Question

在简单的程序中，我无法完成一项简单的任务并得到以下错误。

import tensorflow as tf

x_1= tf.constant([1, 2, 3])
x_1= tf.reshape(x_1, shape= (1, 3))
x_2= tf.constant([2, 3, 4])
x_2= tf.reshape(x_2, shape= (1, 3))
x_3= tf.constant([3, 4, 5])
x_3= tf.reshape(x_3, shape= (1, 3))
x= tf.concat((x_1, x_2, x_3), axis=0)

for i in range(0, 3):
    x[i, :]= x[i, :]+ 1

init= tf.global_variables_initializer()

with tf.Session() as sess:
   y= sess.run(x)

我收到以下错误：

TypeError：'Tensor'对象不支持项目分配

Answer 1

索引无法访问/修改Tensor对象。

以下是修正的代码：

import tensorflow as tf

x_1 = tf.constant([1, 2, 3])
x_1 = tf.reshape(x_1, shape=(1, 3))
x_2 = tf.constant([2, 3, 4])
x_2 = tf.reshape(x_2, shape=(1, 3))
x_3 = tf.constant([3, 4, 5])
x_3 = tf.reshape(x_3, shape=(1, 3))
x = tf.concat((x_1, x_2, x_3), axis=0)

x = tf.add(x, tf.constant(1, shape=x.shape))

with tf.Session() as sess:
    sess.run(tf.global_variables_initializer())
    y = sess.run(x)
    print(y)

对象不支持张量流中的项目赋值
