Piyush Jain	94cf71ecfa	Updated Neptune graph to use boto (#10121 ) ## Description This PR updates the `NeptuneGraph` class to start using the boto API for connecting to the Neptune service. With boto integration, the graph class now supports authenticating requests using Sigv4; this is encapsulated with the boto API, and users only have to ensure they have the correct AWS credentials setup in their workspace to work with the graph class. This PR also introduces a conditional prompt that uses a simpler prompt when using the `Anthropic` model provider. 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.	12 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. Additional Documentation: For a more comprehensive understanding and to explore a myriad of useful options that are now accessible, please refer to the Weaviate documentation: - [Fusion Ranking Method](https://weaviate.io/developers/weaviate/search/hybrid#fusion-ranking-method) - [Selected Properties Only](https://weaviate.io/developers/weaviate/search/hybrid#selected-properties-only) - [Weight Boost Searched Properties](https://weaviate.io/developers/weaviate/search/hybrid#weight-boost-searched-properties) - [With a Custom Vector](https://weaviate.io/developers/weaviate/search/hybrid#with-a-custom-vector) Tag Maintainer:** @hwchase17 - I have tagged you based on your frequent contributions to the pertinent file, `/retrievers/weaviate_hybrid_search.py`.

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. (mypy gives unrelated errors in other modules, which clearly don't depend on the content of this PR). Thank you! Stefano --------- Co-authored-by: Bagatur <baskaryan@gmail.com>	1 year ago

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)	1 year ago

Taqi Jaffri	21fbbe83a7	Fix fine-tuned replicate models with faster cold boot (#10512 ) With the latest support for faster cold boot in replicate https://replicate.com/blog/fine-tune-cold-boots it looks like the replicate LLM support in langchain is broken since some internal replicate inputs are being returned. 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>	1 year 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]) ```	1 year 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	1 year 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>	1 year 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	1 year 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 ```	1 year ago

Integration tests are included. Moreover, linting and type checks are all passing on my machine. 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	1 year ago

Lorenzo	00a7c31ffd	Fix: Nested Dicts Handling of Document Metadata (#9880 ) ## Description When the `MultiQueryRetriever` is used to get the list of documents relevant according to a query, inside a vector store, and at least one of these contain metadata with nested dictionaries, a `TypeError: unhashable type: 'dict'` exception is thrown. This is caused by the `unique_union` function which, to guarantee the uniqueness of the returned documents, tries, unsuccessfully, to hash the nested dictionaries and use them as a part of key. ```python unique_documents_dict = { (doc.page_content, tuple(sorted(doc.metadata.items()))): doc for doc in documents } ``` ## Issue #9872 (MultiQueryRetriever (get_relevant_documents) raises TypeError: unhashable type: 'dict' with dic metadata) ## Solution A possible solution is to dump the metadata dict to a string and use it as a part of hashed key. ```python unique_documents_dict = { (doc.page_content, json.dumps(doc.metadata, sort_keys=True)): doc for doc in documents } ``` --------- Co-authored-by: Bagatur <baskaryan@gmail.com>	1 year 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>	1 year 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.

Davide Menini	3f8f3de28e	fix (parsers/json): do not escape double quotes if already escaped (#9916 ) This PR fixes an issues I found when upgrading to a more recent version of Langchain. I was using 0.0.142 before, and this issue popped up already when the `_custom_parser` was added to `output_parsers/json`. Anyway, the issue is that the parser tries to escape quotes when they are double-escaped (e.g. `\\"`), leading to OutputParserException. This is particularly undesired in my app, because I have an Agent that uses a single input Tool, which expects as input a JSON string with the structure: ```python { "foo": string, "bar": string } ``` The LLM (GPT3.5) response is (almost) always something like `"action_input": "{\\"foo\\": \\"bar\\", \\"bar\\": \\"foo\\"}"` and since the upgrade this is not correctly parsed. --------- Co-authored-by: taamedag <Davide.Menini@swisscom.com>	1 year ago

Jiří Moravčík	86646ec555	feat: Add `ApifyWrapper` class (#10067 ) If you look at documentation https://python.langchain.com/docs/integrations/tools/apify (or the actual file https://github.com/langchain-ai/langchain/blob/master/docs/extras/integrations/tools/apify.ipynb ), there's a class `ApifyWrapper` mentioned. It seems it got lost in some refactoring, i.e. it does not exist in the codebase ATM. I just propose to add it back. It would fix issues e.g. https://github.com/langchain-ai/langchain/issues/8307 or https://github.com/langchain-ai/langchain/issues/8201 To add, Apify is a wanted integration, e.g. see https://twitter.com/hwchase17/status/1695490295914545626 or https://twitter.com/hwchase17/status/1695470765343461756 Lastly, I offer taking ownership of the Apify-related parts of the codebase, so you can tag me if anything is needed.	1 year ago
Robert Perrotta	02e51f4217	update_forward_refs for Run (#9969 ) Adds a call to Pydantic's `update_forward_refs` for the `Run` class (in addition to the `ChainRun` and `ToolRun` classes, for which that method is already called). Without it, the self-reference of child classes (type `List[Run]`) is problematic. For example: ```python from langchain.callbacks import StdOutCallbackHandler from langchain.chains import LLMChain from langchain.llms import OpenAI from langchain.prompts import PromptTemplate from wandb.integration.langchain import WandbTracer llm = OpenAI() prompt = PromptTemplate.from_template("1 + {number} = ") chain = LLMChain(llm=llm, prompt=prompt, callbacks=[StdOutCallbackHandler(), WandbTracer()]) print(chain.run(number=2)) ``` results in the following output before the change ``` WARNING:root:Error in on_chain_start callback: field "child_runs" not yet prepared so type is still a ForwardRef, you might need to call Run.update_forward_refs(). > Entering new LLMChain chain... Prompt after formatting: 1 + 2 = WARNING:root:Error in on_chain_end callback: No chain Run found to be traced > Finished chain. 3 ``` but afterwards the callback error messages are gone.	1 year ago

The database supports multiple index types and similarity calculation methods, with a single index supporting vector scales up to 1 billion and capable of handling millions of QPS with millisecond-level query latency. Tencent Cloud VectorDB not only provides external knowledge bases for large models to improve their accuracy, but also has wide applications in AI fields such as recommendation systems, NLP services, computer vision, and intelligent customer service.

Bagatur	6b5a970949	refactor(document_loaders): abstract page evaluation logic in PlaywrightURLLoader (#9995 ) This PR brings structural updates to `PlaywrightURLLoader`, aiming at making the code more readable and extensible through the abstraction of page evaluation logic. These changes also align this implementation with a similar structure used in LangChain.js. The key enhancements include: 1. Introduction of 'PlaywrightEvaluator', an abstract base class for all evaluators. 2. Creation of 'UnstructuredHtmlEvaluator', a concrete class implementing 'PlaywrightEvaluator', which uses `unstructured` library for processing page's HTML content. 3. Extension of 'PlaywrightURLLoader' constructor to optionally accept an evaluator of the type 'PlaywrightEvaluator'. It defaults to 'UnstructuredHtmlEvaluator' if no evaluator is provided. 4. Refactoring of 'load' and 'aload' methods to use the 'evaluate' and 'evaluate_async' methods of the provided 'PageEvaluator' for page content handling. This update brings flexibility to 'PlaywrightURLLoader' as it can now utilize different evaluators for page processing depending on the requirement. The abstraction also improves code maintainability and readability. Twitter: @ywkim	1 year ago

maks-operlejn-ds	a8f804a618	Add data anonymizer (#9863 ) ### Description The feature for anonymizing data 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. Anonynization consists of two steps: 1. Identification: Identify all data fields that contain personally identifiable information (PII). 2. Replacement: Replace all PIIs with pseudo values or codes that do not reveal any personal information about the individual but can be used for reference. We're not using regular encryption, because the language model won't be able to understand the meaning or context of the encrypted data. We use Microsoft Presidio together with Faker framework for anonymization purposes because of the wide range of functionalities they provide. The full implementation is available in `PresidioAnonymizer`. ### Future works - deanonymization - add the ability to reverse anonymization. For example, the workflow could look like this: `anonymize -> LLMChain -> deanonymize`. By doing this, we will retain anonymity in requests to, for example, OpenAI, and then be able restore the original data. - 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. ### Twitter handle @deepsense_ai / @MaksOpp --------- Co-authored-by: MaksOpp <maks.operlejn@gmail.com> Co-authored-by: Bagatur <baskaryan@gmail.com>	1 year ago

One can see this by adding a line like `reveal_type(type_to_loader_dict)` and running mypy, which will get mypy to show what type it has inferred for that value. Adding an explicit type hint to help out mypy avoids the need for a mypy suppression and allows the code to type-check cleanly.	1 year ago

Sam Partee	a28eea5767	Redis metadata filtering and specification, index customization (#8612 ) ### Description The previous Redis implementation did not allow for the user to specify the index configuration (i.e. changing the underlying algorithm) or add additional metadata to use for querying (i.e. hybrid or "filtered" search). This PR introduces the ability to specify custom index attributes and metadata attributes as well as use that metadata in filtered queries. Overall, more structure was introduced to the Redis implementation that should allow for easier maintainability moving forward. # New Features The following features are now available with the Redis integration into Langchain ## Index schema generation The schema for the index will now be automatically generated if not specified by the user. For example, the data above has the multiple metadata categories. The the following example ```python from langchain.embeddings import OpenAIEmbeddings from langchain.vectorstores.redis import Redis embeddings = OpenAIEmbeddings() rds, keys = Redis.from_texts_return_keys( texts, embeddings, metadatas=metadata, redis_url="redis://localhost:6379", index_name="users" ) ``` Loading the data in through this and the other ``from_documents`` and ``from_texts`` methods will now generate index schema in Redis like the following. view index schema with the ``redisvl`` tool. [link](redisvl.com) ```bash $ rvl index info -i users ``` Index Information: \| Index Name \| Storage Type \| Prefixes \| Index Options \| Indexing \| \|--------------\|----------------\|---------------\|-----------------\|------------\| \| users \| HASH \| ['doc:users'] \| [] \| 0 \| Index Fields: \| Name \| Attribute \| Type \| Field Option \| Option Value \| \|----------------\|----------------\|---------\|----------------\|----------------\| \| user \| user \| TEXT \| WEIGHT \| 1 \| \| job \| job \| TEXT \| WEIGHT \| 1 \| \| credit_score \| credit_score \| TEXT \| WEIGHT \| 1 \| \| content \| content \| TEXT \| WEIGHT \| 1 \| \| age \| age \| NUMERIC \| \| \| \| content_vector \| content_vector \| VECTOR \| \| \| ### Custom Metadata specification The metadata schema generation has the following rules 1. All text fields are indexed as text fields. 2. All numeric fields are index as numeric fields. If you would like to have a text field as a tag field, users can specify overrides like the following for the example data ```python # this can also be a path to a yaml file index_schema = { "text": [{"name": "user"}, {"name": "job"}], "tag": [{"name": "credit_score"}], "numeric": [{"name": "age"}], } rds, keys = Redis.from_texts_return_keys( texts, embeddings, metadatas=metadata, redis_url="redis://localhost:6379", index_name="users" ) ``` This will change the index specification to Index Information: \| Index Name \| Storage Type \| Prefixes \| Index Options \| Indexing \| \|--------------\|----------------\|----------------\|-----------------\|------------\| \| users2 \| HASH \| ['doc:users2'] \| [] \| 0 \| Index Fields: \| Name \| Attribute \| Type \| Field Option \| Option Value \| \|----------------\|----------------\|---------\|----------------\|----------------\| \| user \| user \| TEXT \| WEIGHT \| 1 \| \| job \| job \| TEXT \| WEIGHT \| 1 \| \| content \| content \| TEXT \| WEIGHT \| 1 \| \| credit_score \| credit_score \| TAG \| SEPARATOR \| , \| \| age \| age \| NUMERIC \| \| \| \| content_vector \| content_vector \| VECTOR \| \| \| and throw a warning to the user (log output) that the generated schema does not match the specified schema. ```text index_schema does not match generated schema from metadata. index_schema: {'text': [{'name': 'user'}, {'name': 'job'}], 'tag': [{'name': 'credit_score'}], 'numeric': [{'name': 'age'}]} generated_schema: {'text': [{'name': 'user'}, {'name': 'job'}, {'name': 'credit_score'}], 'numeric': [{'name': 'age'}]} ``` As long as this is on purpose, this is fine. The schema can be defined as a yaml file or a dictionary ```yaml text: - name: user - name: job tag: - name: credit_score numeric: - name: age ``` and you pass in a path like ```python rds, keys = Redis.from_texts_return_keys( texts, embeddings, metadatas=metadata, redis_url="redis://localhost:6379", index_name="users3", index_schema=Path("sample1.yml").resolve() ) ``` Which will create the same schema as defined in the dictionary example Index Information: \| Index Name \| Storage Type \| Prefixes \| Index Options \| Indexing \| \|--------------\|----------------\|----------------\|-----------------\|------------\| \| users3 \| HASH \| ['doc:users3'] \| [] \| 0 \| Index Fields: \| Name \| Attribute \| Type \| Field Option \| Option Value \| \|----------------\|----------------\|---------\|----------------\|----------------\| \| user \| user \| TEXT \| WEIGHT \| 1 \| \| job \| job \| TEXT \| WEIGHT \| 1 \| \| content \| content \| TEXT \| WEIGHT \| 1 \| \| credit_score \| credit_score \| TAG \| SEPARATOR \| , \| \| age \| age \| NUMERIC \| \| \| \| content_vector \| content_vector \| VECTOR \| \| \| ### Custom Vector Indexing Schema Users with large use cases may want to change how they formulate the vector index created by Langchain To utilize all the features of Redis for vector database use cases like this, you can now do the following to pass in index attribute modifiers like changing the indexing algorithm to HNSW. ```python vector_schema = { "algorithm": "HNSW" } rds, keys = Redis.from_texts_return_keys( texts, embeddings, metadatas=metadata, redis_url="redis://localhost:6379", index_name="users3", vector_schema=vector_schema ) ``` A more complex example may look like ```python vector_schema = { "algorithm": "HNSW", "ef_construction": 200, "ef_runtime": 20 } rds, keys = Redis.from_texts_return_keys( texts, embeddings, metadatas=metadata, redis_url="redis://localhost:6379", index_name="users3", vector_schema=vector_schema ) ``` All names correspond to the arguments you would set if using Redis-py or RedisVL. (put in doc link later) ### Better Querying Both vector queries and Range (limit) queries are now available and metadata is returned by default. The outputs are shown. ```python >>> query = "foo" >>> results = rds.similarity_search(query, k=1) >>> print(results) [Document(page_content='foo', metadata={'user': 'derrick', 'job': 'doctor', 'credit_score': 'low', 'age': '14', 'id': 'doc:users:657a47d7db8b447e88598b83da879b9d', 'score': '7.15255737305e-07'})] >>> results = rds.similarity_search_with_score(query, k=1, return_metadata=False) >>> print(results) # no metadata, but with scores [(Document(page_content='foo', metadata={}), 7.15255737305e-07)] >>> results = rds.similarity_search_limit_score(query, k=6, score_threshold=0.0001) >>> print(len(results)) # range query (only above threshold even if k is higher) 4 ``` ### Custom metadata filtering A big advantage of Redis in this space is being able to do filtering on data stored alongside the vector itself. With the example above, the following is now possible in langchain. The equivalence operators are overridden to describe a new expression language that mimic that of [redisvl](redisvl.com). This allows for arbitrarily long sequences of filters that resemble SQL commands that can be used directly with vector queries and range queries. There are two interfaces by which to do so and both are shown. ```python >>> from langchain.vectorstores.redis import RedisFilter, RedisNum, RedisText >>> age_filter = RedisFilter.num("age") > 18 >>> age_filter = RedisNum("age") > 18 # equivalent >>> results = rds.similarity_search(query, filter=age_filter) >>> print(len(results)) 3 >>> job_filter = RedisFilter.text("job") == "engineer" >>> job_filter = RedisText("job") == "engineer" # equivalent >>> results = rds.similarity_search(query, filter=job_filter) >>> print(len(results)) 2 # fuzzy match text search >>> job_filter = RedisFilter.text("job") % "eng*" >>> results = rds.similarity_search(query, filter=job_filter) >>> print(len(results)) 2 # combined filters (AND) >>> combined = age_filter & job_filter >>> results = rds.similarity_search(query, filter=combined) >>> print(len(results)) 1 # combined filters (OR) >>> combined = age_filter \| job_filter >>> results = rds.similarity_search(query, filter=combined) >>> print(len(results)) 4 ``` All the above filter results can be checked against the data above. ### Other - Issue: #3967 - Dependencies: No added dependencies - Tag maintainer: @hwchase17 @baskaryan @rlancemartin - Twitter handle: @sampartee --------- Co-authored-by: Naresh Rangan <naresh.rangan0@walmart.com> Co-authored-by: Bagatur <baskaryan@gmail.com>	1 year ago
nikhilkjha	d57d08fd01	Initial commit for comprehend moderator (#9665 ) This PR implements a custom chain that wraps Amazon Comprehend API calls. The custom chain is aimed to be used with LLM chains to provide moderation capability that let’s you detect and redact PII, Toxic and Intent content in the LLM prompt, or the LLM response. The implementation accepts a configuration object to control what checks will be performed on a LLM prompt and can be used in a variety of setups using the LangChain expression language to not only detect the configured info in chains, but also other constructs such as a retriever. The included sample notebook goes over the different configuration options and how to use it with other chains. ### Usage sample ```python from langchain_experimental.comprehend_moderation import BaseModerationActions, BaseModerationFilters moderation_config = { "filters":[ BaseModerationFilters.PII, BaseModerationFilters.TOXICITY, BaseModerationFilters.INTENT ], "pii":{ "action": BaseModerationActions.ALLOW, "threshold":0.5, "labels":["SSN"], "mask_character": "X" }, "toxicity":{ "action": BaseModerationActions.STOP, "threshold":0.5 }, "intent":{ "action": BaseModerationActions.STOP, "threshold":0.5 } } comp_moderation_with_config = AmazonComprehendModerationChain( moderation_config=moderation_config, #specify the configuration client=comprehend_client, #optionally pass the Boto3 Client verbose=True ) template = """Question: {question} Answer:""" prompt = PromptTemplate(template=template, input_variables=["question"]) responses = [ "Final Answer: A credit card number looks like 1289-2321-1123-2387. A fake SSN number looks like 323-22-9980. John Doe's phone number is (999)253-9876.", "Final Answer: This is a really shitty way of constructing a birdhouse. This is fucking insane to think that any birds would actually create their motherfucking nests here." ] llm = FakeListLLM(responses=responses) llm_chain = LLMChain(prompt=prompt, llm=llm) chain = ( prompt \| comp_moderation_with_config \| {llm_chain.input_keys[0]: lambda x: x['output'] } \| llm_chain \| { "input": lambda x: x['text'] } \| comp_moderation_with_config ) response = chain.invoke({"question": "A sample SSN number looks like this 123-456-7890. Can you give me some more samples?"}) print(response['output']) ``` ### Output ``` > Entering new AmazonComprehendModerationChain chain... Running AmazonComprehendModerationChain...

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.

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
