Jari Bakken	3df2d831f9	Fix get_num_tokens for Anthropic models (#4911 ) The Anthropic classes used `BaseLanguageModel.get_num_tokens` because of an issue with multiple inheritance. Fixed by moving the method from `_AnthropicCommon` to both its subclasses. This change will significantly speed up token counting for Anthropic users.	1 year ago

Chakib Ben Ziane	5525b704cc	Chatconv agent: output parser exception (#4923 ) the output parser form chat conversational agent now raises `OutputParserException` like the rest. The `raise OutputParserExeption(...) from e` form also carries through the original error details on what went wrong. I added the `ValueError` as a base class to `OutputParserException` to avoid breaking code that was relying on `ValueError` as a way to catch exceptions from the agent. So catching ValuError still works. Not sure if this is a good idea though ?	1 year ago

Leonid Ganeline	e2d7677526	docs: compound ecosystem and integrations (#4870 ) # Docs: compound ecosystem and integrations Problem statement: We have a big overlap between the References/Integrations and Ecosystem/LongChain Ecosystem pages. It confuses users. It creates a situation when new integration is added only on one of these pages, which creates even more confusion. - removed References/Integrations page (but move all its information into the individual integration pages - in the next PR). - renamed Ecosystem/LongChain Ecosystem into Integrations/Integrations. I like the Ecosystem term. It is more generic and semantically richer than the Integration term. But it mentally overloads users. The `integration` term is more concrete. UPDATE: after discussion, the Ecosystem is the term. Ecosystem/Integrations is the page (in place of Ecosystem/LongChain Ecosystem). As a result, a user gets a single place to start with the individual integration.	1 year ago

Richard He	7642f2159c	Add human message as input variable to chat agent prompt creation (#4542 ) # Add human message as input variable to chat agent prompt creation This PR adds human message and system message input to `CHAT_ZERO_SHOT_REACT_DESCRIPTION` agent, similar to [conversational chat agent](`7bcf238a1a/langchain/agents/conversational_chat/base.py (L64-L71)`). I met this issue trying to use `create_prompt` function when using the [BabyAGI agent with tools notebook](https://python.langchain.com/en/latest/use_cases/autonomous_agents/baby_agi_with_agent.html), since BabyAGI uses “task” instead of “input” input variable. For normal zero shot react agent this is fine because I can manually change the suffix to “{input}/n/n{agent_scratchpad}” just like the notebook, but I cannot do this with conversational chat agent, therefore blocking me to use BabyAGI with chat zero shot agent. I tested this in my own project [Chrome-GPT](https://github.com/richardyc/Chrome-GPT) and this fix worked. ## Request for review Agents / Tools / Toolkits - @vowelparrot	1 year ago

They can be mixed with any classes from the "Text Splitters", so it is a different classification. ## Who can review? @hwchase17 - project lead @eyurtsev @vowelparrot NOTE: please, check out the results of the `Python code` text splitter example (text_splitters/examples/python.ipynb).

Ryan Culligan	6a9cdc43f5	Fix TypeError in Vectorstore Redis class methods (#4857 ) # Fix TypeError in Vectorstore Redis class methods This change resolves a TypeError that was raised when invoking the `from_texts_return_keys` method from the `from_texts` method in the `Redis` class. The error was due to the `cls` argument being passed explicitly, which led to it being provided twice since it's also implicitly passed in class methods. No relevant tests were added as the issue appeared to be better suited for linters to catch proactively. Changes: - Removed `cls=cls` from the call to `from_texts_return_keys` in the `from_texts` method. Related to: https://github.com/hwchase17/langchain/pull/4653	1 year ago
