T.shape is expecting a tensor, not a layer object.

Hello,
In the above code, I want the predicted value at the output layer. Thus,
I am trying to get it using T.sahpe(network).eval and T.eval(prediction)
But using these command I am getting following errors and unable to
locate it. Please help to configure this error.
T.shape(network).eval()
