hub serving部署方案

 

 

 

 

 

 

 

 

 

 

 

 

 

 docker部署paddlepaddle和paddlehub和模型服务

#需要将PaddleHub和PaddlePaddle统一升级到2.0版本
!pip install paddlehub==2.0.0 -i https://pypi.tuna.tsinghua.edu.cn/simple 
!pip install paddlepaddle==2.0.0 -i https://pypi.tuna.tsinghua.edu.cn/simple 
#该Module依赖于第三方库shapely、pyclipper，使用该Module之前，请先安装shapely、pyclipper
!pip install shapely -i https://pypi.tuna.tsinghua.edu.cn/simple 
!pip install pyclipper -i https://pypi.tuna.tsinghua.edu.cn/simple

# 打印预测结果
