长久以来,python接入星火大模型没有一个统一官方维护的Library, 此番开源本sdk,也是为了能够让星火大模型更快落到实际的一些AI大模型应用相关的开发任务中去,简化python用户调用大模型成本。
目前基于Langchain的一些基础数据类型移植开发得到本项目,部分核心实现如有雷同,纯属"学习"! 感谢开源的力量,希望讯飞开源越做越好,星火大模型效果越来越好!。

handler = ChunkPrintHandler()
a = spark.generate([messages], callbacks=[handler])
print(a)
其中 ChunkPrintHandler
为回调类,可以在回调类处理流式响应的chunk,
该类简单实现如下:
class ChunkPrintHandler(BaseCallbackHandler):
"""Callback Handler that prints to std out."""
def __init__(self, color: Optional[str] = None) -> None:
"""Initialize callback handler."""
self.color = color
def on_llm_new_token(self, token: str,
*,
chunk: None,
**kwargs: Any,):
print(token)
print(kwargs)
# token 为模型生成的token
# 可以check kwargs内容,kwargs中 llm_output中有usage相关信息, final表示是否是最后一帧
上述在 on_llm_new_token 实现您的流式处理逻辑,如需定制流式处理逻辑,请参考上述实现,继承: BaseCallbackHandler
直接遍历生成器(同步stream接口):
def test_starcoder2():
from sparkai.log.logger import logger
#logger.setLevel("debug")
from sparkai.core.callbacks import StdOutCallbackHandler
messages = [{'role': 'user',
'content': "帮我生成一段代码,爬取baidu.com"}]
spark = ChatSparkLLM(
spark_api_url="wss://xingchen-api.cn-huabei-1.xf-yun.com/v1.1/chat",
spark_app_id=os.environ["SPARKAI_APP_ID"],
spark_api_key=os.environ["SPARKAI_API_KEY"],
spark_api_secret=os.environ["SPARKAI_API_SECRET"],
spark_llm_domain="xsstarcoder27binst",
streaming=True,
max_tokens= 1024,
)
messages = [
ChatMessage(
role="user",
content=messages[0]['content']
)]
a = spark.stream(messages)
for message in a:
print(message)
或者是异步astream接口:
async def test_astream():
from sparkai.log.logger import logger
#logger.setLevel("debug")
from sparkai.core.callbacks import StdOutCallbackHandler
messages = [{'role': 'user',
'content': "帮我生成一段代码,爬取baidu.com"}]
spark = ChatSparkLLM(
spark_api_url="wss://xingchen-api.cn-huabei-1.xf-yun.com/v1.1/chat",
spark_app_id=os.environ["SPARKAI_APP_ID"],

spark_api_secret=os.environ["SPARKAI_API_SECRET"],
spark_llm_domain="xsstarcoder27binst",
streaming=True,
max_tokens= 1024,
)
messages = [
ChatMessage(
role="user",
content=messages[0]['content']
)]
handler = AsyncChunkPrintHandler()
a = spark.astream(messages, config={"callbacks": [handler]})
async for message in a:
print(message)
if __name__ == '__main__':
import asyncio
asyncio.run(test_astream())
比如将 mulitply 乘法函数定义传入 ChatSparkLLM
from sparkai.core.utils.function_calling import convert_to_openai_tool, convert_to_openai_function
def multiply(a,b :int) -> int:
"""你是一个乘法计算器,可以帮我计算两个数的乘积,例如:计算1乘1等于几或计算1*1等于几
Args:
a: 输入a
b: 输入b
Return:
返回 a*b 结果
"""
print("hello success")
return a*b
def test_function_call():
from sparkai.core.callbacks import StdOutCallbackHandler
messages = [{'role': 'user',
'content': "帮我算下 12乘以12"}]
spark = ChatSparkLLM(
spark_api_url=os.environ["SPARKAI_URL"],
spark_app_id=os.environ["SPARKAI_APP_ID"],
spark_api_key=os.environ["SPARKAI_API_KEY"],
spark_api_secret=os.environ["SPARKAI_API_SECRET"],
spark_llm_domain=os.environ["SPARKAI_DOMAIN"],
streaming=False,
)
function_definition =[convert_to_openai_function(multiply)]
print(json.dumps(convert_to_openai_tool(multiply),ensure_ascii=False))
messages = [ChatMessage(
role="user",
content=messages[0]['content']
)]
handler = ChunkPrintHandler()
a = spark.generate([messages], callbacks=[handler],function_definition=function_definition)
print(a)
print(a.generations[0][0].text)
print(a.llm_output)
得到输出
PASSED [100%]{"type": "function", "function": {"name": "multiply", "description": "乘法函数,\nArgs:\n a: 输入a\n b: 输入b\nReturn:\n 返回 a*b 结果", "parameters": {"type": "object", "properties": {"b": {"type": "integer"}}, "required": ["a", "b"]}}}
generations=[[ChatGeneration(message=FunctionCallMessage(content='', function_call={'arguments': '{"a":12,"b":12}', 'name': 'multiply'}))]] llm_output={'token_usage': {'question_tokens': 9, 'prompt_tokens': 9, 'completion_tokens': 0, 'total_tokens': 9}} run=[RunInfo(run_id=UUID('95bf4e2e-6c90-41aa-9ddf-51b707d4d3c7'))]

仅供用于调试或者应用于三方框架快速集成星火
python -m sparkai.spark_proxy.main
运行后如下:
INFO: Started server process [57295]
INFO: Waiting for application startup.
INFO: Application startup complete.
INFO: Uvicorn running on http://0.0.0.0:8008 (Press CTRL+C to quit)
之后再需要配置OPENAI
配置上述 本地url 和 星火 key&secret&appid"
组成的key即可以openai接口形式调用星火大模型
- open_api_key: 配置格式key为:
key&secret&appid"
格式的key - openai_base_url: 你本地 ip:8008端口
具体操作流程参见本地代理方式星火SparkAPI转OpenAI接口

- 项目目前开发阶段,有一些冗余代码,人力有限,部分思想借鉴开源实现
- Client当前不支持多路复用,多线程使用时, 每个线程需要单独实例化Client
- 当前流式接口不支持每帧统计token数量,需要sparkapi正式支持该特性后, sdk会同步支持。
