ChatHuggingFace does not implement `bind_tools`

Travis-Barton commented 4 months ago

Checked other resources

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

Example Code

from langchain_community.llms import HuggingFaceEndpoint from langchain_community.chat_models import ChatHuggingFace llm = HuggingFaceEndpoint( repo_id="meta-llama/Meta-Llama-3-8B-Instruct", task="text-generation", max_new_tokens=1000, top_k=30, temperature=0.1, repetition_penalty=1.03, huggingfacehub_api_token=get_secrets()['llm_api_keys']['HUGGINGFACE_API_TOKEN'], ) return ChatHuggingFace(llm=llm)

Error Message and Stack Trace (if applicable)

Traceback (most recent call last): File "/Applications/PyCharm.app/Contents/plugins/python/helpers/pydev/pydevconsole.py", line 364, in runcode coro = func() File "", line 15, in File "/Users/travisbarton/opt/anaconda3/envs/TriviaGPT_dashboards_and_cloud_functions/lib/python3.10/site-packages/langchain_core/language_models/chat_models.py", line 912, in bind_tools raise NotImplementedError() NotImplementedError

Description

But this doesn't leave us any way to use this chat model and return a structured output. It also breaks our back-end which requires that the model be in a ChatModel format. Is there any plan to update this?

I have the same error:

I think this has been solved. Try updating it to the latest version
