AttributeError:模块'tensorflow.contrib.seq2seq“”没有属性“DynamicAttentionWrapperState”

Question

我在使用tensorflow 1.11.0时收到了这个错误消息

Answer 1

弃用问题，请改用tf.contrib.seq2seq.AttentionWrapper。我猜你从https://github.com/thunlp/TensorFlow-Summarization/blob/master/src/bigru_model.py借了一些代码。在

attention = tf.contrib.seq2seq.BahdanauAttention(num_units = size_layer, memory = encoder_out, memory_sequence_length = seq_len))

decoder_cell = tf.contrib.seq2seq.AttentionWrapper(cell = tf.nn.rnn_cell.MultiRNNCell([lstm_cell(reuse) for _ in range(num_layers)]), attention_mechanism = attention, attention_layer_size = size_layer)

Answer 2

这可能是因为根据documentation，在API 1.11.0中，tf.contrib.seq2seq中没有{}。在

他们在release 1.3.0中添加了单调的注意力包装
