip install Theano

To test, I start ipython and type import theano. I get the following error:

Problem occurred during compilation with the command line below:

Does anyone know how to get Theano to run with EPD?

Solution

The last release of Theano(0.5) has some problem on Windows. You need to install the bleeding edge version. You can update your version like this:

pip install --upgrade --no-deps git+git://github.com/Theano/Theano.git

This should solve the problem. If not, you probably have some conflict with a different installation of gcc. Do you have installed it with cygwin or mingw? EPD installs its own version of mingw.
