Martin Krasser	79ed66f870	EXPERIMENTAL Generic LLM wrapper to support chat model interface with configurable chat prompt format (#8295 ) ## Update 2023-09-08 This PR now supports further models in addition to Lllama-2 chat models. See [this comment](#issuecomment-1668988543) for further details. The title of this PR has been updated accordingly. ## Original PR description This PR adds a generic `Llama2Chat` model, a wrapper for LLMs able to serve Llama-2 chat models (like `LlamaCPP`, `HuggingFaceTextGenInference`, ...). It implements `BaseChatModel`, converts a list of chat messages into the [required Llama-2 chat prompt format](https://huggingface.co/blog/llama2#how-to-prompt-llama-2) and forwards the formatted prompt as `str` to the wrapped `LLM`. Usage example: ```python # uses a locally hosted Llama2 chat model llm = HuggingFaceTextGenInference( inference_server_url="http://127.0.0.1:8080/", max_new_tokens=512, top_k=50, temperature=0.1, repetition_penalty=1.03, ) # Wrap llm to support Llama2 chat prompt format. # Resulting model is a chat model model = Llama2Chat(llm=llm) messages = [ SystemMessage(content="You are a helpful assistant."), MessagesPlaceholder(variable_name="chat_history"), HumanMessagePromptTemplate.from_template("{text}"), ] prompt = ChatPromptTemplate.from_messages(messages) memory = ConversationBufferMemory(memory_key="chat_history", return_messages=True) chain = LLMChain(llm=model, prompt=prompt, memory=memory) # use chat model in a conversation # ... ``` Also part of this PR are tests and a demo notebook. - Tag maintainer: @hwchase17 - Twitter handle: `@mrt1nz` --------- Co-authored-by: Erick Friis <erick@langchain.dev>	10 months ago

Piyush Jain	d2335d0114	IMPROVEMENT Neptune graph updates (#13491 ) ## Description This PR adds an option to allow unsigned requests to the Neptune database when using the `NeptuneGraph` class. ```python graph = NeptuneGraph( host='<my-cluster>', port=8182, sign=False ) ``` Also, added is an option in the `NeptuneOpenCypherQAChain` to provide additional domain instructions to the graph query generation prompt. This will be injected in the prompt as-is, so you should include any provider specific tags, for example `<instructions>` or `<INSTR>`. ```python chain = NeptuneOpenCypherQAChain.from_llm( llm=llm, graph=graph, extra_instructions=""" Follow these instructions to build the query: 1. Countries contain airports, not the other way around 2. Use the airport code for identifying airports """ ) ```	10 months ago

Leonid Ganeline	1d2981114f	DOCS updated `async-faiss` example (#13434 ) The original notebook has the `faiss` title which is duplicated in the`faiss.jpynb`.

Stefano Lottini	b029d9f4e6	Astra DB: minor improvements to docstrings and demo notebook (#13449 ) This PR brings a few minor improvements to the docs, namely class/method docstrings and the demo notebook. - A note on how to control concurrency levels to tune performance in bulk inserts, both in the class docstring and the demo notebook; - Slightly increased concurrency defaults after careful experimentation (still on the conservative side even for clients running on less-than-typical network/hardware specs) - renamed the DB token variable to the standardized `ASTRA_DB_APPLICATION_TOKEN` name (used elsewhere, e.g. in the Astra DB docs) - added a note and a reference (add_text docstring, demo notebook) on allowed metadata field names. Thank you!	10 months ago

Leonid Ganeline	283ef1f66d	DOCS fix for `integratons/document_loaders` sidebar (#13471 ) The current `integrations/document_loaders/` sidebar has the `example_data` item, which is a menu with a single item: "Notebook". It is happening because the `integrations/document_loaders/` folder has the `example_data/notebook.md` file that is used to autogenerate the above menu item. - removed an example_data/notebook.md file. Docusaurus doesn't have simple ways to fix this problem (to exclude folders/files from an autogenerated sidebar). Removing this file didn't break any existing examples, so this fix is safe.	10 months ago

Leonid Ganeline	17c2007e0c	DOCS updated `Activeloop DeepMemory` notebook (#13428 ) - Fixed the title of the notebook.
