Theano has changed its API for the 0.9.0 version. lasagne haven't updated yet.

max_pool_2D method doesn't exist anymore in ``downsample".

I found the solution for this issue in Theano/Theano#4337

I use Theano-0.9.0rc1 with Lasagne-0.2.dev1.

And I don't get that error. Do you have those versions installed?

Theano on my machine is 0.9.0rc2

The documentation indicates this API change:

I removed the maxpool layer in the training. however, we need to re-train the model
