bair82	ae5695ad32	Update cohere.py (#795) ... When stop tokens are set in Cohere LLM constructor, they are currently not stripped from the response, and they should be stripped	1 year ago
Johanna Appel	cacf4091c0	Fix documentation for 'model' parameter in CohereEmbeddings (#797) ... Currently, the class parameter 'model_name' of the CohereEmbeddings class is not supported, but 'model' is. The class documentation is inconsistent with this, though, so I propose to either fix the documentation (this PR right now) or fix the parameter. It will create the following error: ``` ValidationError: 1 validation error for CohereEmbeddings model_name extra fields not permitted (type=value_error.extra) ```	1 year 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>	1 year ago
Roger Zurawicki	c331009440	docs: Update langchain link to PyPI (#800) ... Simple one-line fix CONTRIBUTING used a link that pointed to the `ruff` project.	1 year ago
Roy Williams	6086292252	Centralize logic for loading from LangChainHub, add ability to pin dependencies (#805) ... It's generally considered to be a good practice to pin dependencies to prevent surprise breakages when a new version of a dependency is released. This commit adds the ability to pin dependencies when loading from LangChainHub. Centralizing this logic and using urllib fixes an issue identified by some windows users highlighted in this video - https://youtu.be/aJ6IQUh8MLQ?t=537	1 year ago

Harrison Chase	248c297f1b	Sample row in table info for SQLDatabase (#769) (#782) ... The agents usually benefit from understanding what the data looks like to be able to filter effectively. Sending just one row in the table info allows the agent to understand the data before querying and get better results. --------- Co-authored-by: Francisco Ingham <> --------- Co-authored-by: Francisco Ingham <fpingham@gmail.com>	1 year ago

Francisco Ingham	374e510f94	Upper bound on number of iterations (#754) ... Some custom agents might continue to iterate until they find the correct answer, getting stuck on loops that generate request after request and are really expensive for the end user. Putting an upper bound for the number of iterations by default controls this and can be explicitly tweaked by the user if necessary. Co-authored-by: Francisco Ingham <>	1 year ago
Smit Shah	28efbb05bf	Add params to reduce K dynamically to reduce it below token limit (#739) ... Referring to #687, I implemented the functionality to reduce K if it exceeds the token limit. Edit: I should have ran make lint locally. Also, this only applies to `StuffDocumentChain`	1 year ago
