Zander Chase	9b9b231e10	Update some Tools Docs (#3913 ) Haven't gotten to all of them, but this: - Updates some of the tools notebooks to actually instantiate a tool (many just show a 'utility' rather than a tool. More changes to come in separate PR) - Move the `Tool` and decorator definitions to `langchain/tools/base.py` (but still export from `langchain.agents`) - Add scene explain to the load_tools() function - Add unit tests for public apis for the langchain.tools and langchain.agents modules	1 year ago
Zander Chase	84ea17b786	Move Tool Validation (#3923 ) Move tool validation to each implementation of the Agent. Another alternative would be to adjust the `_validate_tools()` signature to accept the output parser (and format instructions) and add logic there. Something like `parser.outputs_structured_actions(format_instructions)` But don't think that's needed right now.	1 year ago
Eugene Yurtsev	7cce68a051	Add minimal file system blob loader (#3669 ) This adds a minimal file system blob loader. If looks good, this PR will be merged and a few additional enhancements will be made.	1 year ago
Zura Isakadze	647bbf61c1	Add SQLiteChatMessageHistory (#3534 ) It's based on already existing `PostgresChatMessageHistory` Use case somewhere in between multiple files and Postgres storage.	1 year ago
James Brotchie	921894960b	Add ChatModel, LLM, and Embeddings for Google's PaLM APIs (#3575 ) - Add langchain.llms.GooglePalm for text completion, - Add langchain.chat_models.ChatGooglePalm for chat completion, - Add langchain.embeddings.GooglePalmEmbeddings for sentence embeddings, - Add example field to HumanMessage and AIMessage so that users can feed in examples into the PaLM Chat API, - Add system and unit tests. Note async completion for the Text API is not yet supported and will be included in a future PR. Happy for feedback on any aspect of this PR, especially our choice of adding an example field to Human and AI Message objects to enable passing example messages to the API.	1 year ago
Roma	d15f481352	Add unit test to output parsers (#3911 ) This pull request adds unit tests for various output parsers (BooleanOutputParser, CommaSeparatedListOutputParser, and StructuredOutputParser) to ensure their correct functionality and to increase code reliability and maintainability. The tests cover both valid and invalid input cases. Changes: Added unit tests for BooleanOutputParser. Added unit tests for CommaSeparatedListOutputParser. Added unit tests for StructuredOutputParser. Testing: All new unit tests have been executed, and they pass successfully. The overall test suite has been run, and all tests pass. Notes: These tests cover both successful parsing scenarios and error handling for invalid inputs. If any new output parsers are added in the future, corresponding unit tests should also be created to maintain coverage.	1 year ago

Mike Wang	512c24fc9c	[annotation improvement] Make AgentType->Class Conversion More Scalable (#3749 ) In the current solution, AgentType and AGENT_TO_CLASS are placed in two separate files and both manually maintained. This might cause inconsistency when we update either of them. — latest — based on the discussion with hwchase17, we don’t know how to further use the newly introduced AgentTypeConfig type, so it doesn’t make sense yet to add it. Instead, it’s better to move the dictionary to another file to keep the loading.py file clear. The consistency is a good point. Instead of asserting the consistency during linting, we added a unittest for consistency check. I think it works as auto unittest is triggered every time with clear failure notice. (well, force push is possible, but we all know what we are doing, so let’s show trust. :>) ~~This PR includes~~ - ~~Introduced AgentTypeConfig as the source of truth of all AgentType related meta data.~~ - ~~Each AgentTypeConfig is a annotated class type which can be used for annotation in other places.~~ - ~~Each AgentTypeConfig can be easily extended when we have more meta data needs.~~ - ~~Strong assertion to ensure AgentType and AGENT_TO_CLASS are always consistent.~~ - ~~Made AGENT_TO_CLASS automatically generated.~~ ~~Test Plan:~~ - ~~since this change is focusing on annotation, lint is the major test focus.~~ - ~~lint, format and test passed on local.~~	1 year ago

Jon Saginaw	f8d69e4e52	Enhancement: Blockchain Document Loader with better Metadata support (#3710 ) This PR includes some minor alignment updates, including: - metadata object extended to support contractAddress, blockchainType, and tokenId - notebook doc better aligned to standard langchain format - startToken changed from int to str to support multiple hex value types on the Alchemy API The updated metadata will look like the below. It's possible for a single contractAddress to exist across multiple blockchains (e.g. Ethereum, Polygon, etc.) so it's important to include the blockchainType. ``` metadata = {"source": self.contract_address, "blockchain": self.blockchainType, "tokenId": tokenId} ```	1 year ago

Rafal Wojdyla	160bfae93f	Add `DocstoreFn` - lookup doc via arbitrary function (#3760 ) This partially addresses https://github.com/hwchase17/langchain/issues/1524, but it's also useful for some of our use cases. This `DocstoreFn` allows to lookup a document given a function that accepts the `search` string without the need to implement a custom `Docstore`. This could be useful when: * you don't want to implement a `Docstore` just to provide a custom `search` * it's expensive to construct an `InMemoryDocstore`/dict * you retrieve documents from remote sources * you just want to reuse existing objects	1 year ago

Zander Chase	da7b51455c	Dynamic tool -> single purpose (#3697 ) I think the logic of https://github.com/hwchase17/langchain/pull/3684#pullrequestreview-1405358565 is too confusing. I prefer this alternative because: - All `Tool()` implementations by default will be treated the same as before. No breaking changes. - Less reliance on pydantic magic - The decorator (which only is typed as returning a callable) can infer schema and generate a structured tool - Either way, the recommended way to create a custom tool is through inheriting from the base tool	1 year ago
Zander Chase	4654c58f72	Add validation on agent instantiation for multi-input tools (#3681 ) Tradeoffs here: - No lint-time checking for compatibility - Differs from JS package - The signature inference, etc. in the base tool isn't simple - The `args_schema` is optional Pros: - Forwards compatibility retained - Doesn't break backwards compatibility - User doesn't have to think about which class to subclass (single base tool or dynamic `Tool` interface regardless of input) - No need to change the load_tools, etc. interfaces Co-authored-by: Hasan Patel <mangafield@gmail.com>	1 year ago

Eugene Yurtsev	5d02010763	Introduce Blob and Blob Loader interface (#3603 ) This PR introduces a Blob data type and a Blob loader interface. This is the first of a sequence of PRs that follows this proposal: https://github.com/hwchase17/langchain/pull/2833 The primary goals of these abstraction are: * Decouple content loading from content parsing code. * Help duplicated content loading code from document loaders. * Make lazy loading a default for langchain.	1 year ago

Kermani	4a246e2fd6	Allow clearing cache and fix gptcache (#3493 ) This PR * Adds `clear` method for `BaseCache` and implements it for various caches * Adds the default `init_func=None` and fixes gptcache integtest * Since right now integtest is not running in CI, I've verified the changes by running `docs/modules/models/llms/examples/llm_caching.ipynb` (until proper e2e integtest is done in CI)	1 year ago
cs0lar	440c98e24b	Fix/issue 2695 (#3608 ) ## Background fixes #2695 ## Changes The `add_text` method uses the internal embedding function if one was passes to the `Weaviate` constructor. NOTE: the latest merge on the `Weaviate` class made the specification of a `weaviate_api_key` mandatory which might not be desirable for all users and connection methods (for example weaviate also support Embedded Weaviate which I am happy to add support to here if people think it's desirable). I wrapped the fetching of the api key into a try catch in order to allow the `weaviate_api_key` to be unspecified. Do let me know if this is unsatisfactory. ## Test Plan added test for `add_texts` method.	1 year ago
leo-gan	36c59e0c25	`Arxiv` document loader (#3627 ) It makes sense to use `arxiv` as another source of the documents for downloading. - Added the `arxiv` document_loader, based on the `utilities/arxiv.py:ArxivAPIWrapper` - added tests - added an example notebook - sorted `__all__` in `__init__.py` (otherwise it is hard to find a class in the very long list)	1 year ago
