[TensorFlow学习手记] 2

## sess Session 会话控制的简单运用## sess 每run一次，便执行一次结构## sess.close() import tensorflow as tfmatrix1 = tf.constant([[3,3]])  # 1*3 矩阵matrix2 = tf.constant([[2],                       [2]])  # 2*1 矩阵product = tf.matmul(matrix1,matrix2)  # matrix multiply np.dot(m1,m2)### method 1 sess = tf.Session()result = sess.run(product)print(result)sess.close()### method 2with tf.Session() as sess:    result2 = sess.run(product)    print(result2)# 已经自动close
