大神，好，训练模型后如何使用模型呢？意思是如何输入一个句子进行测试呢？

[forever1dream]

项目使用的是bazel编译，比较麻烦，修改一下seg_backend_api.cc 这个文件，如下：

	}

	//std::cout << "status" << std::endl;;
	//std::cout << "msg" << desc << std::endl;
}

return 0;

}
然后 自己写个编译命令编译，就可以直接运行，如下：
#!/bin/bash

set -e -x

注意修改下 自己的代码库路径

@forever1dream 能再解释下上面的方法吗？为何不用bazel编译，然后具体使用依然不懂啊？

[forever1dream]

@AlleyEli 我是觉得用bazel编译比较麻烦，而且集成到自己的项目中比较麻烦，上面的方法主要是弄清楚解码所需要的依赖 -I是依赖的头文件，-L是所需的.a或者.so 可以直接根据这个些makefile或者其他的，修改的代码主要是将源码中的网络服务去掉，改成，本地输入测试，或者文件测试

[AlleyEli]

@forever1dream 非常感谢！

[AlleyEli]

@forever1dream 能告诉下训练和使用时候环境吗?
我的Ubuntu16.04 + python2.7 + bzel0.45 + tf1.7.0
我对比下

我是centos7，python2.7，bazel0.9.0，tf1.6，你编译出.so了吗，安装那个脚本就可以了啊

[AlleyEli]

@forever1dream thanks
我自己用python封装了一套训练加使用的接口(https://github.com/AlleyEli/kcws), 测试也通过了;
主要是对比下环境,之前因为版本兼容问题,困扰好久,所以想看看你的运行环境

[forever1dream]

@AlleyEli 我把整个编译过程也放到github(https://github.com/forever1dream/cplus-kcws) 修改下自己的tensorflow安装路径（把该项目和tensorflow安装路径放在同级目录，就可以了） 和 boost路径，就可以运行了。感谢你的Python训练方法，我再去看看，多谢啦。
