Ankush Gola	b82cbd1be0	Use `run` and `arun` in place of `combine_docs` and `acombine_docs` (#2635 ) `combine_docs` does not go through the standard chain call path which means that chain callbacks won't be triggered, meaning QA chains won't be traced properly, this fixes that. Also fix several errors in the chat_vector_db notebook	1 year ago
Vashisht Madhavan	aa439ac2ff	Adding an in-context QA evaluation chain + chain of thought reasoning chain for improved accuracy (#2444 ) Right now, eval chains require an answer for every question. It's cumbersome to collect this ground truth so getting around this issue with 2 things: * Adding a context param in `ContextQAEvalChain` and simply evaluating if the question is answered accurately from context * Adding chain of though explanation prompting to improve the accuracy of this w/o GT. This also gets to feature parity with openai/evals which has the same contextual eval w/o GT. TODO in follow-up: * Better prompt inheritance. No need for seperate prompt for CoT reasoning. How can we merge them together --------- Co-authored-by: Vashisht Madhavan <vashishtmadhavan@Vashs-MacBook-Pro.local>	1 year ago
William FH	f240651bd8	Add Request body (#2507 ) This still doesn't handle the following - non-JSON media types - anyOf, allOf, oneOf's And doesn't emit the typescript definitions for referred types yet, but that can be saved for a separate PR. Also, we could have better support for Swagger 2.0 specs and OpenAPI 3.0.3 (can use the same lib for the latter) recommend offline conversion for now.	1 year ago
Zach Jones	13d1df2140	Feature: AgentExecutor execution time limit (#2399 ) `AgentExecutor` already has support for limiting the number of iterations. But the amount of time taken for each iteration can vary quite a bit, so it is difficult to place limits on the execution time. This PR adds a new field `max_execution_time` to the `AgentExecutor` model. When called asynchronously, the agent loop is wrapped in an `asyncio.timeout()` context which triggers the early stopping response if the time limit is reached. When called synchronously, the agent loop checks for both the max_iteration limit and the time limit after each iteration. When used asynchronously `max_execution_time` gives really tight control over the max time for an execution chain. When used synchronously, the chain can unfortunately exceed max_execution_time, but it still gives more control than trying to estimate the number of max_iterations needed to cap the execution time. --------- Co-authored-by: Zachary Jones <zjones@zetaglobal.com>	1 year ago

Shrined	10dab053b4	Add Enum for agent types (#2321 ) This pull request adds an enum class for the various types of agents used in the project, located in the `agent_types.py` file. Currently, the project is using hardcoded strings for the initialization of these agents, which can lead to errors and make the code harder to maintain. With the introduction of the new enums, the code will be more readable and less error-prone. The new enum members include: - ZERO_SHOT_REACT_DESCRIPTION - REACT_DOCSTORE - SELF_ASK_WITH_SEARCH - CONVERSATIONAL_REACT_DESCRIPTION - CHAT_ZERO_SHOT_REACT_DESCRIPTION - CHAT_CONVERSATIONAL_REACT_DESCRIPTION In this PR, I have also replaced the hardcoded strings with the appropriate enum members throughout the codebase, ensuring a smooth transition to the new approach.	1 year ago

Jon Luo	0a1b1806e9	sql: do not hard code the LIMIT clause in the table_info section (#1563 ) Seeing a lot of issues in Discord in which the LLM is not using the correct LIMIT clause for different SQL dialects. ie, it's using `LIMIT` for mssql instead of `TOP`, or instead of `ROWNUM` for Oracle, etc. I think this could be due to us specifying the LIMIT statement in the example rows portion of `table_info`. So the LLM is seeing the `LIMIT` statement used in the prompt. Since we can't specify each dialect's method here, I think it's fine to just replace the `SELECT... LIMIT 3;` statement with `3 rows from table_name table:`, and wrap everything in a block comment directly following the `CREATE` statement. The Rajkumar et al paper wrapped the example rows and `SELECT` statement in a block comment as well anyway. Thoughts @fpingham?	2 years ago
Luis	562d9891ea	Add regex dict: (#1616 ) This class enables us to send a dictionary containing an output key and the expected format, which in turn allows us to retrieve the result of the matching formats and extract specific information from it. To exclude irrelevant information from our return dictionary, we can prompt the LLM to use a specific command that notifies us when it doesn't know the answer. We refer to this variable as the "no_update_value". Regarding the updated regular expression pattern (r"{}:\s?([^.'\n']).?"), it enables us to retrieve a format as 'Output Key':'value'. We have improved the regex by adding an optional space between ':' and 'value' with "s?", and by excluding points and line jumps from the matches using "[^.'\n']".	2 years ago

Harrison Chase	ec727bf166	Align table info (#999 ) (#1034 ) Currently the chain is getting the column names and types on the one side and the example rows on the other.

For an instantiation of this, please refer to the changes in the `sqlite.ipynb` notebook. Also changed `eval` for `ast.literal_eval` when interpreting the results from the sample row query since it is a better practice. --------- Co-authored-by: Francisco Ingham <> --------- Co-authored-by: Francisco Ingham <fpingham@gmail.com>	2 years ago

Jason Liu	54f9e4287f	Pass kwargs from initialize_agent into agent classmethod (#799 ) # Problem I noticed that in order to change the prefix of the prompt in the `zero-shot-react-description` agent we had to dig around to subset strings deep into the agent's attributes. It requires the user to inspect a long chain of attributes and classes. `initialize_agent -> AgentExecutor -> Agent -> LLMChain -> Prompt from Agent.create_prompt` ``` python agent = initialize_agent( tools=tools, llm=fake_llm, agent="zero-shot-react-description" ) prompt_str = agent.agent.llm_chain.prompt.template new_prompt_str = change_prefix(prompt_str) agent.agent.llm_chain.prompt.template = new_prompt_str ``` # Implemented Solution `initialize_agent` accepts `*kwargs` but passes it to `AgentExecutor` but not `ZeroShotAgent`, by simply giving the kwargs to the agent class methods we can support changing the prefix and suffix for one agent while allowing future agents to take advantage of `initialize_agent`. ``` agent = initialize_agent( tools=tools, llm=fake_llm, agent="zero-shot-react-description", agent_kwargs={"prefix": prefix, "suffix": suffix} ) ``` To be fair, this was before finding docs around custom agents here: https://langchain.readthedocs.io/en/latest/modules/agents/examples/custom_agent.html?highlight=custom%20#custom-llmchain but i find that my use case just needed to change the prefix a little. # Changes Pass kwargs to Agent class method * Added a test to check suffix and prefix --------- Co-authored-by: Jason Liu <jason@jxnl.coA>	2 years ago

Each part here has a "getting started", "how to", "key concepts" and "reference" section (except in a few select cases where it didnt easily fit). - Use Cases: this is to separate use cases (like summarization, question answering, evaluation, etc) from the modules, and provide a different entry point to the code base.

Andrew Gleave	ea67c049f0	Support SQL statements that return no results (#222 ) Adds support for statements such as insert, update etc which do not return any rows. `engine.execute` is deprecated and so execution has been updated to use `connection.exec_driver_sql` as-per: https://docs.sqlalchemy.org/en/14/core/connections.html#sqlalchemy.engine.Engine.execute	2 years ago
Akash Samant	d368c43648	Bug Fix (#221 ) Quick bug fix for semantic similarity vector injection	2 years ago
Harrison Chase	b94244eb12	nits (#210 ) use json.dump move test to integration tests (since it requires huggingface_hub)	2 years ago
Akash Samant	ae72cf84b8	Save Prompts (#194 )	2 years ago
Bagatur	b90e25f786	Add HuggingFace Hub Embeddings (#125 ) Add support for calling HuggingFace embedding models using the HuggingFaceHub Inference API. New class mirrors the existing HuggingFaceHub LLM implementation. Currently only supports 'sentence-transformers' models. Closes #86	2 years ago
Harrison Chase	6eab5254e5	add docs for custom agents (#196 )	2 years ago
Harrison Chase	08deed9002	Harrison/memory docs (#195 ) update memory docs and change variables	2 years ago
Harrison Chase	b913df3774	make attrs public (#187 ) since they are used outside of the class, should be public	2 years ago
Samantha Whitmore	a408ed3ea3	Samantha/add conversation chain (#166 ) Add MemoryChain and ConversationChain as chains that take a docstore in addition to the prompt, and use the docstore to stuff context into the prompt. This can be used to have an ongoing conversation with a chatbot. Probably needs a bit of refactoring for code quality Co-authored-by: Harrison Chase <hw.chase.17@gmail.com>	2 years ago
Harrison Chase	4334ffa6f9	Harrison/clean up language (#179 ) dynamic prompts are no longer a thing	2 years ago
Samantha Whitmore	09f301cd38	Add add_example method to all ExampleSelector classes, with tests (#178 ) Also updated docs, and noticed an issue with the add_texts method on VectorStores that I had missed before -- the metadatas arg should be required to match the classmethod which initializes the VectorStores (the add_example methods break otherwise in the ExampleSelectors)	2 years ago
Harrison Chase	d3a7429f61	(WIP) agents (#171 )	2 years ago
Harrison Chase	4a4dfbfbed	Harrison/sequential chains (#168 ) add support for basic sequential chains	2 years ago
Samantha Whitmore	315b0c09c6	wip: add method for both docstore and embeddings (#119 ) this will break atm but wanted to get thoughts on implementation. 1. should add() be on docstore interface? 2. should InMemoryDocstore change to take a list of documents as init? (makes this slightly easier to implement in FAISS -- if we think it is less clean then could expose a method to get the number of documents currently in the dict, and perform the logic of creating the necessary dictionary in the FAISS.add_texts method.

Edmar Ferreira	8a5ec894e7	Prompt from file proof of concept using plain text (#127 ) This is a simple proof of concept of using external files as templates. I'm still feeling my way around the codebase. As a user, I want to use files as prompts, so it will be easier to manage and test prompts. The future direction is to use a template engine, most likely Mako.	2 years ago
