设置

如果您希望从单个工具的运行中获得自动跟踪，请设置您的 LangSmith API 密钥：

export LANGSMITH_TRACING="true"
export LANGSMITH_API_KEY="your-api-key"

安装

此工具包位于 @langchain/ibm 包中：

请参阅 有关安装 LangChain 包的一般说明。

npm

npm install @langchain/ibm @langchain/core

实例化

现在我们可以实例化我们的工具包：

import { WatsonxToolkit } from "@langchain/ibm";
import "dotenv/config"

const toolkit = await WatsonxToolkit.init({
   version: '2024-05-31',
   serviceUrl: process.env.WATSONX_AI_SERVICE_URL
});

[Module: null prototype] { default: {} }

工具

查看可用工具：

const tools = toolkit.getTools();

console.log(tools.map((tool) => ({
   name: tool.name,
   description: tool.description,
})))

[
 {
 name: "GoogleSearch",
 description: "Search for online trends, news, current events, real-time information, or research topics."
 },
 {
 name: "WebCrawler",
 description: "Useful for when you need to summarize a webpage. Do not use for Web search."
 },
 {
 name: "SDXLTurbo",
 description: "Generate an image from text using Stability.ai"
 },
 { name: "Weather", description: "Find the weather for a city." },
 {
 name: "RAGQuery",
 description: "Search the documents in a vector index."
 }
]

在智能体中使用

安装 langchain 包以使用 createAgent：

npm

npm install langchain @langchain/ibm @langchain/core

然后，实例化您要在智能体中使用的 LLM：

import { ChatWatsonx } from "@langchain/ibm";

const llm = new ChatWatsonx({
   version: '2024-05-31',
   serviceUrl: process.env.WATSONX_AI_SERVICE_URL,
   model: 'ibm/granite-3-8b-instruct',
   projectId: process.env.WATSONX_AI_PROJECT_ID
});

import { createAgent } from "langchain";

const agent = createAgent({ model: llm, tools });

const exampleQuery = "Who won F1 championship in 2022?"

const stream = await agent.streamEvents(
  { messages: [{ role: "user", content: exampleQuery }] },
  { version: "v3" },
);

for await (const snapshot of stream.values) {
  const lastMsg = snapshot.messages[snapshot.messages.length - 1];
  if (lastMsg.tool_calls?.length) {
    console.dir(lastMsg.tool_calls, { depth: null });
  } else if (lastMsg.content) {
    console.log(lastMsg.content);
  }
}

Who won F1 championship in 2022?
[
 {
 name: "GoogleSearch",
 args: { input: "F1 championship 2022" },
 type: "tool_call",
 id: "chatcmpl-tool-9da3456b9bbc475fb822296fdb8353a8"
 }
