# Local LLM Server for Semantic Kernel .NET Developer
*如果你使用中文，请[访问这里](README.zh-cn.md)*
*Support Semantic-Kernel 1.0.1*
Or you are using Semantic Kernel's [Hugging Face http server](https://github.com/microsoft/semantic-kernel/tree/3451a4ebbc9db0d049f48804c12791c681a326cb/samples/apps/hugging-face-http-server) as your local LLM service , but based on the inaccessibility of hugging face in mainland China and management reasons, I tried to reconstruct the project. At this stage, it is adapted for macOS and Linux environments.
At this stage, the implementation of ChatCompletion and Embedding has been completed.
**ChatCompletion** is adapted to LLM *baichu2*, *ChatGLM3*, *Microsoft-phi 1.5*
**Embeddings** adapted to LLM *jina-embeddings* (English Embedding model), *text2vec-large-chinese* (Chiense Embedding model), *bge-\*-v1.5*(Chinese/English Embedding model)
**Samples**
0. download your LLM firstly and using pip to install python library
```bash
pip install -r requirement.txt
```
1. .env config your ChatCompletion and Embedding model location
```txt
CHAT_COMPLETION_URL = 'Your chat completion model location'
EMBEDDING_URL = 'Your embeddings model location'
```
2. Start your Local LLM Http Server
```bash
python local_llm_service.py
```
3. Add Microsoft.SemanticKernel, Microsoft.SemanticKernel.Connectors.AI.HuggingFace, Microsoft.SemanticKernel.Connectors.Memory.Qdrant(You can choose different vector database) packages
4. Initialization endpoint for chatcompletion, embeddings, and qdrant
```csharp
string chat_endpoint = "http://localhost:5002/v1/chat/completions";
string embeddings_endpoint = "http://localhost:5002/v1/embeddings";
string qdrant_endpoint = "http://localhost:6333";
```
5. Sample 1 - ChatCompletion
```csharp
using Microsoft.SemanticKernel;
using Microsoft.SemanticKernel.Connectors.Memory.Qdrant;
using Microsoft.SemanticKernel.Plugins.Memory;
using Microsoft.SemanticKernel.Connectors.AI.HuggingFace.TextEmbedding;
#pragma warning disable SKEXP0020
Kernel kernel = new KernelBuilder()
.AddHuggingFaceTextGeneration(
model: "baichuan2",
endpoint: chat_endpoint)
.Build();
var questionAnswerFunction = kernel.CreateFunctionFromPrompt("问: {{$input}} 答:");
var result = await kernel.InvokeAsync(questionAnswerFunction, new("介绍一下自己"));
result.GetValue()
```
6. Sample 2 - Embeddings
```csharp
#pragma warning disable SKEXP0052
#pragma warning disable CS1061
#pragma warning disable SKEXP0011
#pragma warning disable SKEXP0026
#pragma warning disable SKEXP0020
var qdrantMemoryBuilder = new MemoryBuilder();
var hfembeddings = new HuggingFaceTextEmbeddingGeneration("text2veccn", embeddings_endpoint);
qdrantMemoryBuilder.WithTextEmbeddingGeneration(hfembeddings);
qdrantMemoryBuilder.WithQdrantMemoryStore(qdrant_endpoint, 1024);
var builder = qdrantMemoryBuilder.Build();
string MemoryCollectionName = "text2vecdemo";
await builder.SaveInformationAsync(MemoryCollectionName, id: "id1", text: "我是卢建晖");
await builder.SaveInformationAsync(MemoryCollectionName, id: "id2", text: "卢建晖是微软云技术布道师");
await builder.SaveInformationAsync(MemoryCollectionName, id: "id3", text: "卢建晖从 2012 年到 2020 年是微软最有价值专家");
await builder.SaveInformationAsync(MemoryCollectionName, id: "id4", text: "卢建晖是人工智能讲师");
var searchResults = builder.SearchAsync(MemoryCollectionName, "你认识卢建晖吗", limit: 3, minRelevanceScore: 0.6);
await foreach (var item in searchResults)
{
Console.WriteLine(item.Metadata.Text + " : " + item.Relevance);
}
```
