I am using code from langchain example but got an error:

import { MemoryVectorStore } from "langchain/vectorstores/memory";
 import { LLamaEmbeddings } from "llama-node/dist/extensions/langchain.js";
 import { LLama } from "llama-node";
 import { LLamaCpp } from "llama-node/dist/llm/llama-cpp.js";
 import path from "path";
 
 const model = path.resolve(process.cwd(), "llama-2-7b-chat.ggmlv3.q8_0.bin");
 
 const llama = new LLama(LLamaCpp);
 
 const config = {
     path: model,
     enableLogging: true,
     nCtx: 1024,
     nParts: -1,
     seed: 0,
     f16Kv: false,
     logitsAll: false,
     vocabOnly: false,
     useMlock: false,
     embedding: true,
     useMmap: true,
 };
 
 llama.load(config);
 
 const run = async () => {
     // Load the docs into the vector store
     const vectorStore = await MemoryVectorStore.fromTexts(
         ["Hello world", "Bye bye", "hello nice world"],
         [{ id: 2 }, { id: 1 }, { id: 3 }],
         new LLamaEmbeddings({ maxConcurrency: 1 }, llama)
     );
 
  const resultOne = await vectorStore.similaritySearch("hello world", 1);

  console.log(resultOne);
 };
 
 run().catch(error => {
     console.log(error)
 });

output: [1] 37742 segmentation fault node index.js

I guess this is because the Llama.cpp package has not been updated since the last release two month ago. You need a more recent Llama.cpp build to run Llama 2
