Mike McGarry	ddd595fe81	feature/4493 Improve Evernote Document Loader (#4577 ) # Improve Evernote Document Loader When exporting from Evernote you may export more than one note. 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.

Eugene Yurtsev	0ff59569dc	Adds 'IN' metadata filter for pgvector for checking set presence (#4982 ) # Adds "IN" metadata filter for pgvector to all checking for set presence PGVector currently supports metadata filters of the form: ``` {"filter": {"key": "value"}} ``` which will return documents where the "key" metadata field is equal to "value". This PR adds support for metadata filters of the form: ``` {"filter": {"key": { "IN" : ["list", "of", "values"]}}} ``` Other vector stores support this via an "$in" syntax. I chose to use "IN" to match postgres' syntax, though happy to switch.

Interestingly, gpt3.5-turbo needed the examples=DEFAULT_FEWSHOT_EXAMPLES to write consistent DAX queries, so gpt4 seems necessary as the smart llm. Fixes #4325 ## Before submitting Azure-core and Azure-identity are necessary dependencies check integration tests with the following: `pytest tests/integration_tests/utilities/test_powerbi_api.py` `pytest tests/integration_tests/agent/test_powerbi_agent.py` You will need a power bi account with a dataset id + table name in order to test.

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

Chakib Ben Ziane	5525b704cc	Chatconv agent: output parser exception (#4923 ) the output parser form chat conversational agent now raises `OutputParserException` like the rest. The `raise OutputParserExeption(...) from e` form also carries through the original error details on what went wrong. I added the `ValueError` as a base class to `OutputParserException` to avoid breaking code that was relying on `ValueError` as a way to catch exceptions from the agent. So catching ValuError still works. Not sure if this is a good idea though ?	1 year ago

Leonid Ganeline	e2d7677526	docs: compound ecosystem and integrations (#4870 ) # Docs: compound ecosystem and integrations Problem statement: We have a big overlap between the References/Integrations and Ecosystem/LongChain Ecosystem pages. It confuses users. It creates a situation when new integration is added only on one of these pages, which creates even more confusion. - removed References/Integrations page (but move all its information into the individual integration pages - in the next PR). - renamed Ecosystem/LongChain Ecosystem into Integrations/Integrations. 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). As a result, a user gets a single place to start with the individual integration.	1 year ago

Richard He	7642f2159c	Add human message as input variable to chat agent prompt creation (#4542 ) # Add human message as input variable to chat agent prompt creation This PR adds human message and system message input to `CHAT_ZERO_SHOT_REACT_DESCRIPTION` agent, similar to [conversational chat agent](`7bcf238a1a/langchain/agents/conversational_chat/base.py (L64-L71)`). I met this issue trying to use `create_prompt` function when using the [BabyAGI agent with tools notebook](https://python.langchain.com/en/latest/use_cases/autonomous_agents/baby_agi_with_agent.html), since BabyAGI uses “task” instead of “input” input variable. For normal zero shot react agent this is fine because I can manually change the suffix to “{input}/n/n{agent_scratchpad}” just like the notebook, but I cannot do this with conversational chat agent, therefore blocking me to use BabyAGI with chat zero shot agent. I tested this in my own project [Chrome-GPT](https://github.com/richardyc/Chrome-GPT) and this fix worked. ## Request for review Agents / Tools / Toolkits - @vowelparrot	1 year ago
