 **\*Important\*** When finished installing Paddle Fluid, remember to update LD_LIBRARY_PATH about CUDA, cuDNN, NCCL2, for more information on paddlepaddle setup, you can click [here](http://en.paddlepaddle.org/documentation/docs/en/1.5/beginners_guide/index_en.html) and [here](http://en.paddlepaddle.org/documentation/docs/en/1.5/beginners_guide/install/install_Ubuntu_en.html). Also, you can read FAQ at the end of this document when you encounter errors.

 ## PaddlePaddle安装
 
-本项目依赖于 Paddle 1.6.3，* 由于Paddle 1.6.3版本相比之前版本有较大API改动，使用Paddle 1.6.3以前版本运行本代码库会导致序列标注等任务报错 *，请参考[安装指南](http://www.paddlepaddle.org/#quick-start)进行安装。

 **【重要】安装后，需要及时的将 CUDA、cuDNN、NCCL2 等动态库路径加入到环境变量 LD_LIBRARY_PATH 之中，否则训练过程中会报相关的库错误。具体的paddlepaddle配置细节请查阅[这里](http://en.paddlepaddle.org/documentation/docs/zh/1.5/beginners_guide/quick_start_cn.html)**
