Akio Nishimura	785b9d47b7	Fix stop key of TextGen. (#11109 ) The key of stopping strings used in text-generation-webui api is [`stopping_strings`](https://github.com/oobabooga/text-generation-webui/blob/main/api-examples/api-example.py#L51), not `stop`. <!-- Thank you for contributing to LangChain!

Nuno Campos	cfa2203c62	Add input/output schemas to runnables (#11063 ) This adds `input_schema` and `output_schema` properties to all runnables, which are Pydantic models for the input and output types respectively. These are inferred from the structure of the Runnable as much as possible, the only manual typing needed is - optionally add type hints to lambdas (which get translated to input/output schemas) - optionally add type hint to RunnablePassthrough These schemas can then be used to create JSON Schema descriptions of input and output types, see the tests - [x] Ensure no InputType and OutputType in our classes use abstract base classes (replace with union of subclasses) - [x] Implement in BaseChain and LLMChain - [x] Implement in RunnableBranch - [x] Implement in RunnableBinding, RunnableMap, RunnablePassthrough, RunnableEach, RunnableRouter - [x] Implement in LLM, Prompt, Chat Model, Output Parser, Retriever - [x] Implement in RunnableLambda from function signature - [x] Implement in Tool <!-- Thank you for contributing to LangChain!

A simpler prompt have seemed to work better for generating cypher queries in our testing. Note: This version will require boto3 version 1.28.38 or greater to work.	11 months ago
Douglas Monsky	d5f1969d55	Introducing Enhanced Functionality to WeaviateHybridSearchRetriever: Accepting Additional Keyword Arguments (#10802 ) Description: This commit enriches the `WeaviateHybridSearchRetriever` class by introducing a new parameter, `hybrid_search_kwargs`, within the `_get_relevant_documents` method. This parameter accommodates arbitrary keyword arguments (`kwargs`) which can be channeled to the inherited public method, `get_relevant_documents`, originating from the `BaseRetriever` class. This modification facilitates more intricate querying capabilities, allowing users to convey supplementary arguments to the `.with_hybrid()` method. This expansion not only makes it possible to perform a more nuanced search targeting specific properties but also grants the ability to boost the weight of searched properties, to carry out a search with a custom vector, and to apply the Fusion ranking method. The documentation has been updated accordingly to delineate these new possibilities in detail. In light of the layered approach in which this search operates, initiating with `query.get()` and then transitioning to `.with_hybrid()`, several advantageous opportunities are unlocked for the hybrid component that were previously unattainable. Here’s a representative example showcasing a query structure that was formerly unfeasible: [Specific Properties Only](https://weaviate.io/developers/weaviate/search/hybrid#selected-properties-only) "The example below illustrates a BM25 search targeting the keyword 'food' exclusively within the 'question' property, integrated with vector search results corresponding to 'food'." ```python response = ( client.query .get("JeopardyQuestion", ["question", "answer"]) .with_hybrid( query="food", properties=["question"], # Will now be possible moving forward alpha=0.25 ) .with_limit(3) .do() ) ``` This functionality is now accessible through my alterations, by conveying `hybrid_search_kwargs={"properties": ["question", "answer"]}` as an argument to `WeaviateHybridSearchRetriever.get_relevant_documents()`. For example: ```python import os from weaviate import Client from langchain.retrievers import WeaviateHybridSearchRetriever client = Client( url=os.getenv("WEAVIATE_CLIENT_URL"), additional_headers={ "X-OpenAI-Api-Key": os.getenv("OPENAI_API_KEY"), "Authorization": f"Bearer {os.getenv('WEAVIATE_API_KEY')}", }, ) index_name = "Document" text_key = "content" attributes = ["title", "summary", "header", "url"] retriever = ExtendedWeaviateHybridSearchRetriever( client=client, index_name=index_name, text_key=text_key, attributes=attributes, ) # Warning: to utilize properties in this way, each use property must also be in the list `attributes + [text_key]`. hybrid_search_kwargs = {"properties": ["summary^2", "content"]} query_text = "Some Query Text" relevant_docs = retriever.get_relevant_documents( query=query_text, hybrid_search_kwargs=hybrid_search_kwargs ) ``` In my experience working with the `weaviate-client` library, I have found that these supplementary options stand as vital tools for refining/finetuning searches, notably within multifaceted datasets. As a final note, this implementation supports both backwards and forward (within reason) compatiblity. It accommodates any future additional parameters Weaviate may add to `.with_hybrid()`, without necessitating further alterations.

Stefano Lottini	49b65a1b57	CassandraCache and CassandraSemanticCache can handle any "Generation" (#10563 ) Hello, this PR improves coverage for caching by the two Cassandra-related caches (i.e. exact-match and semantic alike) by switching to the more general `dumps`/`loads` serdes utilities. This enables cache usage within e.g. `ChatOpenAI` contexts (which need to store lists of `ChatGeneration` instead of `Generation`s), which was not possible as long as the cache classes were relying on the legacy `_dump_generations_to_json` and `_load_generations_from_json`). Additionally, a slightly different init signature is introduced for the cache objects: - named parameters required for init, to pave the way for easier changes in the future connect-to-db flow (and tests adjusted accordingly) - added a `skip_provisioning` optional passthrough parameter for use cases where the user knows the underlying DB table, etc already exist.

Stefano Lottini	415d38ae62	Cassandra Vector Store, add metadata filtering + improvements (#9280 ) This PR addresses a few minor issues with the Cassandra vector store implementation and extends the store to support Metadata search. Thanks to the latest cassIO library (>=0.1.0), metadata filtering is available in the store. Further, - the "relevance" score is prevented from being flipped in the [0,1] interval, thus ensuring that 1 corresponds to the closest vector (this is related to how the underlying cassIO class returns the cosine difference); - bumped the cassIO package version both in the notebooks and the pyproject.toml; - adjusted the textfile location for the vector-store example after the reshuffling of the Langchain repo dir structure; - added demonstration of metadata filtering in the Cassandra vector store notebook; - better docstring for the Cassandra vector store class; - fixed test flakiness and removed offending out-of-place escape chars from a test module docstring; To my knowledge all relevant tests pass and mypy+black+ruff don't complain.

berkedilekoglu	73b9ca54cb	Using batches for update document with a new function in ChromaDB (#6561 ) `2a4b32dee2/langchain/vectorstores/chroma.py (L355-L375)` Currently, the defined update_document function only takes a single document and its ID for updating. However, Chroma can update multiple documents by taking a list of IDs and documents for batch updates. If we update 'update_document' function both document_id and document can be `Union[str, List[str]]` but we need to do type check. Because embed_documents and update functions takes List for text and document_ids variables. I believe that, writing a new function is the best option. I update the Chroma vectorstore with refreshed information from my website every 20 minutes. Updating the update_document function to perform simultaneous updates for each changed piece of information would significantly reduce the update time in such use cases. For my case I update a total of 8810 chunks. Updating these 8810 individual chunks using the current function takes a total of 8.5 minutes. However, if we process the inputs in batches and update them collectively, all 8810 separate chunks can be updated in just 1 minute. This significantly reduces the time it takes for users of actively used chatbots to access up-to-date information. I can add an integration test and an example for the documentation for the new update_document_batch function. @hwchase17 [berkedilekoglu](https://twitter.com/berkedilekoglu)	11 months ago

Screenshot below illustrates the problem: <img width="1917" alt="image" src="https://github.com/langchain-ai/langchain/assets/749277/d28c27cc-40fb-4258-8710-844c00d3c2b0"> As you can see, the new replicate_weights param is being sent down with x-order = 0 (which is causing langchain to use that param instead of prompt which is x-order = 1) FYI @baskaryan this requires a fix otherwise replicate is broken for these models. I have pinged replicate whether they want to fix it on their end by changing the x-order returned by them. Update: per suggestion I updated the PR to just allow manually setting the prompt_key which can be set to "prompt" in this case by callers... I think this is going to be faster anyway than trying to dynamically query the model every time if you know the prompt key for your model. --------- Co-authored-by: Taqi Jaffri <tjaffri@docugami.com>	11 months ago

Michael Haddad	c6b27b3692	add konko chat_model files (#10267 ) _Thank you to the LangChain team for the great project and in advance for your review. Let me know if I can provide any other additional information or do things differently in the future to make your lives easier 🙏 _ @hwchase17 please let me know if you're not the right person to review 😄 This PR enables LangChain to access the Konko API via the chat_models API wrapper. Konko API is a fully managed API designed to help application developers: 1. Select the right LLM(s) for their application 2. Prototype with various open-source and proprietary LLMs 3. Move to production in-line with their security, privacy, throughput, latency SLAs without infrastructure set-up or administration using Konko AI's SOC 2 compliant infrastructure _Note on integration tests:_ We added 14 integration tests. They will all fail unless you export the right API keys. 13 will pass with a KONKO_API_KEY provided and the other one will pass with a OPENAI_API_KEY provided. When both are provided, all 14 integration tests pass. If you would like to test this yourself, please let me know and I can provide some temporary keys. ### Installation and Setup 1. First you'll need an API key 2. Install Konko AI's Python SDK 1. Enable a Python3.8+ environment `pip install konko` 3. Set API Keys Option 1: Set Environment Variables You can set environment variables for 1. KONKO_API_KEY (Required) 2. OPENAI_API_KEY (Optional) In your current shell session, use the export command: `export KONKO_API_KEY={your_KONKO_API_KEY_here}` `export OPENAI_API_KEY={your_OPENAI_API_KEY_here} #Optional` Alternatively, you can add the above lines directly to your shell startup script (such as .bashrc or .bash_profile for Bash shell and .zshrc for Zsh shell) to have them set automatically every time a new shell session starts. Option 2: Set API Keys Programmatically If you prefer to set your API keys directly within your Python script or Jupyter notebook, you can use the following commands: ```python konko.set_api_key('your_KONKO_API_KEY_here') konko.set_openai_api_key('your_OPENAI_API_KEY_here') # Optional ``` ### Calling a model Find a model on the [[Konko Introduction page](https://docs.konko.ai/docs#available-models)](https://docs.konko.ai/docs#available-models) For example, for this [[LLama 2 model](https://docs.konko.ai/docs/meta-llama-2-13b-chat)](https://docs.konko.ai/docs/meta-llama-2-13b-chat). The model id would be: `"meta-llama/Llama-2-13b-chat-hf"` Another way to find the list of models running on the Konko instance is through this [[endpoint](https://docs.konko.ai/reference/listmodels)](https://docs.konko.ai/reference/listmodels). From here, we can initialize our model: ```python chat_instance = ChatKonko(max_tokens=10, model = 'meta-llama/Llama-2-13b-chat-hf') ``` And run it: ```python msg = HumanMessage(content="Hi") chat_response = chat_instance([msg]) ```	12 months ago

maks-operlejn-ds	274c3dc3a8	Multilingual anonymization (#10327 ) ### Description Add multiple language support to Anonymizer PII detection in Microsoft Presidio relies on several components - in addition to the usual pattern matching (e.g. using regex), the analyser uses a model for Named Entity Recognition (NER) to extract entities such as: - `PERSON` - `LOCATION` - `DATE_TIME` - `NRP` - `ORGANIZATION` [[Source]](https://github.com/microsoft/presidio/blob/main/presidio-analyzer/presidio_analyzer/predefined_recognizers/spacy_recognizer.py) To handle NER in specific languages, we utilize unique models from the `spaCy` library, recognized for its extensive selection covering multiple languages and sizes. However, it's not restrictive, allowing for integration of alternative frameworks such as [Stanza](https://microsoft.github.io/presidio/analyzer/nlp_engines/spacy_stanza/) or [transformers](https://microsoft.github.io/presidio/analyzer/nlp_engines/transformers/) when necessary. ### Future works - automatic language detection - instead of passing the language as a parameter in `anonymizer.anonymize`, we could detect the language/s beforehand and then use the corresponding NER model. We have discussed this internally and @mateusz-wosinski-ds will look into a standalone language detection tool/chain for LangChain 😄 ### Twitter handle @deepsense_ai / @MaksOpp ### Tag maintainer @baskaryan @hwchase17 @hinthornw	12 months ago

maks-operlejn-ds	4cc4534d81	Data deanonymization (#10093 ) ### Description The feature for pseudonymizing data with ability to retrieve original text (deanonymization) has been implemented. In order to protect private data, such as when querying external APIs (OpenAI), it is worth pseudonymizing sensitive data to maintain full privacy. But then, after the model response, it would be good to have the data in the original form. I implemented the `PresidioReversibleAnonymizer`, which consists of two parts: 1. anonymization - it works the same way as `PresidioAnonymizer`, plus the object itself stores a mapping of made-up values to original ones, for example: ``` { "PERSON": { "<anonymized>": "<original>", "John Doe": "Slim Shady" }, "PHONE_NUMBER": { "111-111-1111": "555-555-5555" } ... } ``` 2. deanonymization - using the mapping described above, it matches fake data with original data and then substitutes it. Between anonymization and deanonymization user can perform different operations, for example, passing the output to LLM. ### Future works - instance anonymization - at this point, each occurrence of PII is treated as a separate entity and separately anonymized. Therefore, two occurrences of the name John Doe in the text will be changed to two different names. It is therefore worth introducing support for full instance detection, so that repeated occurrences are treated as a single object. - better matching and substitution of fake values for real ones - currently the strategy is based on matching full strings and then substituting them. Due to the indeterminism of language models, it may happen that the value in the answer is slightly changed (e.g. John Doe -> John or Main St, New York -> New York) and such a substitution is then no longer possible. Therefore, it is worth adjusting the matching for your needs. - Q&A with anonymization - when I'm done writing all the functionality, I thought it would be a cool resource in documentation to write a notebook about retrieval from documents using anonymization. An iterative process, adding new recognizers to fit the data, lessons learned and what to look out for ### Twitter handle @deepsense_ai / @MaksOpp --------- Co-authored-by: MaksOpp <maks.operlejn@gmail.com> Co-authored-by: Bagatur <baskaryan@gmail.com>	12 months ago
刘方瑞	890ed775a3	Resolve: VectorSearch enabled SQLChain? (#10177 ) Squashed from #7454 with updated features We have separated the `SQLDatabseChain` from `VectorSQLDatabseChain` and put everything into `experimental/`. Below is the original PR message from #7454. ------- We have been working on features to fill up the gap among SQL, vector search and LLM applications. Some inspiring works like self-query retrievers for VectorStores (for example [Weaviate](https://python.langchain.com/en/latest/modules/indexes/retrievers/examples/weaviate_self_query.html) and [others](https://python.langchain.com/en/latest/modules/indexes/retrievers/examples/self_query.html)) really turn those vector search databases into a powerful knowledge base! 🚀🚀 We are thinking if we can merge all in one, like SQL and vector search and LLMChains, making this SQL vector database memory as the only source of your data. Here are some benefits we can think of for now, maybe you have more 👀: With ALL data you have: since you store all your pasta in the database, you don't need to worry about the foreign keys or links between names from other data source. Flexible data structure: Even if you have changed your schema, for example added a table, the LLM will know how to JOIN those tables and use those as filters. SQL compatibility: We found that vector databases that supports SQL in the marketplace have similar interfaces, which means you can change your backend with no pain, just change the name of the distance function in your DB solution and you are ready to go! ### Issue resolved: - [Feature Proposal: VectorSearch enabled SQLChain?](https://github.com/hwchase17/langchain/issues/5122) ### Change made in this PR: - An improved schema handling that ignore `types.NullType` columns - A SQL output Parser interface in `SQLDatabaseChain` to enable Vector SQL capability and further more - A Retriever based on `SQLDatabaseChain` to retrieve data from the database for RetrievalQAChains and many others - Allow `SQLDatabaseChain` to retrieve data in python native format - Includes PR #6737 - Vector SQL Output Parser for `SQLDatabaseChain` and `SQLDatabaseChainRetriever` - Prompts that can implement text to VectorSQL - Corresponding unit-tests and notebook ### Twitter handle: - @MyScaleDB ### Tag Maintainer: Prompts / General: @hwchase17, @baskaryan DataLoaders / VectorStores / Retrievers: @rlancemartin, @eyurtsev ### Dependencies: No dependency added	12 months ago

ElReyZero	5dbae94e04	OpenAIEmbeddings: Add optional an optional parameter to skip empty embeddings (#10196 ) ## Description ### Issue This pull request addresses a lingering issue identified in PR #7070. In that previous pull request, an attempt was made to address the problem of empty embeddings when using the `OpenAIEmbeddings` class. While PR #7070 introduced a mechanism to retry requests for embeddings, it didn't fully resolve the issue as empty embeddings still occasionally persisted. ### Problem In certain specific use cases, empty embeddings can be encountered when requesting data from the OpenAI API. In some cases, these empty embeddings can be skipped or removed without affecting the functionality of the application. However, they might not always be resolved through retries, and their presence can adversely affect the functionality of applications relying on the `OpenAIEmbeddings` class. ### Solution To provide a more robust solution for handling empty embeddings, we propose the introduction of an optional parameter, `skip_empty`, in the `OpenAIEmbeddings` class. When set to `True`, this parameter will enable the behavior of automatically skipping empty embeddings, ensuring that problematic empty embeddings do not disrupt the processing flow. The developer will be able to optionally toggle this behavior if needed without disrupting the application flow. ## Changes Made - Added an optional parameter, `skip_empty`, to the `OpenAIEmbeddings` class. - When `skip_empty` is set to `True`, empty embeddings are automatically skipped without causing errors or disruptions. ### Example Usage ```python from openai.embeddings import OpenAIEmbeddings # Initialize the OpenAIEmbeddings class with skip_empty=True embeddings = OpenAIEmbeddings(api_key="your_api_key", skip_empty=True) # Request embeddings, empty embeddings are automatically skipped. docs is a variable containing the already splitted text. results = embeddings.embed_documents(docs) # Process results without interruption from empty embeddings ```	12 months ago

Dependencies: the `pyproject.toml` and `poetry.lock` have the newest version of cassIO (the very same as in the Cassandra vector store metadata PR, submitted as #9280). If I may suggest, this issue and #9280 might be reviewed together (as they bring the same poetry changes along), so I'm tagging @baskaryan who already helped out a little with poetry-related conflicts there. (Thank you!) I'd be happy to add a short notebook if this is deemed necessary (but it seems to me that, contrary e.g. to vector stores, caches are not covered in specific notebooks).

Viktor Zhemchuzhnikov	507e46844e	Extend SQLChatMessageHistory (#9849 ) ### Description There is a really nice class for saving chat messages into a database - SQLChatMessageHistory. It leverages SqlAlchemy to be compatible with any supported database (in contrast with PostgresChatMessageHistory, which is basically the same but is limited to Postgres). However, the class is not really customizable in terms of what you can store. I can imagine a lot of use cases, when one will need to save a message date, along with some additional metadata. To solve this, I propose to extract the converting logic from BaseMessage to SQLAlchemy model (and vice versa) into a separate class - message converter. So instead of rewriting the whole SQLChatMessageHistory class, a user will only need to write a custom model and a simple mapping class, and pass its instance as a parameter. I also noticed that there is no documentation on this class, so I added that too, with an example of custom message converter. ### Issue N/A ### Dependencies N/A ### Tag maintainer Not yet ### Twitter handle N/A	12 months ago

Davide Menini	b8baead70c	fix (Html2TextTransformer): allow configuration of html2text (#9914 ) Hi, this PR enables configuring the html2text package, instead of being bound to use the hardcoded values. While simply passing `ignore_links` and `ignore_images` to the `transform_documents` method was possible, I preferred passing them to the `__init__` method for 2 reasons: 1. It is more efficient in case of subsequent calls to `transform_documents`. 2. It allows to move the "complexity" to the instantiation, keeping the actual execution simple and general enough. IMO the transformers should all follow this pattern, allowing something like this: ```python # Instantiate transformers transformers = [ TransformerA(foo='bar'), TransformerB(bar='foo'), # others ] # During execution, call them sequentially documents = ... for tr in transformers: documents = tr.transform_documents(documents) ``` Thanks for the reviews! --------- Co-authored-by: taamedag <Davide.Menini@swisscom.com>	12 months ago

Blake (Yung Cher Ho)	f4bed8a04c	Takeoff baseurl support (#10091 ) ## Description This PR introduces a minor change to the TitanTakeoff integration. Instead of specifying a port on localhost, this PR will allow users to specify a baseURL instead. This will allow users to use the integration if they have TitanTakeoff deployed externally (not on localhost). This removes the hardcoded reference to localhost "http://localhost:{port}". ### Info about Titan Takeoff Titan Takeoff is an inference server created by [TitanML](https://www.titanml.co/) that allows you to deploy large language models locally on your hardware in a single command. Most generative model architectures are included, such as Falcon, Llama 2, GPT2, T5 and many more. Read more about Titan Takeoff here: - [Blog](https://medium.com/@TitanML/introducing-titan-takeoff-6c30e55a8e1e) - [Docs](https://docs.titanml.co/docs/titan-takeoff/getting-started) ### Dependencies No new dependencies are introduced. However, users will need to install the titan-iris package in their local environment and start the Titan Takeoff inferencing server in order to use the Titan Takeoff integration. Thanks for your help and please let me know if you have any questions. cc: @hwchase17 @baskaryan --------- Co-authored-by: Harrison Chase <hw.chase.17@gmail.com>	12 months ago
Eddie Cohen	565c021730	Add ne comparator (#10006 ) Description: Adds the not comparator and operator to pinecone, chroma and deeplake. Issue: Not a registered issue but when using a selfqueryretriever with pinecone I got this error + stacktrace when I entered a query that asked to not include specific data: > raised following `error:` > Received unrecognized function ne. Valid functions are [<Operator.AND: 'and'>, <Operator.OR: 'or'>, <Operator.NOT: 'not'>, <Comparator.EQ: 'eq'>, <Comparator.GT: 'gt'>, <Comparator.GTE: 'gte'>, <Comparator.LT: 'lt'>, <Comparator.LTE: 'lte'>] I noticed that chroma and deeplake also support not equals/not filtering so I added it there as well [pinecone](https://docs.pinecone.io/docs/metadata-filtering#metadata-query-language) [chroma](https://docs.trychroma.com/usage-guide#filtering-by-metadata) [deeplake](https://docs.activeloop.ai/enterprise-features/compute-engine/querying-datasets/query-syntax#and-or-not)	12 months ago
