Leonid Ganeline	e787532479	langchain: `globals` fix (#21281 ) Issue: functions from `globals`, like the `get_debug` are placed in the init.py file. As a result, they don't listed in the API Reference docs. [See this](https://langchain-9jq1kef7i-langchain.vercel.app/v0.2/docs/how_to/debugging/#set_debugtrue) and [broken this](https://api.python.langchain.com/en/latest/globals/langchain.globals.set_debug.html). Change: moved code from init.py into the `globals.py` file and removed `globals` directory. Similar to: #21266 BTW `globals` in core implemented exactly inside a file not inside a folder.	2 months ago

Alexander Golodkov	2a70a07aad	community[minor]: added new document loaders based on dedoc library (#24303 ) ### Description This pull request added new document loaders to load documents of various formats using [Dedoc](https://github.com/ispras/dedoc): - `DedocFileLoader` (determine file types automatically and parse) - `DedocPDFLoader` (for `PDF` and images parsing) - `DedocAPIFileLoader` (determine file types automatically and parse using Dedoc API without library installation) [Dedoc](https://dedoc.readthedocs.io) is an open-source library/service that extracts texts, tables, attached files and document structure (e.g., titles, list items, etc.) from files of various formats. The library is actively developed and maintained by a group of developers. `Dedoc` supports `DOCX`, `XLSX`, `PPTX`, `EML`, `HTML`, `PDF`, images and more. Full list of supported formats can be found [here](https://dedoc.readthedocs.io/en/latest/#id1). For `PDF` documents, `Dedoc` allows to determine textual layer correctness and split the document into paragraphs. ### Issue This pull request extends variety of document loaders supported by `langchain_community` allowing users to choose the most suitable option for raw documents parsing. ### Dependencies The PR added a new (optional) dependency `dedoc>=2.2.5` ([library documentation](https://dedoc.readthedocs.io)) to the `extended_testing_deps.txt` ### Twitter handle None ### Add tests and docs 1. Test for the integration: `libs/community/tests/integration_tests/document_loaders/test_dedoc.py` 2. Example notebook: `docs/docs/integrations/document_loaders/dedoc.ipynb` 3.

MarkYQJ	df357f82ca	ignore the first turn to apply "history" mechanism (#14118 ) This will generate a meaningless string "system: " for generating condense question; this increases the probability to make an improper condense question and misunderstand user's question. Below is a case - Original Question: Can you explain the arguments of Meilisearch? - Condense Question - What are the benefits of using Meilisearch? (by CodeLlama) - What are the reasons for using Meilisearch? (by GPT-4) The condense questions (not matter from CodeLlam or GPT-4) are different from the original one. By checking the content of each dialogue turn, generating history string only when the dialog content is not empty. Since there is nothing before first turn, the "history" mechanism will be ignored at the very first turn. Doing so, the condense question will be "What are the arguments for using Meilisearch?". <!-- Thank you for contributing to LangChain!

ccurme	0f7569ddbc	core[patch]: enable RunnableWithMessageHistory without config (#23775 ) Feedback that `RunnableWithMessageHistory` is unwieldy compared to ConversationChain and similar legacy abstractions is common. Legacy chains using memory typically had no explicit notion of threads or separate sessions. To use `RunnableWithMessageHistory`, users are forced to introduce this concept into their code. This possibly felt like unnecessary boilerplate. Here we enable `RunnableWithMessageHistory` to run without a config if the `get_session_history` callable has no arguments. This enables minimal implementations like the following: ```python from langchain_core.chat_history import InMemoryChatMessageHistory from langchain_core.runnables.history import RunnableWithMessageHistory from langchain_openai import ChatOpenAI llm = ChatOpenAI(model="gpt-3.5-turbo-0125") memory = InMemoryChatMessageHistory() chain = RunnableWithMessageHistory(llm, lambda: memory) chain.invoke("Hi I'm Bob") # Hello Bob! chain.invoke("What is my name?") # Your name is Bob. ```	2 months ago

Sheng Han Lim	0c6a3fdd6b	langchain: Update ContextualCompressionRetriever base_retriever type to RetrieverLike (#24192 ) Description: When initializing retrievers with `configurable_fields` as base retriever, `ContextualCompressionRetriever` validation fails with the following error: ``` ValidationError: 1 validation error for ContextualCompressionRetriever base_retriever Can't instantiate abstract class BaseRetriever with abstract method _get_relevant_documents (type=type_error) ``` Example code: ```python esearch_retriever = VertexAISearchRetriever( project_id=GCP_PROJECT_ID, location_id="global", data_store_id=SEARCH_ENGINE_ID, ).configurable_fields( filter=ConfigurableField(id="vertex_search_filter", name="Vertex Search Filter") ) # rerank documents with Vertex AI Rank API reranker = VertexAIRank( project_id=GCP_PROJECT_ID, location_id=GCP_REGION, ranking_config="default_ranking_config", ) retriever_with_reranker = ContextualCompressionRetriever( base_compressor=reranker, base_retriever=esearch_retriever ) ``` It seems like the issue stems from ContextualCompressionRetriever insisting that base retrievers must be strictly `BaseRetriever` inherited, and doesn't take into account cases where retrievers need to be chained and can have configurable fields defined. `0a1e475a30/libs/langchain/langchain/retrievers/contextual_compression.py (L15-L22)` This PR proposes that the base_retriever type be set to `RetrieverLike`, similar to how `EnsembleRetriever` validates its list of retrievers: `0a1e475a30/libs/langchain/langchain/retrievers/ensemble.py (L58-L75)`	2 months ago
