这个是官方教程 https://github.com/PaddlePaddle/Serving/tree/develop/python/examples/ocr

按照教程安装好依赖，执行 python3 rec_web_server.py 得到报错 cannot import name 'GetRotateCropImage' from 'paddle_serving_app.reader' 刚刚看了源码，这个错误是因为没有及时更新 paddle_serving_app 包，教程出来了，代码没跟上。。。。。。

rec_web_server.py 实际上不需要依赖 paddle_serving_app 这些东西，清除不需要的依赖后，可以跑起来了。

模拟发送请求 python3 rec_web_client.py 得到以下错误：
