TensorFlow : Perintah Yang Sering Digunakan

Berikut adalah perintah yang sering dipakai ketika menggunakan library TensorFlow.

import tensorflow as tf

hello = tf.constant('Hello ')
world = tf.constant('World')

with tf.Session() as sess:
    result = sess.run(hello+world)
    
print(result)

#b'Hello World'



const = tf.constant(10)
matrix = tf.fill((4,4), 10)
myzeros = tf.zeros((4,4))
myones = tf.ones((4,4))
myrandn = tf.random_normal((4,4), mean=0, stddev=1)
myrandu = tf.random_uniform((4,4), minval=0, maxval=1)

myops = [const, matrix, myzeros, myones, myrandn, myrandu]

with tf.Session() as sess:
    for op in myops:
        print(sess.run(op), '\n')
