Is there any method in tensorflow like get_output in lasagne
I found that it is easy to use lasagne to make a graph like this.
import lasagne.layers as L
class A:
def __init__(self):
self.x = L.InputLayer(shape=(None, 3), name='x')
self.y = x + 1
def get_y_sym(self, x_var, **kwargs):
y = L.get_output(self.y, {self.x: x_var}, **kwargs)
return y
through the method get_y_sym, we could get a tensor not a value, then I could use this tensor as the input of another graph.
But if I use tensorflow, how could I implement this?

I'm not familiar with lasagne but you should know that ALL of TensorFlow uses graph based computation (unless you use tf.Eager, but that's another story). So by default something like:
net = tf.nn.conv2d(...)
returns a reference to a Tensor object. In other words, net is NOT a value, it is a reference to the output of the convolution node created by tf.nn.conv2d(...).
These can then be chained:
net2 = tf.nn.conv2d(net, ...) and so on.
To get "values" one has to open a tf.Session:
with tf.Session() as sess:
net2_eval = sess.run(net2)
