由于tf.concat接口更改，来自tensorlayer ConcatLayer的TypeError

Question

我使用tensorlayer的concatLayer来连接两个输入，一个是嵌入，另一个是其他额外的输入。tl.layers.ConcatLayer总是运行到TypeError中："Expected int32，got包含'_Message‘类型的张量。“

似乎tf.concat() api的变化可能是一个原因，但我使用的是tf 1.2.0 + tensorlayer 1.5.1 (python 2.7.13 | Anaconda 4.3.0)

有人能帮上忙吗？谢谢-Wei

网络设计：

emb_net = tl.layers.EmbeddingInputlayer(
    inputs = x,
    vocabulary_size = VOCAB_SIZE,
    embedding_size = FLAGS.embedding_size,
    E_init = tf.random_uniform_initializer(
         -FLAGS.init_scale, FLAGS.init_scale),
    name = 'embedding')

word_bound = tl.layers.InputLayer(
    inputs = x_wb,
    name = 'word_boundary')

network = tl.layers.ConcatLayer(
    layer = [emb_net, word_bound],
    concat_dim = 1,
    name = 'concat_layer')

Answer 1

我解决了这个问题，尽管还有点迷惑。

在文件anaconda2/lib/python2.7/site-packages/tensorlayer/layers.py，的4717行中，只需保留tf.concat()的第一行

try: # TF1.0
    self.outputs = tf.concat(self.inputs, concat_dim, name=name)
except: # TF0.12
    self.outputs = tf.concat(concat_dim, self.inputs, name=name)

你能检查一下x和x_wb的尺寸吗？
