Tom	e533da8bf2	Adding Marqo to vectorstore ecosystem (#7068 ) This PR brings in a vectorstore interface for [Marqo](https://www.marqo.ai/). The Marqo vectorstore exposes some of Marqo's functionality in addition the the VectorStore base class. The Marqo vectorstore also makes the embedding parameter optional because inference for embeddings is an inherent part of Marqo. Docs, notebook examples and integration tests included.

Feras Almannaa	79b59a8e06	optimize pgvector `add_texts` (#7185 ) - Description: At the moment, inserting new embeddings to pgvector is querying all embeddings every time as the defined `embeddings` relationship is using the default params, which sets `lazy="select"`. This change drastically improves the performance and adds a few additional cleanups: * remove `collection.embeddings.append` as it was querying all embeddings on insert, replace with `collection_id` param * centralize storing logic in add_embeddings function to reduce duplication * remove boilerplate - Issue: No issue was opened. - Dependencies: None. - Tag maintainer: this is a vectorstore update, so I think @rlancemartin, @eyurtsev - Twitter handle: @falmannaa	1 year ago

Richy Wang	cab7d86f23	Implement delete interface of vector store on AnalyticDB (#7170 ) Hi, there This pull request contains two commit: 1. Implement delete interface with optional ids parameter on AnalyticDB. 2. Allow customization of database connection behavior by exposing engine_args parameter in interfaces. - This commit adds the `engine_args` parameter to the interfaces, allowing users to customize the behavior of the database connection. The `engine_args` parameter accepts a dictionary of additional arguments that will be passed to the create_engine function. Users can now modify various aspects of the database connection, such as connection pool size and recycle time. This enhancement provides more flexibility and control to users when interacting with the database through the exposed interfaces. This commit is related to VectorStores @rlancemartin @eyurtsev Thank you for your attention and consideration.	1 year ago

Jamal	a2f191a322	Replace JIRA Arbitrary Code Execution vulnerability with finer grain API wrapper (#6992 ) This fixes #4833 and the critical vulnerability https://nvd.nist.gov/vuln/detail/CVE-2023-34540 Previously, the JIRA API Wrapper had a mode that simply pipelined user input into an `exec()` function. [The intended use of the 'other' mode is to cover any of Atlassian's API that don't have an existing interface](`cc33bde74f/langchain/tools/jira/prompt.py (L24)`) Fortunately all of the [Atlassian JIRA API methods are subfunctions of their `Jira` class](https://atlassian-python-api.readthedocs.io/jira.html), so this implementation calls these subfunctions directly. As well as passing a string representation of the function to call, the implementation flexibly allows for optionally passing args and/or keyword-args. These are given as part of the dictionary input. Example: ``` { "function": "update_issue_field", #function to execute "args": [ #list of ordered args similar to other examples in this JiraAPIWrapper "key", {"summary": "New summary"} ], "kwargs": {} #dict of key value keyword-args pairs } ``` the above is equivalent to `self.jira.update_issue_field("key", {"summary": "New summary"})` Alternate query schema designs are welcome to make querying easier without passing and evaluating arbitrary python code. I considered parsing (without evaluating) input python code and extracting the function, args, and kwargs from there and then pipelining them into the callable function via `f(args, *kwargs)` - but this seemed more direct. @vowelparrot @dev2049 --------- Co-authored-by: Jamal Rahman <jamal.rahman@builder.ai>	1 year ago

Leonid Ganeline	ecee4d6e92	docs: update `youtube` videos and tutorials (#6515 ) added tutorials.mdx; updated youtube.mdx Rationale: the Tutorials section in the documentation is top-priority. (for example, https://pytorch.org/docs/stable/index.html) Not every project has resources to make tutorials. We have such a privilege. Community experts created several tutorials on YouTube. But the tutorial links are now hidden on the YouTube page and not easily discovered by first-time visitors. - Added new videos and tutorials that were created since the last update. - Made some reprioritization between videos on the base of the view numbers. #### Who can review? - @hwchase17 - @dev2049	1 year ago

wewebber-merlin	8a7c95e555	Retryable exception for empty OpenAI embedding. (#7070 ) Description: The OpenAI "embeddings" API intermittently falls into a failure state where an embedding is returned as [ Nan ], rather than the expected 1536 floats. This patch checks for that state (specifically, for an embedding of length 1) and if it occurs, throws an ApiError, which will cause the chunk to be retried. Issue: I have been unable to find an official langchain issue for this problem, but it is discussed (by another user) at https://stackoverflow.com/questions/76469415/getting-embeddings-of-length-1-from-langchain-openaiembeddings Maintainer: @dev2049 Testing: Since this is an intermittent OpenAI issue, I have not provided a unit or integration test. The provided code has, though, been run successfully over several million tokens. --------- Co-authored-by: William Webber <william@williamwebber.com> Co-authored-by: Harrison Chase <hw.chase.17@gmail.com>	1 year ago
