Checked other resources

• I added a very descriptive title to this issue.
• I searched the LangChain documentation with the integrated search.
• I used the GitHub search to find a similar question and didn't find it.
• I am sure that this is a bug in LangChain rather than my code.
• The bug is not resolved by updating to the latest stable version of LangChain (or the specific integration package).

Example Code

from langchain.prompts import PromptTemplate
from langchain_community.llms.huggingface_endpoint import HuggingFaceEndpoint
from langchain.chains import LLMChain

llm = HuggingFaceEndpoint(
repo_id="google/flan-t5-large",
temperature=0,
max_new_tokens=250,
huggingfacehub_api_token=HUGGINGFACE_TOKEN
)

prompt_tpl = PromptTemplate(
template="What is the good name for a company that makes {product}",
input_variables=["product"]
)

chain = LLMChain(llm=llm, prompt=prompt_tpl)
print(chain.invoke("colorful socks"))

Description

Hi, folks. I'm just trying to run a simple LLMChain and getting the Bad Request due to model_kwargs checking. I found there are several same issue being raised, however it haven't fixed in the latest release of langchain. Please help to take a look, thanks!

I'm facing the same problem (with various other models as well). I believe it could be caused by this commit on the huggingface_endpoint.py file. There's a new definition for _default_params that expects a base set of params for text-generation tasks. I'm guessing that if the model doesn't include those params - besides it throwing an error for models of different task types - it fails with the error you received.
I could be wrong, but that's where I'm at with my research on this issue.

[nicole-wright]

I downgraded my requirements on the langchain library for now, and I can use the endpoint class. It's just a workaround, but for reference, I'm using Python 3.11, and I've pinned the following package versions:

langchain==0.1.6
langchain-cli==0.0.21
langchain-openai==0.0.6
huggingface_hub==0.21.4
python-dotenv==1.0.0
pydantic==1.10.13

hf_model_id = "facebook/bart-large-cnn"
hf_endpoint_url = f"https://api-inference.huggingface.co/models/{hf_model_id}"

llm = HuggingFaceEndpoint(
    task="summarization",
    endpoint_url=hf_endpoint_url,
)

[jamesnixon-aws]

I am also facing this issue, and it appears that @nicole-wright is correct. It is specifically these lines: https://github.com/langchain-ai/langchain/blob/master/libs/community/langchain_community/llms/huggingface_endpoint.py#L199-L215 which inject default params into the call to the HuggingFace API regardless of whether they are present on the HuggingFaceEndpoint instance or not.

If a model/endpoint does not support these, it causes HuggingFace to throw back an error (even if the params are populated as None, e.g. {"stop_sequences": None}).

Perhaps a simple fix would be to remove None values from the invocation_params prior to posting to the client.

[Laatcha]

This is happening also when using local models.
I'm trying the chain with local HuggingFace model "t5-flan"

I got errors of type:
The followingmodel_kwargs are not used by the model: ['return_full_text'] (note: typos in the generate arguments will also show up in this list)

llm = HuggingFacePipeline.from_model_id(model_id=flan, task="text2text-generation", model_kwargs={"temperature":1e-10
                                                                                                #    ,"return_full_text":False
                                                                                                   }, device=0)
template = PromptTemplate(input_variables=["input"], template="{input}")
chain = LLMChain(llm=llm, verbose=True, prompt=template)
chain("Say something?")

However, this is working when using local Huggingface gpt2 with "text-generation"

[dongkyunlim77]

Did anyone solve this issue?

[nicole-wright]

I'm fairly sure it's a bug and it needs a PR. I'm not sure I know the library enough to contribute but I could always give it a shot. For the prototyping I'm doing, downgrading to a previous release works and I can still access both the hub and the pipeline objects correctly.

[AccentureGabriv93]

I agree I also see the problem with various model as microsoft/phi-1_5
I hope for a fast bug fixing

I am trying to download the langchain-text-splitters library, but it is not suitable with these set of libraries, so I needed to upgrade the langchain library (but the main error kwargs shows again).
Is there any help?? this is urgent please.

[NotShrirang]

I have environment like

huggingface-hub==0.22.2

langchain-core==0.1.42

pipeline = HuggingFaceEndpoint(
        huggingfacehub_api_token=os.getenv("HUGGINGFACE_API_KEY"),
        repo_id="facebook/bart-large-cnn"

result = pipe.invoke(doc.page_content)

I tried downgrading the langchain library, but it is causing issues with other packages (langchain-community etc.). What can I do?

Solution: Using HuggingFaceHub with LangChain

I found an effective way to use the HuggingFaceHub model with LangChain. Instead of the previous method, we can simplify and enhance the configuration as follows:

Previous Method

from langchain_huggingface.llms import HuggingFaceEndpoint 

llm = HuggingFaceEndpoint(
    repo_id="google/flan-t5-large",
    temperature=0,
    max_new_tokens=250,
    huggingfacehub_api_token=HUGGINGFACE_API_TOKEN
)

Improved Method

This new method utilizes the HuggingFaceHub from LangChain with more detailed model configurations.

from langchain import HuggingFaceHub

llm = HuggingFaceHub(
    repo_id='google/flan-t5-base',
    model_kwargs={"temperature":0, "max_length":180, 'max_new_tokens' : 120, 'top_k' : 10, 'top_p': 0.95, 'repetition_penalty':1.03}
)

# using the model 
output = llm.invoke('Can you tell me the capital of russia')

print(output)

[olk]

@aymeric-roucher , @baskaryan - could provide a bug fix please, your commit 0d29476 breaks LangChain (see bug report above)!

[dordonezc]

Hey, I'm also getting the same issue as mentioned above. I tried downgrading the packages with no success is there any other workaround?

[jodyhuntatx]

Same problem here, reverted back to HuggingFaceHub and enduring the deprecation warnings. Hopefully the bug gets fixed before the workaround is unsupported.
