Failed to call ThenRnnForward with model config: [rnn_mode, rnn_input_mode, rnn_direction_mode]: 3,

成功解决代码运行出现的问题：

Failed to call ThenRnnForward with model config: [rnn_mode, rnn_input_mode, rnn_direction_mode]: 3, 0, 0 , [num_layers, input_size, num_units, dir_count, max_seq_length, batch_size, cell_num_units]: [1, 1, 100, 1, 196, 512, 0]

通过查看经验贴发现时batch_size太大了  ，调小一点就行了。
