Eugene Yurtsev	f92006de3c	multiple: langchain 0.2 in master (#21191 ) 0.2rc migrations - [x] Move memory - [x] Move remaining retrievers - [x] graph_qa chains - [x] some dependency from evaluation code potentially on math utils - [x] Move openapi chain from `langchain.chains.api.openapi` to `langchain_community.chains.openapi` - [x] Migrate `langchain.chains.ernie_functions` to `langchain_community.chains.ernie_functions` - [x] migrate `langchain/chains/llm_requests.py` to `langchain_community.chains.llm_requests` - [x] Moving `langchain_community.cross_enoders.base:BaseCrossEncoder` -> `langchain_community.retrievers.document_compressors.cross_encoder:BaseCrossEncoder` (namespace not ideal, but it needs to be moved to `langchain` to avoid circular deps) - [x] unit tests langchain -- add pytest.mark.community to some unit tests that will stay in langchain - [x] unit tests community -- move unit tests that depend on community to community - [x] mv integration tests that depend on community to community - [x] mypy checks Other todo - [x] Make deprecation warnings not noisy (need to use warn deprecated and check that things are implemented properly) - [x] Update deprecation messages with timeline for code removal (likely we actually won't be removing things until 0.4 release) -- will give people more time to transition their code. - [ ] Add information to deprecation warning to show users how to migrate their code base using langchain-cli - [ ] Remove any unnecessary requirements in langchain (e.g., is SQLALchemy required?) --------- Co-authored-by: Erick Friis <erick@langchain.dev>	3 weeks ago
Silas Xu	aafaf3e193	The predict_and_parse is deprecated, instead pass an output parser directly to LLMChain. (#20130 ) The `predict_and_parse` method is deprecated, instead pass an output parser directly to LLMChain. - [x] PR title: "langchain: update chain_extract.py" ![image](https://github.com/langchain-ai/langchain/assets/40889019/e950d79f-5a0f-4086-86e9-89f627990fe5) --------- Co-authored-by: Chester Curme <chester.curme@gmail.com>	3 weeks ago

Leonid Ganeline	8c13e8a79b	langchain: `qa_chain` fix (#21279 ) Issue: `load_qa_chain` is placed in the __init__.py file. As a result, it is not listed in the API Reference docs. BTW `load_qa_chain` is heavily presented in the doc examples, but is missed in API Ref. Change: moved code from init.py into a new file. Related: #21266	3 weeks ago
Chris Papademetrious	ee6c922c91	langchain[minor]: enhance `LocalFileStore` to offer `update_atime` parameter that updates access times on read (#20951 ) Description: The `LocalFileStore` class can be used to create an on-disk `CacheBackedEmbeddings` cache. The number of files in these embeddings caches can grow to be quite large over time (hundreds of thousands) as embeddings are computed for new versions of content, but the embeddings for old/deprecated content are not removed. A least-recently-used (LRU) cache policy could be applied to the `LocalFileStore` directory to delete cache entries that have not been referenced for some time: ```bash # delete files that have not been accessed in the last 90 days find embeddings_cache_dir/ -atime 90 -print0 \| xargs -0 rm ``` However, most filesystems in enterprise environments disable access time modification on read to improve performance. As a result, the access times of these cache entry files are not updated when their values are read. To resolve this, this pull request updates the `LocalFileStore` constructor to offer an `update_atime` parameter that causes access times to be updated when a cache entry is read. For example, ```python file_store = LocalFileStore(temp_dir, update_atime=True) ``` The default is `False`, which retains the original behavior. Testing: I updated the LocalFileStore unit tests to test the access time update.	3 weeks ago

Wickes Wong	ee1adaacaa	langchain[patch]: Fix summary buffer memory with return message flag (#21115 ) ## Description Memory return could be set as `str` or `message` by `return_messages` flag as mentioned in https://python.langchain.com/docs/modules/memory/#whether-memory-is-a-string-or-a-list-of-messages, where `langchain.chains.conversation.memory.ConversationSummaryBufferMemory` did not implement that. This commit added `buffer_as_str` and `buffer_as_messages` function, and `buffer` now affected by `return_messages` flag. ## Example Test Code and Output ```python # Fix: ConversationSummaryBufferMemory with return_messages flag function # Test code from langchain.chains.conversation.memory import ConversationSummaryBufferMemory from langchain_community.llms.ollama import Ollama llm = Ollama() # Create an instance of ConversationSummaryBufferMemory with return_messages set to True memory = ConversationSummaryBufferMemory(return_messages=True, llm=llm) # Add user and AI messages to the chat memory memory.chat_memory.add_user_message("hi!") memory.chat_memory.add_ai_message("what's up?") # Print the buffer print("Buffer:") print(map(type, memory.buffer), sep="\n") print(memory.buffer, "\n") # Print the buffer as a string print("Buffer as String:") print(type(memory.buffer_as_str)) print(memory.buffer_as_str, "\n") # Print the buffer as messages print("Buffer as Messages:") print(map(type, memory.buffer_as_messages), sep="\n") print(memory.buffer_as_messages, "\n") # Print the buffer after setting return_messages to False memory.return_messages = False print("Buffer after setting return_messages to False:") print(type(memory.buffer)) print(memory.buffer, "\n") ``` ```plaintext Buffer: <class 'langchain_core.messages.human.HumanMessage'> <class 'langchain_core.messages.ai.AIMessage'> [HumanMessage(content='hi!'), AIMessage(content="what's up?")] Buffer as String: <class 'str'> Human: hi!

Buffer as Messages: <class 'langchain_core.messages.human.HumanMessage'> <class 'langchain_core.messages.ai.AIMessage'> [HumanMessage(content='hi!'), AIMessage(content="what's up?")] Buffer after setting return_messages to False: <class 'str'> Human: hi!
