Installing Theano with Canopy EPD on windows 7, 64 bit

Question

I have successfully installed theano on Canopy EPD, windows 7, 64 bit. While importing theano (for testing at first time), I am getting this error. Can anybody help. Thanks.

It is similar to this question: Installing Theano on EPD (Windows x64)

Answer 1

Since this question wasnt properly closed by the author and it's also relevant to most EPD users, including me when i first started with EPD + theano, i will answer to it.

First, remove any other python environment if possible. Be sure there is no other conflicting environment path of python, just in case.

1.Install EPD CANOPY

2.Install the MinGW package that is on package installer available on Canopy application

That should be easy to do, you just open the package manager from inside the Canopy application.

3.Install Theano from inside EPD

Before you go spamming

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

in every prompt of command you see, DONT DO IT.

-- Instead, Open Canopy.

In Canopy screen, go to "Tools", and then open "Canopy Command Prompt"

A screen exactly like the CMD from windows will open.

On that screen, execute :

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

Should work fine now.

--

However, dont forget you will need , obviously the Windows SDK , depending on the windows version of course. You can try installing the last Visual Studio with comes with everything you need.
