Reproduction

Modified example code (https://python.langchain.com/docs/integrations/llms/azure_openai) from langchain to access AzureOpenAI inferencing endpoint

import os

os.environ["OPENAI_API_TYPE"] = "azure"
os.environ["OPENAI_API_VERSION"] = "2023-05-15"
os.environ["OPENAI_API_BASE"] = "..."
os.environ["OPENAI_API_KEY"] = "..."

# Import Azure OpenAI
from langchain.llms import AzureOpenAI

# Create an instance of Azure OpenAI
# Replace the deployment name with your own
llm = AzureOpenAI(
    deployment_name="td2",
    model_name="text-davinci-002",
)

# Run the LLM
llm("Tell me a joke")

I get the following error: TypeError: Missing required arguments; Expected either ('model' and 'prompt') or ('model', 'prompt' and 'stream') arguments to be given

If I modify the last line as follows: llm("Tell me a joke", model="text-davinci-002") i get a different error: Completions.create() got an unexpected keyword argument 'engine'

It appears to be passing all keywords to the create method, the first of which is 'engine', and it appears that and other kws are being added by the code.

Expected behavior

I expect the model to return a response, such as is shown in the example.

Hello @rockman25!

I'm here to assist you while we wait for a human maintainer. As an AI, I'm equipped to help you solve bugs, answer questions, and guide you on how to contribute to this project.

Now, let's take a look at the issue you've raised. I'll provide a full answer shortly. Stay tuned!

Based on the error message you're receiving, it seems like there might be a mismatch between the arguments expected by the AzureOpenAI instance and the ones you're providing.

In the LangChain codebase, the AzureOpenAI instance requires specific parameters such as azure_deployment, openai_api_version, openai_api_key, azure_ad_token, etc. These parameters can be set either in your environment variables or directly in the constructor.

Here's how you can modify your code:

import os

os.environ["OPENAI_API_TYPE"] = "azure"
os.environ["OPENAI_API_VERSION"] = "2023-05-15"
os.environ["OPENAI_API_BASE"] = "..."
os.environ["OPENAI_API_KEY"] = "..."

# Import Azure OpenAI
from langchain.llms import AzureOpenAI

# Create an instance of Azure OpenAI
# Replace the deployment name with your own
llm = AzureOpenAI(
    azure_deployment="td2",
    openai_api_version="2023-05-15",
    openai_api_key="...",
    model_name="text-davinci-002",
)

# Run the LLM
response = llm.run(prompt="Tell me a joke")

In the above code, I've added the azure_deployment, openai_api_version, and openai_api_key parameters to the AzureOpenAI constructor. Also, I've replaced llm("Tell me a joke") with llm.run(prompt="Tell me a joke") as the run method is the correct way to execute the model.

If you're still encountering issues, it would be helpful if you could provide the exact error message and the line of code where the error is occurring. This will allow me to give a more accurate solution.

@dosu-bot This does not work. In fact, I get an error message saying 'AzureOpenAI' object has no attribute 'run'.

[dosubot[bot]]

🤖

Based on the context provided, it appears that the error you're encountering is due to the fact that the 'AzureOpenAI' class from the langchain.llms module in the LangChain Python framework does not have a 'run' method defined in it.

In the LangChain codebase, the 'AzureOpenAI' class is defined with several methods such as '_astream', '_generate', and 'completion_with_retry', but none of them is named 'run'. This is why you're getting an error when you try to call 'run' on an instance of the 'AzureOpenAI' class.

To resolve this issue, you need to call a method that is defined in the 'AzureOpenAI' class. If you're trying to execute a chat completion, you might need to use the '_generate' method or another appropriate method that supports this functionality.

Here's an example of how you might modify your code to use the '_generate' method:

# Run the LLM
response = llm._generate(prompt=["Tell me a joke"])

Please note that the '_generate' method expects a list of prompts, so you'll need to pass your prompt as a list.

If you believe that a 'run' method should exist in the 'AzureOpenAI' class, then it's possible that the method was removed in the version of LangChain you're using (0.0.335). In this case, you should check the documentation or source code of the LangChain framework for the version you're using to see if the 'run' method should exist. If the 'run' method is not supposed to be part of the 'AzureOpenAI' class, then you'll need to update your code to not call 'run' on an instance of the 'AzureOpenAI' class.

You can find more information about the methods available in the 'AzureOpenAI' class in the LangChain codebase in the context provided above.

@dosu-bot Two problems with the latest solution: the argument should be 'prompts', not 'prompt'. But worse is when I use the correct argument I get the same error I started with--it's looking for a second argument, which is 'model'. But if I add that, now it once again gives an error saying Completions.create() got an unexpected keyword.

Based on the information you've provided and the context from the LangChain repository, it seems like the issue you're encountering is due to the arguments you're passing to the _generate method of the AzureOpenAI class.

The _generate method of the AzureOpenAI class accepts the following arguments:

• prompts: A list of strings
• stop: An optional list of strings
• run_manager: An optional instance of CallbackManagerForLLMRun
• **kwargs: Any additional keyword arguments

If you're passing an argument that is not one of these, you will encounter an error.

Here's an example of how to correctly use the _generate method:

from langchain.llms import AzureOpenAI
from langchain.callbacks.manager import CallbackManagerForLLMRun

azure_openai = AzureOpenAI(model_name="text-davinci-003")
run_manager = CallbackManagerForLLMRun()

prompts = ["Hello, how are you?"]
stop = ["?"]

result = azure_openai._generate(prompts, stop, run_manager)

Please ensure that the arguments you're passing to the _generate method match the expected arguments. If the error persists, could you please provide the exact error message and the code you're using to call the _generate method for further assistance?

Also, I found a similar issue in the LangChain repository titled Unable to use gpt4all model which was resolved by a pull request: Update GPT4ALL integration. You might find the discussion and solution there helpful.

Let me know if this helps or if you need further assistance.

[playermanny2]

same issue here, seems like the new APIs for openai has broken this; and also the langchain docs are out dated

[gcpdev]

I can confirm the problem, as I am facing the same issue at the moment by using AzureOpenAI in langchain 0.0.335.

@playermanny2 @rockman25 as a workaround use: !pip install langchain==0.0.242 !pip install pip install openai==0.28

[fenilvanvi-ifix]

I also faced the same issue yesterday. Today, I upgraded the langchain and openai versions. Now, it is working fine.

@rockman25 !pip install langchain==0.0.336 !pip install openai==1.3.0

[aht]

Works fine after upgrading to langchain==0.0.339 now.

Is there a working tutorial for python and chatgpt anywhere?

@rockman25 I had the same problem except I was using a deepseek coder local LLM from LM studio and I managed to fix it by adding a parameter called "model":"deepseek-ai_deepseek-coder-6.7b-instruct" (on line 5).

from autogen import AssistantAgent, UserProxyAgent, config_list_from_json

config_list = [
    {
        **"model":"deepseek-ai_deepseek-coder-6.7b-instruct",**
        "base_url": "http://localhost:1234/v1",
        "api_key":"NULL"
    }
]

llm_config={
    "timeout": 600,
    "seed": 42,
    "config_list": config_list,
    "temperature": 0
}

assistant = AssistantAgent(
    name="Assistant",
    llm_config=llm_config,
    system_message="You are a coder specializing in Python."
)

user_proxy = UserProxyAgent(
    name="user_proxy",
    human_input_mode="NEVER",
    max_consecutive_auto_reply=10,
    is_termination_msg=lambda x: x.get("content", "").rstrip().endswith("TERMINATE"),
    code_execution_config={"work_dir": "web"},
    llm_config=llm_config,
    system_message="""Reply TERMINATE if the task has been solved at full satisfaction.
Otherwise, reply CONTINUE, or the reason why the task is not solved yet."""
)

task1 = """
Write python code to convert an input in roman numerals to decimal output.
"""

task2 = """
Explain the code written by the Assistant to convert roman numerals to decimal.
"""

user_proxy.initiate_chat(
    assistant,
    message=task1
)

user_proxy.initiate_chat(
    assistant,
    message=task2
)

I'm not sure how this plays into AzureOpenAI because I'm just a beginner programmer 😅 but hopefully it helps in some way.
