Jeff Vestal	d1f65d8dc1	Es knn index search 5346 (#5569 ) # Create elastic_vector_search.ElasticKnnSearch class This extends `langchain/vectorstores/elastic_vector_search.py` by adding a new class `ElasticKnnSearch` Features: - Allow creating an index with the `dense_vector` mapping compataible with kNN search - Store embeddings in index for use with kNN search (correct mapping creates HNSW data structure) - Perform approximate kNN search - Perform hybrid BM25 (`query{}`) + kNN (`knn{}`) search - perform knn search by either providing a `query_vector` or passing a hosted `model_id` to use query_vector_builder to automatically generate a query_vector at search time Connection options - Using `cloud_id` from Elastic Cloud - Passing elasticsearch client object search options - query - k - query_vector - model_id - size - source - knn_boost (hybrid search) - query_boost (hybrid search) - fields This also adds examples to `docs/modules/indexes/vectorstores/examples/elasticsearch.ipynb` Fixes # [5346](https://github.com/hwchase17/langchain/issues/5346) cc: @dev2049 --> --------- Co-authored-by: Dev 2049 <dev.dev2049@gmail.com>	1 year ago

Ehsan M. Kermani	4a246e2fd6	Allow clearing cache and fix gptcache (#3493 ) This PR * Adds `clear` method for `BaseCache` and implements it for various caches * Adds the default `init_func=None` and fixes gptcache integtest * Since right now integtest is not running in CI, I've verified the changes by running `docs/modules/models/llms/examples/llm_caching.ipynb` (until proper e2e integtest is done in CI)	1 year ago
Quentin Pleplé	126d7f11dd	Fix notebook example (#3142 ) The following calls were throwing an exception: `575b717d10/docs/use_cases/evaluation/agent_vectordb_sota_pg.ipynb`?short_path=4b3386c#L192 `575b717d10/docs/use_cases/evaluation/agent_vectordb_sota_pg.ipynb`?short_path=4b3386c#L239 Exception: ``` --------------------------------------------------------------------------- ValidationError Traceback (most recent call last) Cell In[14], line 1 ----> 1 chain_sota = RetrievalQA.from_chain_type(llm=OpenAI(temperature=0), chain_type="stuff", retriever=vectorstore_sota, input_key="question") File ~/github/langchain/venv/lib/python3.9/site-packages/langchain/chains/retrieval_qa/base.py:89, in BaseRetrievalQA.from_chain_type(cls, llm, chain_type, chain_type_kwargs, kwargs) 85 _chain_type_kwargs = chain_type_kwargs or {} 86 combine_documents_chain = load_qa_chain( 87 llm, chain_type=chain_type, _chain_type_kwargs 88 ) ---> 89 return cls(combine_documents_chain=combine_documents_chain, *kwargs) File ~/github/langchain/venv/lib/python3.9/site-packages/pydantic/main.py:341, in pydantic.main.BaseModel.__init__() ValidationError: 1 validation error for RetrievalQA retriever instance of BaseRetriever expected (type=type_error.arbitrary_type; expected_arbitrary_type=BaseRetriever) ``` The vectorstores had to be converted to retrievers: `vectorstore_sota.as_retriever()` and `vectorstore_pg.as_retriever()`. The PR also: - adds the file `paul_graham_essay.txt` referenced by this notebook - adds to gitignore .pkl and *.bin files that are generated by this notebook Interestingly enough, the performance of the prediction greatly increased (new version of langchain or ne version of OpenAI models since the last run of the notebook): from 19/33 correct to 28/33 correct!	1 year ago
sergerdn	b410dc76aa	fix: elasticsearch (#2402 ) - Create a new docker-compose file to start an Elasticsearch instance for integration tests. - Add new tests to `test_elasticsearch.py` to verify Elasticsearch functionality. - Include an optional group `test_integration` in the `pyproject.toml` file. This group should contain dependencies for integration tests and can be installed using the command `poetry install --with test_integration`. Any new dependencies should be added by running `poetry add some_new_deps --group "test_integration" ` Note: New tests running in live mode, which involve end-to-end testing of the OpenAI API. In the future, adding `pytest-vcr` to record and replay all API requests would be a nice feature for testing process.More info: https://pytest-vcr.readthedocs.io/en/latest/ Fixes https://github.com/hwchase17/langchain/issues/2386	1 year ago
