Sergey Kozlov	135cb86215	Fix QuestionListOutputParser (#9738 ) This PR fixes `QuestionListOutputParser` text splitting. `QuestionListOutputParser` incorrectly splits numbered list text into lines. If text doesn't end with `\n` , the regex doesn't capture the last item. So it always returns `n - 1` items, and `WebResearchRetriever.llm_chain` generates less queries than requested in the search prompt. How to reproduce: ```python from langchain.retrievers.web_research import QuestionListOutputParser parser = QuestionListOutputParser() good = parser.parse( """1. This is line one. 2. This is line two. """ # <-- ! ) bad = parser.parse( """1. This is line one. 2. This is line two.""" # <-- No new line. ) assert good.lines == ['1. This is line one.\n', '2. This is line two.\n'], good.lines assert bad.lines == ['1. This is line one.\n', '2. This is line two.'], bad.lines ``` NOTE: Last item will not contain a line break but this seems ok because the items are stripped in the `WebResearchRetriever.clean_search_query()`.	1 year ago

And if you are below you get 3.4 "pyspark is not installed. Please install it with pip nstall pyspark" which is not helpful. Also if you not have pyspark installed you get already the error in init.

Margaret Qian	30151c99c7	Update Mosaic endpoint input/output api (#7391 ) As noted in prior PRs (https://github.com/hwchase17/langchain/pull/6060, https://github.com/hwchase17/langchain/pull/7348), the input/output format has changed a few times as we've stabilized our inference API. This PR updates the API to the latest stable version as indicated in our docs: https://docs.mosaicml.com/en/latest/inference.html The input format looks like this: `{"inputs": [<prompt>]} ` The output format looks like this: ` {"outputs": [<output_text>]} ` --------- Co-authored-by: Bagatur <baskaryan@gmail.com>	1 year ago

Tudor Golubenco	dc30edf51c	Xata as a chat message memory store (#9719 ) This adds Xata as a memory store also to the python version of LangChain, similar to the [one for LangChain.js](https://github.com/hwchase17/langchainjs/pull/2217). I have added a Jupyter Notebook with a simple and a more complex example using an agent. To run the integration test, you need to execute something like: ``` XATA_API_KEY='xau_...' XATA_DB_URL="https://demo-uni3q8.eu-west-1.xata.sh/db/langchain" poetry run pytest tests/integration_tests/memory/test_xata.py ``` Where `langchain` is the database you create in Xata.	1 year ago
William FH	dff00ea91e	Chat Loaders (#9708 ) Still working out interface/notebooks + need discord data dump to test out things other than copy+paste Update: - Going to remove the 'user_id' arg in the loaders themselves and just standardize on putting the "sender" arg in the extra kwargs. Then can provide a utility function to map these to ai and human messages - Going to move the discord one into just a notebook since I don't have a good dump to test on and copy+paste maybe isn't the greatest thing to support in v0 - Need to do more testing on slack since it seems the dump only includes channels and NOT 1 on 1 convos - --------- Co-authored-by: Harrison Chase <hw.chase.17@gmail.com>	1 year ago

Tomaz Bratanic	dacf96895a	Add the option to use separate LLMs for GraphCypherQA chain (#9689 ) The Graph Chains are different in the way that it uses two LLMChains instead of one like the retrievalQA chains. Therefore, sometimes you want to use different LLM to generate the database query and to generate the final answer. This feature would make it more convenient to use different LLMs in the same chain. I have also renamed the Graph DB QA Chain to Neo4j DB QA Chain in the documentation only as it is used only for Neo4j. The naming was ambigious as it was the first graphQA chain added and wasn't sure how do you want to spin it.	1 year ago

Leonid Ganeline	cf792891f1	📖 docs: compact api reference (#8651 ) Updated design of the "API Reference" text Here is an example of the current format: ![image](https://github.com/langchain-ai/langchain/assets/2256422/8727f2ba-1b69-497f-aa07-07f939b6da3b) It changed to `langchain.retrievers.ElasticSearchBM25Retriever` format. The same format as it is in the API Reference Toc. It also resembles code: `from langchain.retrievers import ElasticSearchBM25Retriever` (namespace THEN class_name) Current format is `ElasticSearchBM25Retriever from langchain.retrievers` (class_name THEN namespace) This change is in line with other formats and improves readability. @baskaryan	1 year ago

Leonid Ganeline	b048236c1a	📖 docs: `integrations/agent_toolkits` (#9333 ) Note: There are no changes in the file names! - The group name on the main navbar changed: `Agent toolkits` -> `Agents & Toolkits`. Examples here are the mix of the Agent and Toolkit examples because Agents and Toolkits in examples are always used together. - Titles changed: removed "Agent" and "Toolkit" suffixes. The reason is the same. - Formatting: mostly cleaning the header structure, so it could be better on the right-side navbar. Main navbar is looking much cleaner now.	1 year ago

Patrick Loeber	5990651070	Add new document_loader: AssemblyAIAudioTranscriptLoader (#9667 ) This PR adds a new document loader `AssemblyAIAudioTranscriptLoader` that allows to transcribe audio files with the [AssemblyAI API](https://www.assemblyai.com) and loads the transcribed text into documents. - Add new document_loader with class `AssemblyAIAudioTranscriptLoader` - Add optional dependency `assemblyai` - Add unit tests (using a Mock client) - Add docs notebook This is the equivalent to the JS integration already available in LangChain.js. See the [LangChain JS docs AssemblyAI page](https://js.langchain.com/docs/modules/data_connection/document_loaders/integrations/web_loaders/assemblyai_audio_transcription). At its simplest, you can use the loader to get a transcript back from an audio file like this: ```python from langchain.document_loaders.assemblyai import AssemblyAIAudioTranscriptLoader loader = AssemblyAIAudioTranscriptLoader(file_path="./testfile.mp3") docs = loader.load() ``` To use it, it needs the `assemblyai` python package installed, and the environment variable `ASSEMBLYAI_API_KEY` set with your API key. Alternatively, the API key can also be passed as an argument.

Eugene Yurtsev	b88dfcb42a	Add indexing support (#9614 ) This PR introduces a persistence layer to help with indexing workflows into vectostores. The indexing code helps users to: 1. Avoid writing duplicated content into the vectostore 2. Avoid over-writing content if it's unchanged Importantly, this keeps on working even if the content being written is derived via a set of transformations from some source content (e.g., indexing children documents that were derived from parent documents by chunking.) The two main components are: 1. Persistence layer that keeps track of which keys were updated and when. Keeping track of the timestamp of updates, allows to clean up old content safely, and with minimal complexity. 2. HashedDocument which is used to hash the contents (including metadata) of the documents. We rely on the hashes for identifying duplicates. The indexing code works with ANY document loader. To add transformations to the documents, users for now can add a custom document loader that composes an existing loader together with document transformers. --------- Co-authored-by: Bagatur <baskaryan@gmail.com>	1 year ago
