示例详述Docker部署tensorflow-serving

Docker简单入门

一、前言

工作中,有时需要线下验证训练好的模型,是否能在线上serving成功,所以需要利用docker来简单部署tensorflow-serving,然后线下进行验证模型能否成serving,避免出现模型过大,tensorflow-serving版本不对等情况,导致serving失败。

二、Docker部署tf-serving步骤

1、Docker安装(详见Docker简单入门

2、拉取tensorflow-serving镜像

tensorflow-serving是向下兼容的,所以可拉取最近的

#默认是latest 其中registry.docker-cn.com为官方中国区镜像加速
docker pull registry.docker-cn.com/tensorflow/serving 

 3、准备好模型(pb格式),如下图

示例详述Docker部署tensorflow-serving

放置某目录,如: /tfserving/tf15img/100/    (这里需要注意,pb模型上级目录必须是个版本号,也就是说,上级目录名称必须是数字,如:这里是100)

4、利用上面下载好的镜像启动tf_serving服务

#输入该命令
docker run -p 8501:8501 --mount type=bind,source=/tfserving/tf15img/,target=/models/ctrcvr -e MODEL_NAME=ctrcvr -t tensorflow/serving

-p:         指定主机到docker容器的端口映射

--mount:   表示要进行挂载
source:    要部署的模型地址
target:     模型挂载到docker容器中的目录
-t:         指定挂载到目标容器
-e:        指定模型名称
docker run: 启动这个容器并启动模型服务

启动成功效果:

5、调用,另开一个shell窗口,输入下面命令:

curl -X POST \
  http://localhost:8501/v1/models/ctrcvr:predict \
  -d '{
  "signature_name": "serving_default",
  "instances":[
     {
       "device_t": ["ios"],
       "device_b": ["apple"],
       "device_m": ["iphone_se"],
       "network": ["1"],
       "system": ["ios"],
       "city_id": ["5350937"],
       "goodsid_clicks": ["653389", "675647", "705347", "525684", "773155"],
       "goodsid_collects": ["653389"],
       "goodsid_carts": ["653389"],
       "content": ["cases", "iphone", "xs", "max", "", ""]
     }]}'

 6、最后输出的结果
