pool_2d() got an unexpected keyword argument 'ws'

#The following github code is not consistent with keras 2.0.0. I ran cifar10_cnn.py from examples. It is giving error in calling pool_2d(). Function arguments do not seem to be consistent.

Kindly check this.

Updating to the latest version of Theano via

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

worked for me.

In theano 0.8, I believe the argument is ds. It seems that the code is intended for theano 0.9.
