报错

ValueError: Variable hello/rnn/basic_lstm_cell/weights already exists, disallowed. Did you mean to set reuse=True in VarScope? Originally defined at

因为之前的cell kernel还在运行，如果使用的两个不同的cell，用variable scope指明

with tf.variable_scope('forward'):     self.lstm_fw_cell = rnn_cell.BasicLSTMCell(dim_hidden)    with tf.variable_scope('backward'):     self.lstm_bw_cell = rnn_cell.BasicLSTMCell(dim_hidden)

如果使用的是相同的cell，将cell中的reuse设为True

rnn.BasicLSTMCell(num_hidden, forget_bias=1.0, reuse = True)
