yakigac	acd86d33bc	Add read only shared memory (#1491 ) Provide shared memory capability for the Agent. Inspired by #1293 . ## Problem If both Agent and Tools (i.e., LLMChain) use the same memory, both of them will save the context. It can be annoying in some cases. ## Solution Create a memory wrapper that ignores the save and clear, thereby preventing updates from Agent or Tools.	2 years ago

Tim Asp	01a57198b8	[bugfix] Fix persisted chromadb vectorstore (#1444 ) If a `persist_directory` param was set, chromadb would throw a warning that ""No embedding_function provided, using default embedding function: SentenceTransformerEmbeddingFunction". and would error with a `Illegal instruction: 4` error. This is on a MBP M1 13.2.1, python 3.9. I'm not entirely sure why that error happened, but when using `get_or_create_collection` instead of `list_collection` on our end, the error and warning goes away and chroma works as expected. Added bonus this is cleaner and likely more efficient. `list_collections` builds a new `Collection` instance for each collect, then `Chroma` would just use the `name` field to tell if the collection existed.	2 years ago

Zach Schillaci	cdb97f3dfb	Add Wikipedia search utility and tool (#1561 ) The Python `wikipedia` package gives easy access for searching and fetching pages from Wikipedia, see https://pypi.org/project/wikipedia/.

Felix Altenberger	b44c8bd969	Add optional `base_url` arg to `GitbookLoader` (#1552 ) First of all, big kudos on what you guys are doing, langchain is enabling some really amazing usecases and I'm having lot's of fun playing around with it. It's really cool how many data sources it supports out of the box. However, I noticed some limitations of the current `GitbookLoader` which this PR adresses: The main change is that I added an optional `base_url` arg to `GitbookLoader`. This enables use cases where one wants to crawl docs from a start page other than the index page, e.g., the following call would scrape all pages that are reachable via nav bar links from "https://docs.zenml.io/v/0.35.0": ```python GitbookLoader( web_page="https://docs.zenml.io/v/0.35.0", load_all_paths=True, base_url="https://docs.zenml.io", ) ``` Previously, this would fail because relative links would be of the form `/v/0.35.0/...` and the full link URLs would become `docs.zenml.io/v/0.35.0/v/0.35.0/...`. I also fixed another issue of the `GitbookLoader` where the link URLs were constructed incorrectly as `website//relative_url` if the provided `web_page` had a trailing slash.	2 years ago

Graham Neubig	31303d0b11	Added other evaluation metrics for data-augmented QA (#1521 ) This PR adds additional evaluation metrics for data-augmented QA, resulting in a report like this at the end of the notebook: ![Screen Shot 2023-03-08 at 8 53 23 AM](https://user-images.githubusercontent.com/398875/223731199-8eb8e77f-5ff3-40a2-a23e-f3bede623344.png) The score calculation is based on the [Critique](https://docs.inspiredco.ai/critique/) toolkit, an API-based toolkit (like OpenAI) that has minimal dependencies, so it should be easy for people to run if they choose. The code could further be simplified by actually adding a chain that calls Critique directly, but that probably should be saved for another PR if necessary.

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
