So i finally managed to get theano up and running on the GPU using this guide. (the test code runs fine, telling me it used the GPU, YAY!!) I then wanted to try it out and followed this guide for training a CNN on digit recognition.
problem is: i get errors from the way lasagne calls theano (i guess there is a version mismatch here):
Using gpu device 0: GeForce GT 730M (CNMeM is disabled, cuDNN not available)
Traceback (most recent call last):

From reading about the error message, it seems that 'downsample' was changed, so why is my lasagne still calling it??
trying to update my lasagne version gives:
C:\WINDOWS\system32>pip3.5 install Lasagne==0.1
Collecting Lasagne==0.1
Requirement already satisfied: numpy in c:\users\soren jensen\anaconda3\lib\site-packages (from Lasagne==0.1)
and running the code sample
import theano
import os
print(theano.config.compiledir)
print("Theano version %s" % theano.__version__)
theano_dir = os.path.dirname(theano.__file__)
print("theano is installed in %s" % theano_dir)
reveals that python3.5 uses theano v 0.9

Sorry for the long post, but i'm going a little crazy of this not working.. Maybe i am wrong in the version mismatch and the error is something else?
