Customer Open-AI alike API Support #1

Open yfyang86 opened 11 months ago

🚀 The feature

Customer Open-AI alike API Support

Per anhp's request: https://github.com/gventuri/pandas-ai/issues/799#issue-2022067003

Motivation, pitch

For example, LM-Studio's example:

curl http://localhost:1378/v1/chat/completions \
-H "Content-Type: application/json" \
-d '{ 
  "messages": [ 
    { "role": "system", "content": "Always answer in rhymes." },
    { "role": "user", "content": "Introduce yourself." }
  ], 
  "temperature": 0.7, 
  "max_tokens": -1,
  "stream": false
}

Alternatives

No response

Additional context

I've added some examples with some screenshots of settings cust-openai. Please checkout the cust-openai branch (my fork).

git clone https://github.com/yfyang86/pandas-ai
cd pandas-ai
git checkout cust-openai
git pull
python -m pip install .
yfyang86 commented 11 months ago

Check cust-openai branch.

Please do notice: the prompts used should be modified accordingly as the open source LLM is not strong/stable enough.

Meddebma commented 10 months ago

Dear @yfyang86,

thank for your fork, I just installed it, but I do have troubles connecting my LLM from Studio to it, when I pass llm = CustOpenAI(api_base="http://localhost:1234/v1", api_token="null", model_name="local-model")

I still get the error AuthenticationError: Error code: 401 - {'error': {'message': 'Incorrect API key provided: OPENAI_A****OKEN. You can find your API key at https://platform.openai.com/account/api-keys.', 'type': 'invalid_request_error', 'param': None, 'code': 'invalid_api_key'}}

Which valid syntax should I use?

Thanks for helping, Best, Aymen

@yfyang86 If you can see this loads of people want to try this. Every single time we get blocked by hte API key issue.

clearsitedesigns commented 9 months ago

Yes we would love to know this, can't figure out how to get around the API KEY need, Litteraly 20 + people asking about this.

Example: reuse your existing OpenAI setup

from openai import OpenAI

Point to the local server

client = OpenAI(base_url="http://localhost:1234/v1", api_key="not-needed")

completion = client.chat.completions.create( model="local-model", # this field is currently unused messages=[ {"role": "system", "content": "Always answer in rhymes."}, {"role": "user", "content": "Introduce yourself."} ], temperature=0.7, )

print(completion.choices[0].message)

yfyang86 commented 9 months ago

I will work on this and add an end-to-end example on this weekend.

Hi, I added this class to base.py and it worked:

class LMStudio(LLM): """Class to implement local LMStudio API

"""

last_prompt: Optional[str] = None
_model = "local-model"
_api_token: str = "not-needed"
_api_url: str = "http://localhost:1234/v1/chat/completions"
_temp = 0.7
_max_retries: int = 3
_stream = False

@property
def type(self) -> str:
    return "local-llm"

def __init__(self, api_url=_api_url, stream=_stream, temp=_temp):
    """
    __init__ method of LMStudio Class

    """
    self.api_url = api_url
    self.stream = stream
    self.temp = temp

def query(self, payload) -> str:
    """
    Query the local LMSTudio API

    """

    headers = {
        "Content-Type": "application/json",
        "Authorization": f"Bearer {self._api_token},",
    }

    response = requests.post(self._api_url, headers=headers, data=json.dumps(payload))

    if response.status_code >= 400:
        try:
            error_msg = response.json().get("error")
        except (requests.exceptions.JSONDecodeError, TypeError):
            error_msg = None

        raise LLMResponseHTTPError(
            status_code=response.status_code, error_msg=error_msg
        )

    result = response.json()
    return result["choices"][0]["message"]["content"]

def call(self, instruction: AbstractPrompt, suffix: str = "") -> str:
    """
    A call method of LMStudio class.
    Args:
        instruction (AbstractPrompt): A prompt object with instruction for LLM.
        suffix (str): A string representing the suffix to be truncated
            from the generated response.

    Returns
        str: LLM response.

    """

    prompt = instruction.to_string() + suffix
    payload = {
    "model": LMStudio._model,
    "messages": [{
    "role": "system", 
    "content": prompt,
    }],
    "temperature": self.temp,
    "stream": self.stream,
    }

    # sometimes the API doesn't return a valid response, so we retry passing the
    # output generated from the previous call as the input
    for _i in range(self._max_retries):
        response = self.query(payload)
        payload = response

        match = re.search(
            "(```python)(.*)(```)",
            response.replace(prompt + suffix, ""),
            re.DOTALL | re.MULTILINE,
        )
        if match:
            break

    return response.replace(prompt + suffix, "")

Here usage:

from pandasai.llm.base import LMStudio from pandasai import SmartDataframe import pandas as pd

llm = LMStudio(api_url="http://localhost:1234/v1")

df = pd.DataFrame({ "country": ["United States", "United Kingdom", "France", "Germany", "Italy", "Spain", "Canada", "Australia", "Japan", "China"], "gdp": [19294482071552, 2891615567872, 2411255037952, 3435817336832, 1745433788416, 1181205135360, 1607402389504, 1490967855104, 4380756541440, 14631844184064], "happiness_index": [6.94, 7.16, 6.66, 7.07, 6.38, 6.4, 7.23, 7.22, 5.87, 5.12] })

df_llm = SmartDataframe(df, config={"llm": llm}) print(df_llm.chat('What is the least happy country?'))

Output: The least happy country is China.

clearsitedesigns commented 9 months ago

Awesome I spent last night working on this again, the data frame refuses to load I modified the open ai class to get around the token issue, but the data frame refuses to chat or pass into the llm_local

I will try this again shortly

clearsitedesigns commented 9 months ago

Ok that worked with some strange behavior. If you run the request one time, and use the same smart dataframe - it will not for some reason invoke the LLM again, Unless you change the data in the frame, It almost seems like the dataframe is cached? When the script is run every time it doesn't always connect to the LM it just answers - which is curious

Yep that looks like the issue:

df_llm = SmartDataframe(df, config={"llm": llm, "enable_cache": False})

Should clear the cache

yfyang86 commented 9 months ago

Please check my solution (https://github.com/yfyang86/pandas-ai/tree/cust-openai):

   ...: _port_number_ = '1378'
   ...: _llm_version_ = 'v1'
   ...: llm = CustOpenAI(api_base = f"{_host_url_}:{_port_number_}/{_llm_version_}", api_token = "null")
   ...:

! Please do notice, there should be (possible fake) information leak in the above answer. In this case, I use the mixtral MoE 8x7B-Q4_0 as an example model.

Hi, thank you for the answer.

I use Python 3.11 but still get the API key error, I'm not sure if I'm doing something wrong? Could you explain further to me, what you mean with "LM-studio only works on chat-completion mode, and client.completion.create misbehaves."? It seems to work for me sometimes with the new implemented Class, but it often gets coding errors, I thought maybe because the LLM is not as good in coding. And what do you mean with "there should be (possible fake) information leak in the above answer" ?

Thank you, it would help me a lot if you could explain :D @yfyang86
