python - 不可散列类型 : 'list' in printing Tensorflow vector

Question

我正在打印 Tensorflow 的矢量和矩阵。它打印 scalar 但显示 vector、Matrix 和 Tensor

的错误

代码如下:

import tensorflow as tf    
scalar = tf.constant([2])
vector = tf.constant([3,4,5])
Matrix = tf.constant([1,2,3],[4,5,6],[7,8,9])
Tensor = tf.constant([ [[1,2,3],[4,5,6],[7,8,9]],
                       [[1,2,3],[4,5,6],[7,8,9]],
                       [[1,2,3],[4,5,6],[7,8,9]] ])
with tf.Session() as session:
    result = session.run(scalar)
    print (result)
    result = session.run(vector)
    print (result)
    result = session.run(Matrix)
    print (result)
    result = session.run(Tensor)
    print (result)

我收到以下错误:

TypeError: unhashable type: 'list'

我该如何解决？

Answer 1

您的第 4 个陈述有误:使用

Matrix = tf.constant([ [1,2,3],[4,5,6],[7,8,9] ])
#                    ^ extra parenthesis here

代替

Matrix = tf.constant([1,2,3],[4,5,6],[7,8,9])
