Shuqian	ee1d488c03	fix: rename the invalid function name of GoogleSerperResults Tool for OpenAIFunctionCall (#7176 ) - Description: rename the invalid function name of GoogleSerperResults Tool for OpenAIFunctionCall - Tag maintainer: @hinthornw When I use the GoogleSerperResults in OpenAIFunctionCall agent, the following error occurs: ```shell openai.error.InvalidRequestError: 'Google Serrper Results JSON' does not match '^[a-zA-Z0-9_-]{1,64}$' - 'functions.0.name' ``` So I rename the GoogleSerperResults's property "name" from "Google Serrper Results JSON" to "google_serrper_results_json" just like GoogleSerperRun's name: "google_serper", and it works. I guess this should be reasonable.	1 year ago

Simon Cheung	81eebc4070	Add HugeGraphQAChain to support gremlin generating chain (#7132 ) [Apache HugeGraph](https://github.com/apache/incubator-hugegraph) is a convenient, efficient, and adaptable graph database, compatible with the Apache TinkerPop3 framework and the Gremlin query language. In this PR, the HugeGraph and HugeGraphQAChain provide the same functionality as the existing integration with Neo4j and enables query generation and question answering over HugeGraph database. The difference is that the graph query language supported by HugeGraph is not cypher but another very popular graph query language [Gremlin](https://tinkerpop.apache.org/gremlin.html). A notebook example and a simple test case have also been added. --------- Co-authored-by: Bagatur <baskaryan@gmail.com>	1 year ago

It now uses `max_tokens`, so I set this. And I also set other defaults used in GPT4All client [here](https://github.com/nomic-ai/gpt4all/blob/main/gpt4all-bindings/python/gpt4all/gpt4all.py). Confirm it now works: ``` $ from langchain.llms import GPT4All $ model = GPT4All(model=local_path) $ model("The capital of France is ", max_tokens=10) < Model logging > "....Paris." ``` --------- Co-authored-by: R.

Nicolas	490fcf9d98	docs: New experimental UI for Mendable Search (#6558 ) This PR introduces a new Mendable UI tailored to a better search experience. We're more closely integrating our traditional search with our AI generation. With this change, you won't have to tab back and forth between the mendable bot and the keyword search. Both types of search are handled in the same bar. This should make the docs easier to navigate. while still letting users get code generations or AI-summarized answers if they so wish. Also, it should reduce the cost. Would love to hear your feedback :) Cc: @dev2049 @hwchase17	1 year ago

Mike Salvatore	d0c7f7c317	Remove `None` default value for FAISS relevance_score_fn (#7085 ) ## Description The type hint for `FAISS.__init__()`'s `relevance_score_fn` parameter allowed the parameter to be set to `None`. However, a default function is provided by the constructor. This led to an unnecessary check in the code, as well as a test to verify this check.
