使用样例

限制与约束

Atlas 800I A2 推理产品和Atlas 300I Duo 推理卡支持此特性。
当前仅ChatGLM3-6B模型支持此特性。

操作步骤

本节以使用ChatGLM3-6B为例，介绍Function Call如何使用，使用Function Call时无需配置额外参数。

配置服务化参数config.json，启动服务化。

cd ${mindie-service安装路径}
vi conf/config.json
./bin/mindieservice_daemon

向服务发送请求，参数说明见推理接口章节。

请求样例：

根据模型返回的tool_calls调用相关的本地工具，使用assistant角色关联2中接口返回的tool_calls和id，并使用tool角色关联工具执行的结果和2中接口返回的id，向大模型发送请求。
