TensorFlow 2.0第一个Demo：Hello World

tensor安装成功

开始试用第一个测试例子：Hello World

import tensorflow as tf
tf.executing_eagerly()
A = tf.constant([[1, 2], [3, 4]])
B = tf.constant([[5, 6], [7, 8]])
C = tf.matmul(A, B)
print(C)
tf.print('This is my first tensorFlow example: Hello World! Congratulations!!!')

输出为：

tf.Tensor(
[[19 22]
 [43 50]], shape=(2, 2), dtype=int32)
This is my first tensorFlow example: Hello World! Congratulations!!!

成功！
