I am trying to test theano with GPU (AMD graphics card).
I have installed latest versions of theano and libgpuarray.
However, I get the following error when trying to execute test script 
from: http://deeplearning.net/software/theano/tutorial/using_gpu.html

THEANO_FLAGS=mode=FAST_RUN,device=opencl0:0,floatX=float32 python check1.py
