Josep Pon Farreny	143049c90f	Added partial_variables to BaseStringMessagePromptTemplate.from_template(...) (#13645 ) Description: BaseStringMessagePromptTemplate.from_template was passing the value of partial_variables into cls(...) via *kwargs, rather than passing it to PromptTemplate.from_template. Which resulted in those partial_variables being* lost and becoming required input_variables.

Taqi Jaffri	d65c36d60a	docugami cookbook (#13183 ) Adds a cookbook for semi-structured RAG via Docugami. This follows the same outline as the semi-structured RAG with Unstructured cookbook: https://github.com/langchain-ai/langchain/blob/master/cookbook/Semi_Structured_RAG.ipynb The main change is this cookbook uses Docugami instead of Unstructured to find text and tables, and shows how XML markup in the output helps with retrieval and generation.

Stijn Tratsaert	b6f70d776b	VertexAI LLM count_tokens method requires list of prompts (#13451 ) I encountered this during summarization with VertexAI. I was receiving an INVALID_ARGUMENT error, as it was trying to send a list of about 17000 single characters. The [count_tokens method](https://github.com/googleapis/python-aiplatform/blob/main/vertexai/language_models/_language_models.py#L658) made available by Google takes in a list of prompts. It does not fail for small texts, but it does for longer documents because the argument list will be exceeding Googles allowed limit. Enforcing the list type makes it work successfully. This change will cast the input text to count to a list of that single text so that the input format is always correct. [Twitter](https://www.x.com/stijn_tratsaert)	10 months ago
Wang Wei	fe7b40cb2a	feat: add ERNIE-Bot-4 Function Calling (#13320 ) - Description: ERNIE-Bot-Chat-4 Large Language Model adds the ability of `Function Calling` by passing parameters through the `functions` parameter in the request. To simplify function calling for ERNIE-Bot-Chat-4, the `create_ernie_fn_chain()` function has been added. The definition and usage of the `create_ernie_fn_chain()` function is similar to that of the `create_openai_fn_chain()` function. Examples as the follows: ``` import json from langchain.chains.ernie_functions import ( create_ernie_fn_chain, ) from langchain.chat_models import ErnieBotChat from langchain.prompts import ChatPromptTemplate def get_current_news(location: str) -> str: """Get the current news based on the location.' Args: location (str): The location to query. Returs: str: Current news based on the location. """ news_info = { "location": location, "news": [ "I have a Book.", "It's a nice day, today." ] } return json.dumps(news_info) def get_current_weather(location: str, unit: str="celsius") -> str: """Get the current weather in a given location Args: location (str): location of the weather. unit (str): unit of the tempuature. Returns: str: weather in the given location. """ weather_info = { "location": location, "temperature": "27", "unit": unit, "forecast": ["sunny", "windy"], } return json.dumps(weather_info) llm = ErnieBotChat(model_name="ERNIE-Bot-4") prompt = ChatPromptTemplate.from_messages( [ ("human", "{query}"), ] ) chain = create_ernie_fn_chain([get_current_weather, get_current_news], llm, prompt, verbose=True) res = chain.run("北京今天的新闻是什么？") print(res) ``` The running results of the above program are shown below： ``` > Entering new LLMChain chain... Prompt after formatting: Human: 北京今天的新闻是什么？ > Finished chain. {'name': 'get_current_news', 'thoughts': '用户想要知道北京今天的新闻。我可以使用get_current_news工具来获取这些信息。', 'arguments': {'location': '北京'}} ```	10 months ago
