Mike Wang	ce4fea983b	[simple] added test case and improve self class return type annotation (#3773 ) a simple follow up of https://github.com/hwchase17/langchain/pull/3748 - added test case - improve annotation when function return type is class itself.	1 year ago

Aurélien SCHILTZ	502ba6a0be	Fix type annotation for SQLDatabaseToolkit.llm (#3581 ) Currently `langchain.agents.agent_toolkits.SQLDatabaseToolkit` has a field `llm` with type `BaseLLM`. This breaks initialization for some LLMs. For example, trying to use it with GPT4: ``` from langchain.sql_database import SQLDatabase from langchain.chat_models import ChatOpenAI from langchain.agents.agent_toolkits import SQLDatabaseToolkit db = SQLDatabase.from_uri("some_db_uri") llm = ChatOpenAI(model_name="gpt-4") toolkit = SQLDatabaseToolkit(db=db, llm=llm) # pydantic.error_wrappers.ValidationError: 1 validation error for SQLDatabaseToolkit # llm # Can't instantiate abstract class BaseLLM with abstract methods _agenerate, _generate, _llm_type (type=type_error) ``` Seems like much of the rest of the codebase has switched from BaseLLM to BaseLanguageModel. This PR makes the change for SQLDatabaseToolkit as well	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
Harrison Chase	b7ae9f715d	Langchain with reddit (#3661 ) (#3768 ) I have added a reddit document loader which fetches the text from the Posts of Subreddits or Reddit users, using the `praw` Python package. I have also added an example notebook reddit.ipynb in order to guide users to use this dataloader. This code was made in format similar to twiiter document loader. I have run code formating, linting and also checked the code myself for different scenarios. This is my first contribution to an open source project and I am really excited about this. If you want to suggest some improvements in my code, I will be happy to do it. :) Co-authored-by: Taaha Bajwa <taaha.s.bajwa@gmail.com>	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	37ed6f2177	Handle length safe embedding only if needed (#3723 ) Re: https://github.com/hwchase17/langchain/issues/3722 Copy pasting context from the issue: `1bf1c37c0c/langchain/embeddings/openai.py (L210-L211)` Means that the length safe embedding method is "always" used, initial implementation https://github.com/hwchase17/langchain/pull/991 has the `embedding_ctx_length` set to -1 (meaning you had to opt-in for the length safe method), https://github.com/hwchase17/langchain/pull/2330 changed that to max length of OpenAI embeddings v2, meaning the length safe method is used at all times. How about changing that if branch to use length safe method only when needed, meaning when the text is longer than the max context length?	1 year ago

mbchang	4eefea0fe8	new example: single agent, simulated environment (openai gym) (#3758 ) For many applications of LLM agents, the environment is real (internet, database, REPL, etc). However, we can also define agents to interact in simulated environments like text-based games. This is an example of how to create a simple agent-environment interaction loop with [Gymnasium](https://github.com/Farama-Foundation/Gymnasium) (formerly [OpenAI Gym](https://github.com/openai/gym)).	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

The file combine_docs.md doesn't exist anymore and thus provide 404 - Page not found.

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

mbchang	1da3ee1386	Multiagent authoritarian (#3686 ) This notebook showcases how to implement a multi-agent simulation where a privileged agent decides who to speak. This follows the polar opposite selection scheme as [multi-agent decentralized speaker selection](https://python.langchain.com/en/latest/use_cases/agent_simulations/multiagent_bidding.html). We show an example of this approach in the context of a fictitious simulation of a news network. This example will showcase how we can implement agents that - think before speaking - terminate the conversation	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
