[theano-users] raise ImportError() on calling import theano

[Kamil Szynkarczuk]

Hi all,

I'm having trouble getting started with Theano. Would someone be able to
help me with what I'm doing incorrectly?

Description of my problem

When I install and try to import theano, I get an error. I've tried
installing using conda, pip/pypi, and the bleeding edge installation using
pip/git. My numpy and scipy version may be too new as I'm using
1.14.0rc1+mkl and 1.0.0 respectively, but was unable to downgrade to the
required versions as scipy failed to compile as it requires numpy+mkl, and
a version as old as required by theano is no longer available here
https://www.lfd.uci.edu/~gohlke/pythonlibs/.

*Here is the code snippet that generates the error:*
`import theano`

*I installed the bleeding edge version using*
'C:\Downloads>pip install
git+https://github.com/Theano/Theano.git#egg=Theano'


Console output and traceback

Was a dupe of https://github.com/Theano/Theano/issues/6532

I also blew up my anaconda env, which didn't help!
