Description

I am using ChatGoogleGenerativeAI along with AzureOpenAI in configurable mode.

I have written a simple fastapi to write a joke on user given topic. When I run the above code configuring my "llm" parameter as azure it works fine. However, when I run the same code with "llm" parameter as gemini the code fails with the below error:

Hello, @rvasa779! I'm here to assist you. If you need help with bugs, questions, or becoming a contributor, I'm the bot for the job.

The AttributeError: 'int' object has no attribute 'name' error you're encountering when using the gemini model is likely due to an issue with the structure or type of the data being passed to the ChatGoogleGenerativeAI model. Specifically, the finish_reason attribute in the _response_to_result function is expected to have a name attribute, but it seems to be an integer instead.

To resolve this issue, you need to ensure that the finish_reason attribute is correctly set and has the expected structure. Here is a potential fix:

1. Check the finish_reason Attribute: Ensure that the finish_reason attribute in the response from the gemini model is not an integer. It should be an object with a name attribute.

2. Modify the _response_to_result Function: Update the _response_to_result function to handle cases where finish_reason might be an integer. You can add a check to convert it to a string or handle it appropriately.

Here is an example of how you might modify the _response_to_result function:

def _response_to_result(response):
    result = {}
    for candidate in response.candidates:
        generation_info = {}
        if hasattr(candidate.finish_reason, 'name'):
            generation_info["finish_reason"] = candidate.finish_reason.name
        else:
            generation_info["finish_reason"] = str(candidate.finish_reason)
        result["generation_info"] = generation_info
    return result

This modification ensures that if finish_reason is an integer, it will be converted to a string, avoiding the AttributeError.

Additionally, ensure that the data_dict being passed to the img_prompt_func function contains the correct structure and types. Specifically, the data_dict["context"]["images"] should be a list of base64-encoded image strings, and data_dict['question'] should be a string.

Here is the relevant part of the code that needs to be checked and possibly corrected:

def img_prompt_func(data_dict, num_images=2):
    messages = []
    if data_dict["context"]["images"]:
        for image in data_dict["context"]["images"][:num_images]:
            image_message = {
                "type": "image_url",
                "image_url": {"url": f"data:image/jpeg;base64,{image}"},
            }
            messages.append(image_message)
    text_message = {
        "type": "text",
        "text": (
            "You are an analyst tasked with answering questions about visual content.\n"
            "You will be given a set of image(s) from a slide deck / presentation.\n"
            "Use this information to answer the user question. \n"
            f"User-provided question: {data_dict['question']}\n\n"
        ),
    }
    messages.append(text_message)
    return [HumanMessage(content=messages)]

Ensure that the data_dict passed to this function is structured correctly. For example:

data_dict = {
    "context": {
        "images": ["base64_encoded_image_string1", "base64_encoded_image_string2"]
    },
    "question": "What is shown in these images?"
}

If data_dict["context"]["images"] contains integers or any other type that does not have a name attribute, it will cause the AttributeError. Make sure that the images are properly base64-encoded strings ^[1].

The same code generates different types of response objects when invoked via Azure Function versus FastAPI because the response_content_type attribute in the GenericRequestsWrapper class determines the type of response content returned. This attribute can be set to either "text" or "json".

To ensure consistent behavior across both invocation methods, you need to explicitly set the response_content_type to the desired type ("text" or "json") in your wrapper class. For example, if you want to always return JSON responses, you should use the JsonRequestsWrapper class, which sets response_content_type to "json".

Here is an example of how to use the JsonRequestsWrapper to ensure consistent JSON responses:

from your_module import JsonRequestsWrapper

# Create an instance of JsonRequestsWrapper
requests_wrapper = JsonRequestsWrapper()

# Use the wrapper to make a GET request
response = requests_wrapper.get("https://api.example.com/data")

# The response will always be in JSON format
print(response)

Similarly, if you want to always return text responses, you should use the TextRequestsWrapper class:

from your_module import TextRequestsWrapper

# Create an instance of TextRequestsWrapper
requests_wrapper = TextRequestsWrapper()

# Use the wrapper to make a GET request
response = requests_wrapper.get("https://api.example.com/data")

# The response will always be in text format
print(response)

By using the appropriate wrapper class, you can ensure that the response type is consistent regardless of whether the code is invoked via Azure Function or FastAPI ^[1].

@eyurtsev requesting your help on this. I am unable to figure of the working of this.

[rvasa779]

Hi @eyurtsev , @dosu,

I have downgraded few dependency for it to work:

googleapis-common-protos==1.56.2
protobuf==3.20.3

The latest versions are not working.

Thanks, worked out for me aswell. as I encountered the same problem today.

any updates on this

[dan-wit]

Do you happen to have any updates on this matter?

[sumeetattree]

This seems to be happening when a tool call is hallucinated by the gemini models. This is the output that I am seeing from the langchain_google_vertexai/_utils.py [See this] (https://github.com/langchain-ai/langchain-google/blob/main/libs/vertexai/langchain_google_vertexai/_utils.py#L172)

get_generation_info: <class 'google.cloud.aiplatform_v1beta1.types.content.Candidate'>; finish_reason: 15
finish_message: "Unexpected tool call: print(weather.get_current_weather(place=\'Bern\'))"

finish_reason here is returned as 15 which fails when we try to access .name on it as it is not part of the FinishReason enum.

This is explained here and here. These seem to be the part of the REST api. Are the python apis out of date?

Can we in the meantime have a fix out from langchain side so it does not throw AttributeError?

[sumeetattree]

Looks like this has an attempted fix here
