Stefano Lottini	19c68c7652	FEATURE: Astra DB, LLM cache classes (exact-match and semantic cache) (#13834 ) This PR provides idiomatic implementations for the exact-match and the semantic LLM caches using Astra DB as backend through the database's HTTP JSON API. These caches require the `astrapy` library as dependency. Comes with integration tests and example usage in the `llm_cache.ipynb` in the docs. @baskaryan this is the Astra DB counterpart for the Cassandra classes you merged some time ago, tagging you for your familiarity with the topic.

Stefano Lottini	272df9dcae	Astra DB, chat message history (#13836 ) This PR adds a chat message history component that uses Astra DB for persistence through the JSON API. The `astrapy` package is required for this class to work. I have added tests and a small notebook, and updated the relevant references in the other docs pages. (@rlancemartin this is the counterpart of the Cassandra equivalent class you so helpfully reviewed back at the end of June) Thank you!	10 months ago

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

Leonid Ganeline	1d2981114f	DOCS updated `async-faiss` example (#13434 ) The original notebook has the `faiss` title which is duplicated in the`faiss.jpynb`. As a result, we have two `faiss` items in the vectorstore ToC. And the first item breaks the searching order (it is placed between `A...` items). - I updated title to `Asynchronous Faiss`.	10 months ago
Leonid Ganeline	9ff8f69e75	DOCS updated `memory` Titles (#13435 ) - Fixed titles for two notebooks. They were inconsistent with other titles and clogged ToC. - Added `Upstash` description and link - Moved the authentication text up in the `Elasticsearch` nb, right after package installation. It was on the end of the page which was a wrong place.	10 months ago
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. It created an ugly ToC element as `Activeloop DeepLake's DeepMemory + LangChain + ragas or how to get +27% on RAG recall.` - Added Activeloop description - improved consistency in text - fixed ToC (it was using HTML tagas that break left-side in-page ToC).

Predrag Gruevski	2ebd167dba	Lint Python notebooks with ruff. (#12677 ) The new ruff version fixed the blocking bugs, and I was able to fairly easily us to a passing state: ruff fixed some issues on its own, I fixed a handful by hand, and I added a list of narrowly-targeted exclusions for files that are currently failing ruff rules that we probably should look into eventually. I went pretty lenient on the docs / cookbooks rules, allowing dead code and such things. Perhaps in the future we may want to tighten the rules further, but this is already a good set of checks that found real issues and will prevent them going forward.	10 months ago

mertkayhan	9b4974871d	IMPROVEMENT Increase flexibility of ElasticVectorSearch (#6863 ) Hey @rlancemartin, @eyurtsev , I did some minimal changes to the `ElasticVectorSearch` client so that it plays better with existing ES indices. Main changes are as follows: 1. You can pass the dense vector field name into `_default_script_query` 2. You can pass a custom script query implementation and the respective parameters to `similarity_search_with_score` 3. You can pass functions for building page content and metadata for the resulting `Document` <!-- Thank you for contributing to LangChain!
