I'm learning tensorflow right now and I have made a habit in programming of printing my variables to see what I'm working with as I'm coding. I can't figure out how to print the values of constant and Variable objects in tensorflow
How can I get back the values that I assigned to the instances?
import tensorflow as tf
C_int = tf.constant(134)
#Tensor("Const_11:0", shape=TensorShape([]), dtype=int32)
V_mat = tf.Variable(tf.zeros([2,3]))
#<tensorflow.python.ops.variables.Variable object at 0x10672fa10>
C_str = tf.constant("ABC")
#Tensor("Const_16:0", shape=TensorShape([]), dtype=string)
C_int
#134
V_mat
#array([[ 0., 0., 0.],
# [ 0., 0., 0.]])
C_str
#ABC
The simplest way to see the values of your tensors is to create a tf.Session and use Session.run to evaluate the tensors. Thus, your code would look like:
import tensorflow as tf
C_int = tf.constant(134)
V_mat = tf.Variable(tf.zeros([2,3]))
C_str = tf.constant("ABC")
sess = tf.Session()
sess.run(C_int)
#134
sess.run(V_mat)
#array([[ 0., 0., 0.],
# [ 0., 0., 0.]])
sess.run(C_str)
#ABC
sess.close()
