ollama embedding兼容OpenAI格式

ollama embeddings 端点：/api/embed，而非/embeddings，输出的格式与OpenAI不兼容，下面给出兼容的方式。推荐模型： bge-m3

import json

# Ollama 嵌入数据
ollama_embeddings = {
    "model": "all-minilm",
    "embeddings": [
        [

# 转换为 OpenAI 嵌入输出格式
openai_embeddings = {
    "data": [
        {
            "embedding": embedding,
            "index": index,
            "object": "embedding"
        }
        for index, embedding in enumerate(ollama_embeddings["embeddings"])
    ]
}

# 打印转换后的 JSON 格式
print(json.dumps(openai_embeddings, indent=2))

输出结果：

  "data": [
    {
      "embedding": [
