ValueError:两个结构没有相同数量的元素 [英] ValueError: The two structures don't have the same number of elements
本文介绍了ValueError:两个结构没有相同数量的元素的处理方法,对大家解决问题具有一定的参考价值,需要的朋友们下面随着小编来一起学习吧!
问题描述
with tf.variable_scope('forward'):
cell_img_fwd = tf.nn.rnn_cell.GRUCell(hidden_state_size, hidden_state_size)
img_init_state_fwd = rnn_img_mapped[:, 0, :]
img_init_state_fwd = tf.multiply(
img_init_state_fwd,
tf.zeros([batch_size, hidden_state_size]))
rnn_outputs2, final_state2 = tf.nn.dynamic_rnn(
cell_img_fwd,
rnn_img_mapped,
initial_state=img_init_state_fwd,
dtype=tf.float32)
这是我输入100x196x50尺寸的GRU的代码,应沿第二个尺寸(即196)解压缩. hidden_state_size
是50,batch_size
是100.但是我得到以下错误:
This is my code for a GRU for input of dimension 100x196x50, it should be unpacked along the second dimension (that is 196). hidden_state_size
is 50, batch_size
is 100. However I get the following error:
ValueError: The two structures don't have the same number of elements.
First structure: Tensor("backward/Tile:0", shape=(100, 50), dtype=float32),
second structure:
(<tf.Tensor 'backward/bwd_states/while/GRUCell/add:0' shape=(100, 50) dtype=float32>,
<tf.Tensor 'backward/bwd_states/while/GRUCell/add:0' shape=(100, 50) dtype=float32>).
有什么线索可以解决这个问题吗?
Any clue how to resolve this?
推荐答案
你好,我遇到了同样的问题,我尝试这样做:
Hello I had the same problem, I tried to do this:
highest = tf.map_fn(lambda x : (-x, x), indices)
这给了我类似的错误消息:
This gave me a similar error message:
ValueError: The two structures don't have the same number of elements.
First structure (1 elements): <dtype: 'int32'>
Second structure (2 elements): (<tf.Tensor 'map/while/Neg:0' shape=() dtype=int32>, <tf.Tensor 'map/while/TensorArrayReadV3:0' shape=() dtype=int32>)
我通过使dtypes显式解决了这个问题:
I resolved this by making the dtypes explicit:
highest = tf.map_fn(lambda x : (-x, x), indices, dtype=(tf.int32, tf.int32))
