Florian Leuerer	64c6435545	Added client_settings support for chromadb vecstore (#1528 ) # Problem The ChromaDB vecstore only supported local connection. There was no way to use a chromadb server. # Fix Added `client_settings` as Chroma attribute. # Usage ``` from chromadb.config import Settings from langchain.vectorstores import Chroma chroma_settings = Settings(chroma_api_impl="rest", chroma_server_host="localhost", chroma_server_http_port="80") docsearch = Chroma.from_documents(chunks, embeddings, metadatas=metadatas, client_settings=chroma_settings, collection_name=COLLECTION_NAME) ```	2 years ago

Alpri Else	784d24a1d5	Support S3 Object keys with `/` in `S3FileLoader` (#1517 ) Resolves https://github.com/hwchase17/langchain/issues/1510 ### Problem When loading S3 Objects with `/` in the object key (eg. `folder/some-document.txt`) using `S3FileLoader`, 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. See https://github.com/hwchase17/langchain/issues/1510#issuecomment-1459583696 on how to reproduce this bug ### What this pr does Creates parent directories based on object key. This also works with deeply nested keys: `folder/subfolder/some-document.txt`	2 years ago

Ivan	97e3666e0d	changed requests.run to requests.get (#1485 ) This pull request proposes an update to the Lightweight wrapper library's documentation. The current documentation provides an example of how to use the library's requests.run method, as follows: requests.run("https://www.google.com"). However, this example does not work for the 0.0.102 version of the library. Testing: The changes have been tested locally to ensure they are working as intended. Thank you for considering this pull request.	2 years ago

Juanky Soriano	dec3750875	Change method to calculate number of tokens for OpenAIChat (#1457 ) Solves https://github.com/hwchase17/langchain/issues/1412 Currently `OpenAIChat` inherits the way it calculates the number of tokens, `get_num_token`, from `BaseLLM`. In the other hand `OpenAI` inherits from `BaseOpenAI`. `BaseOpenAI` and `BaseLLM` uses different methodologies for doing this. The first relies on `tiktoken` while the second on `GPT2TokenizerFast`. The motivation of this PR is: 1. Bring consistency about the way of calculating number of tokens `get_num_token` to the `OpenAI` family, regardless of `Chat` vs `non Chat` scenarios. 2. Give preference to the `tiktoken` method as it's serverless friendly. It doesn't require downloading models which might make it incompatible with `readonly` filesystems.	2 years ago

Kentaro Tanaka	6a4ee07e4f	Fix type hint of 'vectorstore_cls' arg in `SemanticSimilarityExampleSelector` (#1427 ) Hello! Thank you for the amazing library you've created! While following the tutorial at [the link(`Using an example selector`)](https://langchain.readthedocs.io/en/latest/modules/prompts/examples/few_shot_examples.html#using-an-example-selector), I noticed that passing Chroma as an argument to from_examples results in a type hint error. Error message(mypy): ``` Argument 3 to "from_examples" of "SemanticSimilarityExampleSelector" has incompatible type "Type[Chroma]"; expected "VectorStore" [arg-type]mypy(error) ``` This pull request fixes the type hint and allows the VectorStore class to be specified as an argument.	2 years ago

Jon Luo	882f7964fb	fix sql misinterpretation of % in query (#1408 ) % is being misinterpreted by sqlalchemy as parameter passing, so any `LIKE 'asdf%'` will result in a value error with mysql, mariadb, and maybe some others. This is one way to fix it - the alternative is to simply double up %, like `LIKE 'asdf%%'` but this seemed cleaner in terms of output. Fixes #1383	2 years ago

Eugene Yurtsev	a83a371069	Minor documentation update in initialize_agent (#1397 ) Updating documentation in initialize_agent. One thing that could benefit from further clarification is the responsibility breakdown by between an AgentExecutor vs. an Agent. The documentation for an AgentExecutor does not clarify that. From the class attributes, it appears that executor has access to the tools, while the agent is only aware of the tool names. Anyway, additional clarification would be beneficial on the AgentExecutor class.	2 years ago

Kacper Łukawski	8947797250	Return Cohere embeddings as lists of floats (#1394 ) This PR fixes the types returned by Cohere embeddings. Currently, Cohere client returns instances of `cohere.embeddings.Embeddings`. Since the transport layer relies on JSON, some numbers might be represented as ints, not floats, which happens quite often. While that doesn't seem to be an issue, it breaks some pydantic models if they require strict floats.	2 years ago
Jason Gill	1989e7d4c2	Update examples to prevent confusing missing _type warning (#1391 ) The YAML and JSON examples of prompt serialization now give a strange `No '_type' key found, defaulting to 'prompt'` message when you try to run them yourself or copy the format of the files. The reason for this harmless warning is that the _type key was not in the config files, which means they are parsed as a standard prompt. This could be confusing to new users (like it was confusing to me after upgrading from 0.0.85 to 0.0.86+ for my few_shot prompts that needed a _type added to the example_prompt config), so this update includes the _type key just for clarity. Obviously this is not critical as the warning is harmless, but it could be confusing to track down or be interpreted as an error by a new user, so this update should resolve that.	2 years ago
