Filip Michalsky	49593a3e41	Notebook example: Context-Aware AI Sales Agent (#3547 ) I would like to contribute with a jupyter notebook example implementation of an AI Sales Agent using `langchain`. The bot understands the conversation stage (you can define your own stages fitting your needs) using two chains: 1. StageAnalyzerChain - takes context and LLM decides what part of sales conversation is one in 2. SalesConversationChain - generate next message Schema: https://images-genai.s3.us-east-1.amazonaws.com/architecture2.png my original repo: https://github.com/filip-michalsky/SalesGPT This example creates a sales person named Ted Lasso who is trying to sell you mattresses. Happy to update based on your feedback. Thanks, Filip https://twitter.com/FilipMichalsky	1 year ago

mbchang	628e93a9a0	docs: simplification of two agent d&d simulation (#3550 ) Simplifies the [Two Agent D&D](https://python.langchain.com/en/latest/use_cases/agent_simulations/two_player_dnd.html) example with a cleaner, simpler interface that is extensible for multiple agents. `DialogueAgent`: - `send()`: applies the chatmodel to the message history and returns the message string - `receive(name, message)`: adds the `message` spoken by `name` to message history The `DialogueSimulator` class takes a list of agents. At each step, it performs the following: 1. Select the next speaker 2. Calls the next speaker to send a message 3. Broadcasts the message to all other agents 4. Update the step counter. The selection of the next speaker can be implemented as any function, but in this case we simply loop through the agents.	1 year ago
apurvsibal	af7906f100	Update Alchemy Key URL (#3559 ) Update Alchemy Key URL in Blockchain Document Loader. I want to say thank you for the incredible work the LangChain library creators have done. I am amazed at how seamlessly the Loader integrates with Ethereum Mainnet, Ethereum Testnet, Polygon Mainnet, and Polygon Testnet, and I am excited to see how this technology can be extended in the future. @hwchase17 - Please let me know if I can improve or if I have missed any community guidelines in making the edit? Thank you again for your hard work and dedication to the open source community.	1 year ago

To simulate this game, we create a `TwoAgentSimulator` class that coordinates the dialogue between the two agents.	1 year ago

Sami Liedes	c8b70e1c6a	langchain-server: Do not expose postgresql port to host (#3431 ) Apart from being unnecessary, postgresql is run on its default port, which means that the langchain-server will fail to start if there is already a postgresql server running on the host. This is obviously less than ideal. (Yeah, I don't understand why "expose" is the syntax that does not expose the ports to the host...) Tested by running langchain-server and trying out debugging on a host that already has postgresql bound to the port 5432. Co-authored-by: Sami Liedes <sami.liedes@rocket-science.ch>	1 year ago

Lucas Vieira	e6c1c32aff	Support GCS Objects with `/` in GCS Loaders (#3356 ) So, this is basically fixing the same things as #1517 but for GCS. ### Problem When loading GCS Objects with `/` in the object key (eg. folder/some-document.txt) using `GCSFileLoader`, the objects are downloaded into a temporary directory and saved as a file. This errors out when the parent directory does not exist within the temporary directory. ### What this pr does Creates parent directories based on object key. This also works with deeply nested keys: folder/subfolder/some-document.txt	1 year ago

killpanda	344e3508b1	bug_fixes: use md5 instead of uuid id generation (#3442 ) At present, the method of generating `point` in qdrant is to use random `uuid`. The problem with this approach is that even documents with the same content will be inserted repeatedly instead of updated. Using `md5` as the `ID` of `point` to insert text can achieve true `update or insert`. Co-authored-by: mayue <mayue05@qiyi.com>	1 year ago

Felipe Lopes	8c56e92566	feat: add private weaviate api_key support on from_texts (#3139 ) This PR adds support for providing a Weaviate API Key to the VectorStore methods `from_documents` and `from_texts`. With this addition, users can authenticate to Weaviate and make requests to private Weaviate servers when using these methods. ## Motivation Currently, LangChain's VectorStore methods do not provide a way to authenticate to Weaviate. This limits the functionality of the library and makes it more difficult for users to take advantage of Weaviate's features. This PR addresses this issue by adding support for providing a Weaviate API Key as extra parameter used in the `from_texts` method. ## Contributing Guidelines I have read the [contributing guidelines](`72b7d76d79/.github/CONTRIBUTING.md`) and the PR code passes the following tests: - [x] make format - [x] make lint - [x] make coverage - [x] make test	1 year ago
