Jon Luo	0a1b1806e9	sql: do not hard code the LIMIT clause in the table_info section (#1563 ) Seeing a lot of issues in Discord in which the LLM is not using the correct LIMIT clause for different SQL dialects. ie, it's using `LIMIT` for mssql instead of `TOP`, or instead of `ROWNUM` for Oracle, etc. I think this could be due to us specifying the LIMIT statement in the example rows portion of `table_info`. So the LLM is seeing the `LIMIT` statement used in the prompt. Since we can't specify each dialect's method here, I think it's fine to just replace the `SELECT... LIMIT 3;` statement with `3 rows from table_name table:`, and wrap everything in a block comment directly following the `CREATE` statement. The Rajkumar et al paper wrapped the example rows and `SELECT` statement in a block comment as well anyway. Thoughts @fpingham?	2 years ago
Tim Asp	b3234bf3b0	cleanup: unify 3 different pdf loaders, rename PagedPDFSplitter (#1615 ) `OnlinePDFLoader` and `PagedPDFSplitter` lived separate from the rest of the pdf loaders. Because they're all similar, I propose moving all to `pdy.py` and the same docs/examples page. Additionally, `PagedPDFSplitter` naming doesn't match the pattern the rest of the loaders follow, so I renamed to `PyPDFLoader` and had it inherit from `BasePDFLoader` so it can now load from remote file sources.	2 years ago
Luis	562d9891ea	Add regex dict: (#1616 ) This class enables us to send a dictionary containing an output key and the expected format, which in turn allows us to retrieve the result of the matching formats and extract specific information from it. To exclude irrelevant information from our return dictionary, we can prompt the LLM to use a specific command that notifies us when it doesn't know the answer. We refer to this variable as the "no_update_value". Regarding the updated regular expression pattern (r"{}:\s?([^.'\n']).?"), it enables us to retrieve a format as 'Output Key':'value'. We have improved the regex by adding an optional space between ':' and 'value' with "s?", and by excluding points and line jumps from the matches using "[^.'\n']".	2 years ago

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

Naveen Tatikonda	0118706fd6	Add Support for OpenSearch Vector database (#1191 ) ### Description This PR adds a wrapper which adds support for the OpenSearch vector database. Using opensearch-py client we are ingesting the embeddings of given text into opensearch cluster using Bulk API. We can perform the `similarity_search` on the index using the 3 popular searching methods of OpenSearch k-NN plugin: - `Approximate k-NN Search` use approximate nearest neighbor (ANN) algorithms from the [nmslib](https://github.com/nmslib/nmslib), [faiss](https://github.com/facebookresearch/faiss), and [Lucene](https://lucene.apache.org/) libraries to power k-NN search. - `Script Scoring` extends OpenSearch’s script scoring functionality to execute a brute force, exact k-NN search. - `Painless Scripting` adds the distance functions as painless extensions that can be used in more complex combinations. Also, supports brute force, exact k-NN search like Script Scoring. ### Issues Resolved https://github.com/hwchase17/langchain/issues/1054 --------- Signed-off-by: Naveen Tatikonda <navtat@amazon.com>	2 years ago

Yes. Follow up: Who is the reigning men's U.S. Open champion? Intermediate answer: Current champions Carlos Alcaraz, 2022 men's singles champion. Follow up: Where is Carlos Alcaraz from?

Harrison Chase	ec727bf166	Align table info (#999 ) (#1034 ) Currently the chain is getting the column names and types on the one side and the example rows on the other. It is easier for the llm to read the table information if the column name and examples are shown together so that it can easily understand to which columns do the examples refer to. For an instantiation of this, please refer to the changes in the `sqlite.ipynb` notebook. Also changed `eval` for `ast.literal_eval` when interpreting the results from the sample row query since it is a better practice. --------- Co-authored-by: Francisco Ingham <> --------- Co-authored-by: Francisco Ingham <fpingham@gmail.com>	2 years ago
