 2、Add **batch_size** in my code, and **Supporting Multi-GPU Parallel Operations**.  
 All of my experiments are running in two TITAN XP GPUs. The batch_size is 6, the max len is 48 and the max Image size is 100000. You can try larger if you have enough GPU memory.

+4、Although the code is much better now than before, there are still many improvements. For example, you can try different optimization functions(Now is SGD) or different batch_size. If you have some good ideas and improve the results, you can contact to me. Meanwhile, I will also try some different and always pay attention to my code.
