I am practicing the keras method called concatenate.
And use of with statement in this example kind of got me thinking the purpose of this statement
The example code looks like:
import numpy as np
import keras.backend as K
import tensorflow as tf
t1 = K.variable(np.array([ [[1, 2], [2, 3]], [[4, 4], [5, 3]]]))
t2 = K.variable(np.array([[[7, 4], [8, 4]], [[2, 10], [15, 11]]]))
d0 = K.concatenate([t1 , t2] , axis=-2)
init = tf.global_variables_initializer()
with tf.Session() as sess:
sess.run(init)
print(sess.run(d0))
Then I check document from: tensorflow and says that:
A session may own resources, such as tf.Variable, tf.QueueBase, and tf.ReaderBase. It is important to release these resources when they are no longer required. To do this, either invoke the tf.Session.close method on the session, or use the session as a context manager.
Which I believe has already explained all of it,but can somebody give me more intuitive explanation.
Thanks in advance and have a nice day!
