python学习日记7tensorflow-矩阵运算

写了测试小程序

import tensorflow as tf
sess =tf.Session()
a=tf.ones([2,3],tf.int32)
print(sess.run(a))
b=tf.zeros([2,3],tf.int32)
print(sess.run(b))
c=tf.reshape([1,2,3,4,5,6],[3,2])
print(sess.run©)
d=tf.matmul(c,a)
print(sess.run(d))
e=tf.matmul(a,c)
print(‘matmul:’,sess.run(e))
f=tf.reshape([1,2,3,4],[4,-1])
print(‘reshape:’,sess.run(f))
g=tf.add(a,tf.transpose©)
print(‘add:’,sess.run(g))
h=tf.multiply(a,tf.transpose©)
print(‘multiply:’,sess.run(h))
