Print output of a Theano network

Question

I am sorry, very newbee question... I trained a neural network with Theano and now I want to see what it outputs for a certain input.

So I can say:

test_pred = lasagne.layers.get_output(output_layer, dataset['X_test'])

where output_layer is my network. Now, the last layer happens to be a softmax, so if I say:

print "%s" % test_pred

I get

Softmax.0

I see why I get this I think (namely, because the output is a symbolic tensor variable), but I don't see how I can see the actual values.

And just so you know, I did read this post and also the documentation on printing and FAQ, which I am also not fully grasping, I am afraid...

Answer 1

1. Use .eval() to evaluate the symbolic expression
2. Use Test Values
