Kacper Łukawski	f93d256190	Feat: Add batching to Qdrant (#5443 ) # Add batching to Qdrant Several people requested a batching mechanism while uploading data to Qdrant. It is important, as there are some limits for the maximum size of the request payload, and without batching implemented in Langchain, users need to implement it on their own. This PR exposes a new optional `batch_size` parameter, so all the documents/texts are loaded in batches of the expected size (64, by default). The integration tests of Qdrant are extended to cover two cases: 1. Documents are sent in separate batches. 2. All the documents are sent in a single request.	1 year ago

Martin Holecek	44b48d9518	Fix update_document function, add test and documentation. (#5359 ) # Fix for `update_document` Function in Chroma ## Summary This pull request addresses an issue with the `update_document` function in the Chroma class, as described in [#5031](https://github.com/hwchase17/langchain/issues/5031#issuecomment-1562577947). The issue was identified as an `AttributeError` raised when calling `update_document` due to a missing corresponding method in the `Collection` object. This fix refactors the `update_document` method in `Chroma` to correctly interact with the `Collection` object. ## Changes 1. Fixed the `update_document` method in the `Chroma` class to correctly call methods on the `Collection` object. 2. Added the corresponding test `test_chroma_update_document` in `tests/integration_tests/vectorstores/test_chroma.py` to reflect the updated method call. 3. Added an example and explanation of how to use the `update_document` function in the Jupyter notebook tutorial for Chroma. ## Test Plan All existing tests pass after this change. In addition, the `test_chroma_update_document` test case now correctly checks the functionality of `update_document`, ensuring that the function works as expected and updates the content of documents correctly. ## Reviewers @dev2049 This fix will ensure that users are able to use the `update_document` function as expected, without encountering the previous `AttributeError`. This will enhance the usability and reliability of the Chroma class for all users. Thank you for considering this pull request. I look forward to your feedback and suggestions.	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.

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

Jon Saginaw	ea64b1716d	Enhancement: option to Get All Tokens with a single Blockchain Document Loader call (#3797 ) The Blockchain Document Loader's default behavior is to return 100 tokens at a time which is the Alchemy API limit. The Document Loader exposes a startToken that can be used for pagination against the API. This enhancement includes an optional get_all_tokens param (default: False) which will: - Iterate over the Alchemy API until it receives all the tokens, and return the tokens in a single call to the loader. - Manage all/most tokenId formats (this can be int, hex16 with zero or all the leading zeros). There aren't constraints as to how smart contracts can represent this value, but these three are most common. Note that a contract with 10,000 tokens will issue 100 calls to the Alchemy API, and could take about a minute, which is why this param will default to False. But I've been using the doc loader with these utilities on the side, so figured it might make sense to build them in for others to use.	1 year ago

Luke Harris	b4de839ed8	Several confluence loader improvements (#3300 ) This PR addresses several improvements: - Previously it was not possible to load spaces of more than 100 pages. The `limit` was being used both as an overall page limit and as a per request pagination limit. This, in combination with the fact that atlassian seem to use a server-side hard limit of 100 when page content is expanded, meant it wasn't possible to download >100 pages. Now `limit` is used only as a per-request pagination limit and `max_pages` is introduced as the way to limit the total number of pages returned by the paginator. - Document metadata now includes `source` (the source url), making it compatible with `RetrievalQAWithSourcesChain`. - It is now possible to include inline and footer comments. - It is now possible to pass `verify_ssl=False` and other parameters to the confluence object for use cases that require it.	1 year ago

vowelparrot	709f26b69e	Added bilibili loader (#2673 ) (#2724 ) I've added a bilibili loader, bilibili is a very active video site in China and I think we need this loader. Example: ```python from langchain.document_loaders.bilibili import BiliBiliLoader loader = BiliBiliLoader( ["https://www.bilibili.com/video/BV1xt411o7Xu/", "https://www.bilibili.com/video/av330407025/"] ) docs = loader.load() ``` Co-authored-by: 了空 <568250549@qq.com>	1 year ago

Chetanya Rastogi	50c511d75f	Add new loader to load pdf as html content (#2607 ) Adds a new pdf loader using the existing dependency on PDFMiner. The new loader can be helpful for chunking texts semantically into sections as the output html content can be parsed via `BeautifulSoup` to get more structured and rich information about font size, page numbers, pdf headers/footers, etc. which may not be available otherwise with other pdf loaders	1 year ago
sergerdn	6dc86ad48f	feat: add pytest-vcr for recording HTTP interactions in integration tests (#2445 ) Using `pytest-vcr` in integration tests has several benefits. Firstly, it removes the need to mock external services, as VCR records and replays HTTP interactions on the fly. Secondly, it simplifies the integration test setup by eliminating the need to set up and tear down external services in some cases. Finally, it allows for more reliable and deterministic integration tests by ensuring that HTTP interactions are always replayed with the same response. Overall, `pytest-vcr` is a valuable tool for simplifying integration test setup and improving their reliability This commit adds the `pytest-vcr` package as a dependency for integration tests in the `pyproject.toml` file. It also introduces two new fixtures in `tests/integration_tests/conftest.py` files for managing cassette directories and VCR configurations. In addition, the `tests/integration_tests/vectorstores/test_elasticsearch.py` file has been updated to use the `@pytest.mark.vcr` decorator for recording and replaying HTTP interactions. Finally, this commit removes the `documents` fixture from the `test_elasticsearch.py` file and replaces it with a new fixture defined in `tests/integration_tests/vectorstores/conftest.py` that yields a list of documents to use in any other tests. This also includes my second attempt to fix issue : https://github.com/hwchase17/langchain/issues/2386 Maybe related https://github.com/hwchase17/langchain/issues/2484	1 year ago
