Import theano gives the AttributeError: module 'theano' has no attribute 'gof'

Question

I have python 3. I installed \"Theano\" bleeding edge and \"Keras\" using

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

Answer 1

I used conda to install theano and still got the same error. After much trial and error and StackOverflow searches, what worked for me was to first run:

conda install m2w64-toolchain

followed by:

conda install theano

Alternatively you can chain the modules together when you create an environment, for example:

conda create -n myenv python=3.5 m2w64-toolchain theano

Also important to follow @gtnbz2nyt's advice and restart your Python instance.
