假设你已经搭建了modelbox开发容器能够使用webUI构建流程图。如果没有请参考昇腾npu上构建modelbox webUI开发容器教程。
现在本文会说明如何在终端用命令的方式将流程图暴露为服务并能够在本地用postman访问。 本文参考ModelBox运行的通过modelbox命令启动一节 主要流程
首先假设我们编写了如图的程序其中foobar阶段会固定输出一个字符串。
foobar.py内容如下固定会输出Hello world!
import _flowunit as modelboxclass FoobarFlowUnit(modelbox.FlowUnit):# Derived from modelbox.FlowUnitdef __init__(self):super().__init__()def open(self, config):# Open the flowunit to obtain configuration informationreturn modelbox.Status.StatusCode.STATUS_SUCCESSdef process(self, data_context):# Process the data# input datain_data data_context.input(in_data)# output dataout_data data_context.output(out_data)# Example process code.# Remove the following code and add your own code here.for buffer in in_data:add_buffer modelbox.Buffer(self.get_bind_device(), Hello world!)out_data.push_back(add_buffer)return modelbox.Status.StatusCode.STATUS_SUCCESSdef close(self):# Close the flowunitreturn modelbox.Status()def data_pre(self, data_context):# Before streaming data startsreturn modelbox.Status()def data_post(self, data_context):# After streaming data endsreturn modelbox.Status()mnist_response.py的代码逻辑也很简单固定输出上一步骤的字符串内容如下
import _flowunit as modelbox
import numpy as np
import jsonclass MnistResponseFlowUnit(modelbox.FlowUnit):def __init__(self):super().__init__()def open(self, config):return modelbox.Status.StatusCode.STATUS_SUCCESSdef process(self, data_context):in_data data_context.input(in_data)out_data data_context.output(out_data)for buffer in in_data:add_buffer modelbox.Buffer(self.get_bind_device(), buffer.as_object())out_data.push_back(add_buffer)return modelbox.Status.StatusCode.STATUS_SUCCESSdef close(self):return modelbox.Status()def data_pre(self, data_context):return modelbox.Status()def data_post(self, data_context):return modelbox.Status()def data_group_pre(self, data_context):return modelbox.Status()def data_group_post(self, data_context):return modelbox.Status()然后在项目路径内graph/下的.toml文件内修改暴露的端口如下文显示端口暴露在8190 … digraph mnist_sample { node [shapeMrecord] httpserver_sync_receive [ typeflowunit flowunithttpserver_sync_receive devicecpu time_out_ms“5000” endpoint“http://0.0.0.0:8190” max_requests“100” ] … 那么如何不用webUI将流程图启动暴露为Restful服务呢 进入modelbox开发容器 进入目录/root/modelbox-service/conf 编辑modelbox.conf配置文件。把flow_path 属性指向你的项目的graph目录比如在本文的mnist项目流程图存储在/root/projects/mnist/src/graph目录下。内容如下 [server]
ip 0.0.0.0
port 1104
flow_path /root/projects/mnist/src/graph/# 后续略...执行modelbox -c ./modelbox-service/conf/modelbox.conf -fV。如果在子目录下则执行modelbox -c ./modelbox.conf -fV
然后能看到终端输出日志
[rootdevserver-com conf]$ modelbox -c ./modelbox.conf -fV
