Matt Robinson	bf3f554357	feat: batch multiple files in a single Unstructured API request (#4525 ) ### Submit Multiple Files to the Unstructured API Enables batching multiple files into a single Unstructured API requests. Support for requests with multiple files was added to both `UnstructuredAPIFileLoader` and `UnstructuredAPIFileIOLoader`. Note that if you submit multiple files in "single" mode, the result will be concatenated into a single document. We recommend using this feature in "elements" mode. ### Testing The following should load both documents, using two of the example docs from the integration tests folder. ```python from langchain.document_loaders import UnstructuredAPIFileLoader file_paths = ["examples/layout-parser-paper.pdf", "examples/whatsapp_chat.txt"] loader = UnstructuredAPIFileLoader( file_paths=file_paths, api_key="FAKE_API_KEY", strategy="fast", mode="elements", ) docs = loader.load() ```	1 year ago

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.

Eugene Yurtsev	06e524416c	power bi api wrapper integration tests & bug fix (#4983 ) # Powerbi API wrapper bug fix + integration tests - Bug fix by removing `TYPE_CHECKING` in in utilities/powerbi.py - Added integration test for power bi api in utilities/test_powerbi_api.py - Added integration test for power bi agent in agent/test_powerbi_agent.py - Edited .env.examples to help set up power bi related environment variables - Updated demo notebook with working code in docs../examples/powerbi.ipynb - AzureOpenAI -> ChatOpenAI Notes: Chat models (gpt3.5, gpt4) are much more capable than davinci at writing DAX queries, so that is important to getting the agent to work properly. Interestingly, gpt3.5-turbo needed the examples=DEFAULT_FEWSHOT_EXAMPLES to write consistent DAX queries, so gpt4 seems necessary as the smart llm.

Li Yuanzheng	3b6206af49	Respect User-Specified User-Agent in WebBaseLoader (#4579 ) # Respect User-Specified User-Agent in WebBaseLoader This pull request modifies the `WebBaseLoader` class initializer from the `langchain.document_loaders.web_base` module to preserve any User-Agent specified by the user in the `header_template` parameter. Previously, even if a User-Agent was specified in `header_template`, it would always be overridden by a random User-Agent generated by the `fake_useragent` library. With this change, if a User-Agent is specified in `header_template`, it will be used. Only in the case where no User-Agent is specified will a random User-Agent be generated and used. This provides additional flexibility when using the `WebBaseLoader` class, allowing users to specify their own User-Agent if they have a specific need or preference, while still providing a reasonable default for cases where no User-Agent is specified. This change has no impact on existing users who do not specify a User-Agent, as the behavior in this case remains the same. However, for users who do specify a User-Agent, their choice will now be respected and used for all subsequent requests made using the `WebBaseLoader` class.

Prerit Das	2747ccbcf1	Allow custom base Zapier prompt (#4213 ) Currently, all Zapier tools are built using the pre-written base Zapier prompt. These small changes (that retain default behavior) will allow a user to create a Zapier tool using the ZapierNLARunTool while providing their own base prompt. Their prompt must contain input fields for zapier_description and params, checked and enforced in the tool's root validator. An example of when this may be useful: user has several, say 10, Zapier tools enabled. Currently, the long generic default Zapier base prompt is attached to every single tool, using an extreme number of tokens for no real added benefit (repeated). User prompts LLM on how to use Zapier tools once, then overrides the base prompt. Or: user has a few specific Zapier tools and wants to maximize their success rate. So, user writes prompts/descriptions for those tools specific to their use case, and provides those to the ZapierNLARunTool. A consideration - this is the simplest way to implement this I could think of... though ideally custom prompting would be possible at the Toolkit level as well. For now, this should be sufficient in solving the concerns outlined above.	1 year ago

Zander Chase	0c6ed657ef	Convert Chain to a Chain Factory (#4605 ) ## Change Chain argument in client to accept a chain factory The `run_over_dataset` functionality seeks to treat each iteration of an example as an independent trial. Chains have memory, so it's easier to permit this type of behavior if we accept a factory method rather than the chain object directly. There's still corner cases / UX pains people will likely run into, like: - Caching may cause issues - if memory is persisted to a shared object (e.g., same redis queue) , this could impact what is retrieved - If we're running the async methods with concurrency using local models, if someone naively instantiates the chain and loads each time, it could lead to tons of disk I/O or OOM	1 year ago

Evan Jones	f668251948	parameterized distance metrics; lint; format; tests (#4375 ) # Parameterize Redis vectorstore index Redis vectorstore allows for three different distance metrics: `L2` (flat L2), `COSINE`, and `IP` (inner product). Currently, the `Redis._create_index` method hard codes the distance metric to COSINE. I've parameterized this as an argument in the `Redis.from_texts` method -- pretty simple. Fixes #4368 ## Before submitting I've added an integration test showing indexes can be instantiated with all three values in the `REDIS_DISTANCE_METRICS` literal. An example notebook seemed overkill here. Normal API documentation would be more appropriate, but no standards are in place for that yet. ## Who can review? Not sure who's responsible for the vectorstore module... Maybe @eyurtsev / @hwchase17 / @agola11 ?	1 year ago

Eugene Yurtsev	2ceb807da2	Add PDF parser implementations (#4356 ) # Add PDF parser implementations This PR separates the data loading from the parsing for a number of existing PDF loaders. Parser tests have been designed to help encourage developers to create a consistent interface for parsing PDFs. This interface can be made more consistent in the future by adding information into the initializer on desired behavior with respect to splitting by page etc. This code is expected to be backwards compatible -- with the exception of a bug fix with pymupdf parser which was returning `bytes` in the page content rather than strings. Also changing the lazy parser method of document loader to return an Iterator rather than Iterable over documents. ## Before submitting <!-- If you're adding a new integration, include an integration test and an example notebook showing its use! --> ## Who can review?
