我想在不使用MultiRNNCell的情况下制作多层RNN,因为我想独立更新每个图层。所以我没有使用tf.dynamic_rnn。Tensorflow RNN variable_scope error
with tf.variable_scope("cell"):
with tf.variable_scope("cell_1", reuse=True):
cell_1 = tf.contrib.rnn.BasicLSTMCell(n_hidden)
states_1 = cell_1.zero_state(batch_size, tf.float32)
with tf.variable_scope("cell_2", reuse=True):
cell_2 = tf.contrib.rnn.BasicLSTMCell(n_hidden)
states_2 = cell_2.zero_state(batch_size, tf.float32)
with tf.variable_scope("cell_3", reuse=True):
cell_3 = tf.contrib.rnn.BasicLSTMCell(n_hidden)
states_3 = cell_3.zero_state(batch_size, tf.float32)
outputs_1=[]
outputs_2=[]
outputs_3=[]
with tf.variable_scope("architecture"):
for i in range(n_step):
output_1, states_1 = cell_1(X[:, i], states_1)
output_2, states_2 = cell_2(output_1, states_2)
output_3, states_3 = cell_3(output_2, states_3)
outputs_3.append(output_3)
然后我得到这样的错误。
ValueError: Variable architecture/basic_lstm_cell/kernel already exists, disallowed. Did you mean to set reuse=True in VarScope?
因此,似乎不可能在没有MultiRNNCell的情况下声明张量流中的多个单元。我该如何解决这个问题?
