How do I install Theano and Lasagne in Anaconda (Jupyter)?

I have been trying to install Lasagne and Theano in Anaconda (Jupyter) on MacOS Sierra (10.12.3) to use this neural network: neural-storyteller

However when I try to import them in Jupyter:

import lasagne
import theano

I get this error:

ImportError                               Traceback (most recent call last)
<ipython-input-2-7d877a974cd7> in <module>()
----> 1 import lasagne
      2 import theano

//anaconda/lib/python2.7/site-packages/lasagne/__init__.py in <module>()
     11 section 'Install from PyPI' in the installation docs for more details:
     12 http://lasagne.readthedocs.org/en/latest/user/installation.html#install-from-pypi
---> 13 """)
     14 else:
     15     del theano

ImportError: Could not import Theano.

Please make sure you install a recent enough version of Theano.  See
section 'Install from PyPI' in the installation docs for more details:
http://lasagne.readthedocs.org/en/latest/user/installation.html#install-from-pypi

My guess is that I installed Theano on a different version of python because when I make a normal python file (.py) and import lasagne and theano they work. Also, when I look in the anaconda folder in the User directory there is no theano folder but there is one in the miniconda2 folder (/Users/Pit/miniconda2/pkgs/theano-0.9.0-py27_0). I could just use a .py file, but I also need the caffe library which I could only get to work with Anaconda python.

Does anybody know how to install the right version of theano that works in Anaconda (Jupyter)? Any help would be much appreciated

I had faced the same issue. I think it's because Theano installation was not proper. So here is what I did and it started working after that :

In Anaconda Prompt

conda install theano

Follow through the installation. It would probably ask for some confirmations. Then,

pip install -r https://raw.githubusercontent.com/Lasagne/Lasagne/master/requirements.txt

After that,

pip install https://github.com/Lasagne/Lasagne/archive/master.zip

I think that should do the trick. It started working after that in my case. Restart the kernel once. For more context : https://pypi.org/project/Lasagne/

You should check which jupyter and which python is being called by using the command: 

which python

If you do:

which jupyter

they should be in the same directory. For example: 

$:/home/spark : which jupyter
~/anaconda2/bin/jupyter
$:/home/spark : which python
~/anaconda2/bin/python

If they're not the same, then that could explain why you cannot import some libraries (because they're installed under a different python instance).

Unless you need both, I would remove either anaconda or miniconda to make things simpler and less confusing.

Theano works fine with Anaconda and in Jupyter in my experience.
