Michael Landis	7047a2c1af	feat: add Momento as a standard cache and chat message history provider (#5221 ) # Add Momento as a standard cache and chat message history provider This PR adds Momento as a standard caching provider. Implements the interface, adds integration tests, and documentation. We also add Momento as a chat history message provider along with integration tests, and documentation. [Momento](https://www.gomomento.com/) is a fully serverless cache. Similar to S3 or DynamoDB, it requires zero configuration, infrastructure management, and is instantly available. Users sign up for free and get 50GB of data in/out for free every month. ## Before submitting ✅ We have added documentation, notebooks, and integration tests demonstrating usage.

Davis Chase	3be9ba14f3	OpenSearch top k parameter fix (#5216 ) For most queries it's the `size` parameter that determines final number of documents to return. Since our abstractions refer to this as `k`, set this to be `k` everywhere instead of expecting a separate param. Would be great to have someone more familiar with OpenSearch validate that this is reasonable (e.g. that having `size` and what OpenSearch calls `k` be the same won't lead to any strange behavior). cc @naveentatikonda Closes #5212	1 year ago

Jeff Vestal	0b542a9706	Add ElasticsearchEmbeddings class for generating embeddings using Elasticsearch models (#3401 ) This PR introduces a new module, `elasticsearch_embeddings.py`, which provides a wrapper around Elasticsearch embedding models. The new ElasticsearchEmbeddings class allows users to generate embeddings for documents and query texts using a [model deployed in an Elasticsearch cluster](https://www.elastic.co/guide/en/machine-learning/current/ml-nlp-model-ref.html#ml-nlp-model-ref-text-embedding). ### Main features: 1. The ElasticsearchEmbeddings class initializes with an Elasticsearch connection object and a model_id, providing an interface to interact with the Elasticsearch ML client through [infer_trained_model](https://elasticsearch-py.readthedocs.io/en/v8.7.0/api.html?highlight=trained%20model%20infer#elasticsearch.client.MlClient.infer_trained_model) . 2. The `embed_documents()` method generates embeddings for a list of documents, and the `embed_query()` method generates an embedding for a single query text. 3. The class supports custom input text field names in case the deployed model expects a different field name than the default `text_field`. 4. The implementation is compatible with any model deployed in Elasticsearch that generates embeddings as output. ### Benefits: 1. Simplifies the process of generating embeddings using Elasticsearch models. 2. Provides a clean and intuitive interface to interact with the Elasticsearch ML client. 3. Allows users to easily integrate Elasticsearch-generated embeddings.

Currently the Evernote loader concatenates the content of all notes in the export into a single document and only attaches the name of the export file as metadata on the document. This change ensures that each note is loaded as an independent document and all available metadata on the note e.g. author, title, created, updated are added as metadata on each document. It also uses an existing optional dependency of `html2text` instead of `pypandoc` to remove the need to download the pandoc application via `download_pandoc()` to be able to use the `pypandoc` python bindings.

Gengliang Wang	bf5a3c6dec	Support Databricks in SQLDatabase (#4702 ) This PR adds support for Databricks runtime and Databricks SQL by using [Databricks SQL Connector for Python](https://docs.databricks.com/dev-tools/python-sql-connector.html). As a cloud data platform, accessing Databricks requires a URL as follows `databricks://token:{api_token}@{hostname}?http_path={http_path}&catalog={catalog}&schema={schema}`. The URL is complicated and it may take users a while to figure it out. Since the fields `api_token`/`hostname`/`http_path` fields are known in the Databricks notebook, I am proposing a new method `from_databricks` to simplify the connection to Databricks. ## In Databricks Notebook After changes, Databricks users only need to specify the `catalog` and `schema` field when using langchain. <img width="881" alt="image" src="https://github.com/hwchase17/langchain/assets/1097932/984b4c57-4c2d-489d-b060-5f4918ef2f37"> ## In Jupyter Notebook The method can be used on the local setup as well: <img width="678" alt="image" src="https://github.com/hwchase17/langchain/assets/1097932/142e8805-a6ef-4919-b28e-9796ca31ef19">	1 year ago

It can connect to Spark via building a local/remote SparkSession. * Include a notebook example I tried some complicated queries (window function, table joins), and the tool works well. Compared to the [Spark Dataframe agent](https://python.langchain.com/en/latest/modules/agents/toolkits/examples/spark.html), this tool is able to generate queries across multiple tables. --------- # Your PR Title (What it does) <!-- Thank you for contributing to LangChain!

I like the Ecosystem term. It is more generic and semantically richer than the Integration term. But it mentally overloads users. The `integration` term is more concrete. UPDATE: after discussion, the Ecosystem is the term. Ecosystem/Integrations is the page (in place of Ecosystem/LongChain Ecosystem).

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. PR: I've created the `Tutorials` page (from the `Additional Resources/YouTube` page) and moved it to the top level of documentation in the `Getting Started` section. ## Who can review? @dev2049 NOTE: PR checks are randomly failing `3aefaafcdb` `258819eadf` `514d81b5b3`	1 year ago

Samuli Rauatmaa	66828ad231	add the existing OpenWeatherMap tool to the public api (#4292 ) [OpenWeatherMapAPIWrapper](`f70e18a5b3/docs/modules/agents/tools/examples/openweathermap.ipynb`) works wonderfully, but the _tool_ itself can't be used in master branch. - added OpenWeatherMap tool to the public api, to be loadable with `load_tools` by using "openweathermap-api" tool name (that name is used in the existing [docs](`aff33d52c5/docs/modules/agents/tools/getting_started.md`), at the bottom of the page) - updated OpenWeatherMap tool's description to make the input format match what the API expects (e.g. `London,GB` instead of `'London,GB'`) - added [ecosystem documentation page for OpenWeatherMap](`f9c41594fe/docs/ecosystem/openweathermap.md`) - added tool usage example to [OpenWeatherMap's notebook](`f9c41594fe/docs/modules/agents/tools/examples/openweathermap.ipynb`) Let me know if there's something I missed or something needs to be updated! Or feel free to make edits yourself if that makes it easier for you 🙂	1 year ago

Zander Chase	d85b04be7f	Add RELLM and JSONFormer experimental LLM decoding (#4185 ) [RELLM](https://github.com/r2d4/rellm) is a library that wraps local HuggingFace pipeline models for structured decoding. RELLM works by generating tokens one at a time. At each step, it masks tokens that don't conform to the provided partial regular expression. [JSONFormer](https://github.com/1rgs/jsonformer) is a bit different, where it sequentially adds the keys then decodes each value directly	1 year ago
