### Issue you'd like to raise. The llm loader `load_llm_from_config` defined [here](https://github.com/langchain-ai/langchain/blob/master/libs/langchain/langchain/llms/loading.py#L12) only returns `BaseLLM`s. There is no equivalent chat_model loader in langchain to load Chat Model LLMs from a config that I'm aware of. What do you think of either extending the `load_llm_from_config` such that it returns both `BaseLLM` and `BaseChatModel` ``` load_llm_from_config(config: dict) -> Union[BaseLLM, BaseChatModel] ``` or create a chat_model loader in `langchain.chat_models.loading.py` ``` load_chat_llm_from_config(config: dict) -> BaseChatModel ``` ### Suggestion: _No response_

This commit addresses the issue where JSON strings with trailing commas would cause parsing to fail. We have added a preprocessing step to correct these commas before attempting to parse the JSON string using the `json.loads()` function. Changes: - Added a `correct_trailing_commas` function that removes trailing commas from a given JSON string. - Used this function to preprocess the JSON string inside the `parse` method of `PydanticOutputParser`. Reason: Some JSON producing systems or manual entries might inadvertently add trailing commas, which are not valid in standard JSON. This change aims to make our parser more robust and forgiving of such common mistakes, thereby reducing potential disruptions or failures due to invalid JSON formats. <!-- Thank you for contributing to LangChain!

### Issue you'd like to raise. Hello, I'm trying to change dynamically a prompt, based on the value of the context in a ConversationalRetrievalChain ``` prompt_template = """You are an AI assistant. Use the following pieces of context to answer the question, in a precise way, at the end. Context: {context if context else "some default: I don't have information about it"} Question: {question} Helpful Answer :""" QA_PROMPT = PromptTemplate( template=prompt_template, input_variables=["context", "question"] ) llm = AzureChatOpenAI( temperature=0, deployment_name="gpt-35-turbo", ) memory = ConversationBufferWindowMemory( k=1, output_key='answer', memory_key='chat_history', return_messages=True) retriever = vector.as_retriever(search_type="similarity_score_threshold", search_kwargs={"score_threshold": .70}) qa_chain = ConversationalRetrievalChain.from_llm(llm=llm, memory=memory, retriever=retriever, condense_question_prompt=CONDENSE_QUESTION_PROMPT, combine_docs_chain_kwargs={'prompt': QA_PROMPT}, return_source_documents=True, verbose=True) ``` The idea is when the retriever gets 0 documents, to have something in the context that push the model to say I don't know and don't make up and answer. I already try by adding in the prompt "if you don't know the answer don't make it up" and didn't work. Any idea how to add a condition in the template or control the LLM based on the output of the retriever? ### Suggestion: _No response_

### Issue you'd like to raise. I use Qdrant through langchain to store vectors. But I can't find any example in docs where the dataset is searched based on a previously created collection. How to load the data? I found that Pinecone has "from_existing_index" function, which probably does the thing. But Qdrant doesn't have such a function. I created my own solution using qdrant_client, but I would like to use Langchain to simplify the script. How to do it? ### Suggestion: _No response_

### Feature request I am using Weaviate with ConversationalRetrievalChain I am using `similarity_score_threshold` search type. It will call `similarity_search_with_score` in `vectorstore/weaviate.py` Currently it's written like this ` if not self._by_text: vector = {"vector": embedded_query} result = ( query_obj.with_near_vector(vector) .with_limit(k) .with_additional("vector") .do() ) else: result = ( query_obj.with_near_text(content) .with_limit(k) .with_additional("vector") .do() ) ` The `with_additional` function can accept a list of `AdditionalProperties` So there's no point of hardcoding to be just the vector, and let the user add the additional arguments required. I've tested this just by changing ` .with_additional("vector")` to ` .with_additional(["vector", "certainty"] )` and it works just fine ### Motivation I am using the Conversational Chain just because it's easier to manage than creating one. But it's limitations are apparent. I want to retrieve the scores it get which is currently not possible ### Your contribution I don't know how to pass in the `_additional` arguments from the vectorstore.as_retriever() but just hard coding the args i want the tests worked fine.

### Issue with current documentation: The first code example following the Pydantic section, right after "Lets define a class with attributes annotated with types." results for me in the following pydantic errors using gpt-4: RuntimeError: no validator found for <class '__main__.Properties'>, see `arbitrary_types_allowed` in Config The following versions of langchain and pydantic were used: langchain==0.0.309 pydantic==2.4.2 pydantic_core==2.10.1 ### Idea or request for content: It would be nice to have the code updated so that it works out of the box. Perhaps a reference to the extraction functions in the 'openai functions' section would be nice.

### System Info Langchain version : 0.0.292 Python version: 3.9.13 Platform: Apple M1, Sonoma 14.0 ### Who can help? @eyurtsev @hwc ### Information - [x] The official example notebooks/scripts - [X] My own modified scripts ### Related Components - [ ] LLMs/Chat Models - [ ] Embedding Models - [ ] Prompts / Prompt Templates / Prompt Selectors - [ ] Output Parsers - [X] Document Loaders - [ ] Vector Stores / Retrievers - [ ] Memory - [ ] Agents / Agent Executors - [ ] Tools / Toolkits - [ ] Chains - [ ] Callbacks/Tracing - [ ] Async ### Reproduction Steps to reproduce: 1. Have a google drive folder with multiple documents with formats like`.mp4`, `.md`, `google docs`, `google sheets` etc. 2. Try using `from langchain.document_loaders import GoogleDriveLoader`, it doesn't work as it only supports google docs, google sheets and pdf files. ``` folder_id = "0ABqitCqK0S_MUk9PVA" # have your own folder id, this is an example loader = GoogleDriveLoader( gdrive_api_file=GOOGLE_ACCOUNT_FILE, folder_id= folder_id, recursive=True, # num_results=2, # Maximum number of file to load ) ``` 3. Try using `from langchain.document_loaders import UnstructuredFileIOLoader` to load ``` folder_id = "0ABqitCqK0S_MUk9PVA" # have your own folder id, this is an example loader = GoogleDriveLoader( service_account_key=GOOGLE_ACCOUNT_FILE, folder_id=folder_id, file_loader_cls=UnstructuredFileIOLoader, file_loader_kwargs={"mode": "elements"}, recursive=True ) ``` 4. It throws the following error because `.mp4` files are not supported `The MIME type is 'video/mp4'. This file type is not currently supported in unstructured. --------------------------------------------------------------------------- ValueError Traceback (most recent call last) Input In [34], in <cell line: 3>() 1 start_time = time.time() ----> 3 docs = loader.load() 5 print("Total docs loaded", len(docs)) 7 end_time = time.time() - start_time File /opt/homebrew/Caskroom/miniforge/base/envs/py39/lib/python3.9/site-packages/langchain/document_loaders/googledrive.py:351, in GoogleDriveLoader.load(self) 349 """Load documents.""" 350 if self.folder_id: --> 351 return self._load_documents_from_folder( 352 self.folder_id, file_types=self.file_types 353 ) 354 elif self.document_ids: 355 return self._load_documents_from_ids() File /opt/homebrew/Caskroom/miniforge/base/envs/py39/lib/python3.9/site-packages/langchain/document_loaders/googledrive.py:257, in GoogleDriveLoader._load_documents_from_folder(self, folder_id, file_types) 252 returns.extend(self._load_sheet_from_id(file["id"])) # type: ignore 253 elif ( 254 file["mimeType"] == "application/pdf" 255 or self.file_loader_cls is not None 256 ): --> 257 returns.extend(self._load_file_from_id(file["id"])) # type: ignore 258 else: 259 pass File /opt/homebrew/Caskroom/miniforge/base/envs/py39/lib/python3.9/site-packages/langchain/document_loaders/googledrive.py:316, in GoogleDriveLoader._load_file_from_id(self, id) 314 fh.seek(0) 315 loader = self.file_loader_cls(file=fh, **self.file_loader_kwargs) --> 316 docs = loader.load() 317 for doc in docs: 318 doc.metadata["source"] = f"https://drive.google.com/file/d/{id}/view" File /opt/homebrew/Caskroom/miniforge/base/envs/py39/lib/python3.9/site-packages/langchain/document_loaders/unstructured.py:86, in UnstructuredBaseLoader.load(self) 84 def load(self) -> List[Document]: 85 """Load file.""" ---> 86 elements = self._get_elements() 87 self._post_process_elements(elements) 88 if self.mode == "elements": File /opt/homebrew/Caskroom/miniforge/base/envs/py39/lib/python3.9/site-packages/langchain/document_loaders/unstructured.py:319, in UnstructuredFileIOLoader._get_elements(self) 316 def _get_elements(self) -> List: 317 from unstructured.partition.auto import partition --> 319 return partition(file=self.file, **self.unstructured_kwargs) File /opt/homebrew/Caskroom/miniforge/base/envs/py39/lib/python3.9/site-packages/unstructured/partition/auto.py:183, in partition(filename, content_type, file, file_filename, url, include_page_breaks, strategy, encoding, paragraph_grouper, headers, ssl_verify, ocr_languages, pdf_infer_table_structure) 181 else: 182 msg = "Invalid file" if not filename else f"Invalid file {filename}" --> 183 raise ValueError(f"{msg}. The {filetype} file type is not supported in partition.") 185 for element in elements: 186 element.metadata.url = url ValueError: Invalid file. The FileType.UNK file type is not supported in partition. ` ### Expected behavior I would expect this error to be handled by the loader, simply ignore the unsupported files and load the rest. Can throw some warning to notify but not break the code.

- **Description:** Quote tool names in prompt templates - **Issue:** https://github.com/langchain-ai/langchain/issues/1657 https://github.com/langchain-ai/langchain/issues/1477 https://github.com/langchain-ai/langchain/issues/1358 - **Tag maintainer:** @hwchase17 The original prompt template is ambiguous because it does not tell whether the tool names should be quoted or not. This PR makes it clear that the tool names should be quoted. It fixes #1358 for Nous-Hermes-Llama2-13b according to my tests.

- **Description:** This commit corrects a minor typo in the documentation. It changes "frum" to "from" in the sentence: "The results from search are passed back to the LLM for synthesis into an answer" in the file `docs/extras/use_cases/more/agents/agents.ipynb`. This typo fix enhances the clarity and accuracy of the documentation. - **Tag maintainer:** @baskaryan

### System Info LangChain: 0.0.250 Python: 3.11.4 OS: Pop 22.04 ### Who can help? @agola11 @eyurtsev ### Information - [ ] The official example notebooks/scripts - [X] My own modified scripts ### Related Components - [ ] LLMs/Chat Models - [ ] Embedding Models - [ ] Prompts / Prompt Templates / Prompt Selectors - [ ] Output Parsers - [X] Document Loaders - [ ] Vector Stores / Retrievers - [ ] Memory - [ ] Agents / Agent Executors - [ ] Tools / Toolkits - [ ] Chains - [ ] Callbacks/Tracing - [ ] Async ### Reproduction **Input** ```py from pathlib import Path from langchain.document_loaders.blob_loaders.schema import Blob from langchain.document_loaders.parsers.audio import OpenAIWhisperParser OPENAI_API_KEY = "<MY-KEY>" audio_file = Path("~/Downloads/audio.mp3").expanduser() audio_total_seconds = AudioSegment.from_file(audio_file).duration_seconds print("Audio length (seconds):", audio_total_seconds) blob = Blob.from_path(audio_file, mime_type="audio/mp3") parser = OpenAIWhisperParser(api_key=OPENAI_API_KEY) parser.parse(blob) ``` **Output** ``` Audio length (seconds): 1200.064 Transcribing part 1! Transcribing part 2! Attempt 1 failed. Exception: Audio file is too short. Minimum audio length is 0.1 seconds. Attempt 2 failed. Exception: Invalid file format. Supported formats: ['flac', 'm4a', 'mp3', 'mp4', 'mpeg', 'mpga', 'oga', 'ogg', 'wav', 'webm'] Attempt 3 failed. Exception: Invalid file format. Supported formats: ['flac', 'm4a', 'mp3', 'mp4', 'mpeg', 'mpga', 'oga', 'ogg', 'wav', 'webm'] Failed to transcribe after 3 attempts. ``` ### Expected behavior Due to its internal rule of processing audio in [20-minute chunks](https://github.com/langchain-ai/langchain/blob/master/libs/langchain/langchain/document_loaders/parsers/audio.py#L47), `OpenAIWhisperParser` is prone to crashing when transcribing audio with durations that are dangerously close to this limit. Given that OpenAI already has a very low audio length threshold of 0.1 seconds, a simple bypass could effectively resolve this issue. ```python # https://github.com/langchain-ai/langchain/blob/master/libs/langchain/langchain/document_loaders/parsers/audio.py#L47 chunk_duration = 20 chunk_duration_ms = chunk_duration * 60 * 1000 chunk_length_threshold = 0.1 # Split the audio into chunk_duration_ms chunks for split_number, i in enumerate(range(0, len(audio), chunk_duration_ms)): # Audio chunk chunk = audio[i : i + chunk_duration_ms] if chunk.duration_seconds < chunk_length_threshold: continue ```

Hello there, I have deployed an OpenLLM on a managed service that is protected by the use of an auth Bearer token: ```bash curl -X 'POST' \ 'https://themodel.url/v1/generate' \ -H "Authorization: Bearer Sh6Kh4[ . . . super long bearer token ]W18UiWuzsz+0r+U" -H 'accept: application/json' \ -H 'Content-Type: application/json' \ -d '{ "prompt": "What is the difference between a pigeon", "llm_config": { "use[ . . . and so on] } }' ``` Curl works like a charm. In LangChain, I try to create my new llm as such: ```python llm = OpenLLM(server_url="https://themodel.url/v1/generate", temperature=0.2) ``` But I don't know how to include this Bearer token, I even suspect it is impossible... **Bot seems to confirm this is impossible as of 5 Oct 2023, as seen in https://github.com/langchain-ai/langchain/discussions/11437** ; this issue would then be a feature request. Thanks! Cheers, Colin _Originally posted by @ColinLeverger in https://github.com/langchain-ai/langchain/discussions/11437_

- **Description:** Fix the `PyMuPDFLoader` to accept `loader_kwargs` from the document loader's `loader_kwargs` option. This provides more flexibility in formatting the output from documents. - **Issue:** The `loader_kwargs` is not passed into the `load` method from the document loader, which limits configuration options. - **Dependencies:** None

### System Info python: 3.11 langchain: 0.0.306 ### Who can help? Although PGVector implementation utilizes SQLAlchemy that supports connection pooling features, it gets one connection from the pool, saves it as a class attribute and reuses in all requests. ```python class PGVector(VectorStore): # ... def __init__( self, # ... ) -> None: # ... self.__post_init__() def __post_init__( self, ) -> None: self._conn = self.connect() # ... def create_vector_extension(self) -> None: try: with Session(self._conn) as session: # ... except Exception as e: self.logger.exception(e) def create_tables_if_not_exists(self) -> None: with self._conn.begin(): Base.metadata.create_all(self._conn) @contextlib.contextmanager def _make_session(self) -> Generator[Session, None, None]: yield Session(self._conn) # ... ``` This means that: - Since the same connection is user for handle all requests, they will not be executed in parallel but rather enqueued. In a scenario with a large number of requests, this may not scale well. - Great pool features like connection recycle and test for liveness can not be used. @hwchase17 @eyurtsev ### Information - [ ] The official example notebooks/scripts - [X] My own modified scripts ### Related Components - [ ] LLMs/Chat Models - [ ] Embedding Models - [ ] Prompts / Prompt Templates / Prompt Selectors - [ ] Output Parsers - [ ] Document Loaders - [X] Vector Stores / Retrievers - [ ] Memory - [ ] Agents / Agent Executors - [ ] Tools / Toolkits - [ ] Chains - [ ] Callbacks/Tracing - [ ] Async ### Reproduction 1. Configure Postgres to kill idle sessions after 10 seconds (I'm using the `ankane/pgvector` docker image): ```sql ALTER SYSTEM SET idle_session_timeout TO '10000'; ALTER SYSTEM SET idle_in_transaction_session_timeout TO '10000'; ``` 2. Restart the database 3. Confirm the new settings are active ```sql SHOW ALL; ``` 4. Create a sample program that instantiate a `PGVector` class and search by similarity every 30 seconds, sleeping between each iteration ```python if __name__ == '__main__': # Logging level logging.basicConfig(level=logging.DEBUG) load_dotenv() # PG Vector driver = os.environ["PGVECTOR_DRIVER"] host = os.environ["PGVECTOR_HOST"] port = os.environ["PGVECTOR_PORT"] database = os.environ["PGVECTOR_DATABASE"] user = os.environ["PGVECTOR_USER"] password = os.environ["PGVECTOR_PASSWORD"] collection_name = "state_of_the_union_test" connection_string = f'postgresql+{driver}://{user}:{password}@{host}:{port}/{database}' embeddings = OpenAIEmbeddings() loader = TextLoader("./state_of_the_union.txt") documents = loader.load() text_splitter = CharacterTextSplitter(chunk_size=1000, chunk_overlap=0) chunks = text_splitter.split_documents(documents) db = PGVector.from_documents( embedding=embeddings, documents=chunks, collection_name=collection_name, connection_string=connection_string, ) for i in range(100): try: print('--> *** Searching by similarity ***') result = db.similarity_search_with_score("foo") print('--> *** Documents retrieved successfully ***') # for doc, score in result: # print(f'{score}:{doc.page_content}') except Exception as e: print('--> *** Fail ***') print(str(e)) print('--> *** Sleeping ***') time.sleep(30) print('\n\n') ``` 5.

- **Description:** Fix the `PyMuPDFLoader` to accept `loader_kwargs` from the document loader's `loader_kwargs` option. This provides more flexibility in formatting the output documents. - **Issue:** The `loader_kwargs` is not passed into the `load` method from the document loader, which limits configuration options. - **Dependencies:** None

**Description:** Previously when setting up a structured tool with multiple parameters e.g. `arg1, arg2` we got a schema validation error by pydantic. The reason for this was simple: Although the required parameters for the tool were correctly identified, they were propagated as string e.g. `'{"arg1": "foo", "arg2": "bar"}'` This PR fixes this issue by using the `parse_raw` method if the args are of type string **Issue:** Didn't find a related issue. **Dependencies:** None **Tag maintainer:** None **Twitter handle:** None /CC @Depaccu

### System Info I am using Python 3.11.5 and I run into this issue with `ModuleNotFoundError: No module named 'langchain.document_loaders'` after running `pip install 'langchain[all]'`, which appears to be installing langchain-0.0.39 If I then run `pip uninstall langchain`, followed by `pip install langchain`, it proceeds to install langchain-0.0.308 and suddenly my document loaders work again. - Why does langchain 0.0.39 have document_loaders broken? - Why does langchain[all] install a different version of langchain? ### Reproduction 1. Install python 3.11.5 (using pyenv on OSX) 2. Run `pip install `langchain[all]'` 3. Observe langchain version that is installed 4. Run `ipython` and execute `from langchain.document_loaders import WebBaseLoader` to receive the module error. 5. Run `pip uninstall langchain` 6. Run `pip install langchain` 7. Note how an older version of langchain is installed 8. Run `ipython` and execute `from langchain.document_loaders import WebBaseLoader` to see how it's working. ### Expected behavior `pip install langchain` should install the same underlying version of langchain as the version of langchain that includes all of the various modules.

### Issue with current documentation: In [QA using a Retriever docs](https://python.langchain.com/docs/use_cases/question_answering/how_to/vector_db_qa) you can observe that after each LLM reply we observe additional empty space. What is the purpose of having this space or is it just a bug in Prompt? Copied from the docs provided above ```python3 query = "What did the president say about Ketanji Brown Jackson" qa.run(query) ``` Provides response: `" The president said that she is one of the nation's top legal minds ..."` ### Idea or request for content: _No response_

### Issue you'd like to raise. I am trying to access documents from SharePoint using Langchain's [SharePointLoader](https://api.python.langchain.com/en/latest/document_loaders/langchain.document_loaders.sharepoint.SharePointLoader.html). I changed the redirect URI to a local host on this [documentation](https://python.langchain.com/docs/integrations/document_loaders/microsoft_sharepoint). How can I pass the new redirect URI as a parameter to the [SharePointLoader](https://api.python.langchain.com/en/latest/document_loaders/langchain.document_loaders.sharepoint.SharePointLoader.html) function. ### Suggestion: _No response_

I have restructured the code to ensure uniform handling of ImportError. In place of previously used ValueError, I've adopted the standard practice of raising ImportError with explanatory messages. This modification enhances code readability and clarifies that any problems stem from module importation. @baskaryan

I was hoping this would pick up numpy 1.26, which is required to support the new Python 3.12 release, but it didn't. It seems that some transitive dependency requirement on numpy is preventing that, and the highest we can currently go is 1.24.x. But to find this out required a 15min `poetry lock`, so I figured we might as well upgrade the dependencies we can and hopefully make the next dependency upgrade a bit smaller.

This PR adds [Bigframes (BigQuery DataFrames)](https://cloud.google.com/python/docs/reference/bigframes/latest) integration to Langchain. BigQuery DataFrames provides a Pythonic DataFrame and machine learning (ML) API powered by the BigQuery engine. BigFrames supports manipulating data in the DataFrame to build LLM prompts, and sending DataFrame prompts to the LLM model using [text-bison model of the PaLM API](https://cloud.google.com/vertex-ai/docs/generative-ai/model-reference/text) <!-- Thank you for contributing to LangChain!

### Issue with current documentation: In the documentation for some examples like [Weaviate](https://api.python.langchain.com/en/latest/vectorstores/langchain.vectorstores.weaviate.Weaviate.html#langchain.vectorstores.weaviate.Weaviate.delete) and [ElasticsearchVectorStore](https://api.python.langchain.com/en/latest/vectorstores/langchain.vectorstores.elasticsearch.ElasticsearchStore.html#langchain.vectorstores.elasticsearch.ElasticsearchStore.delete), the delete method is described as having the ids parameter as optional. `delete(ids: Optional[List[str]] = None, **kwargs: Any) → None` However, the ids parameter is mandatory for those vectorstores, and if it is not provided, a ValueError will be raised with the message "No ids provided to delete." Here is the revised [documentation](https://github.com/langchain-ai/langchain/blob/b9fad28f5e093415d76aeb71b5e555eb87fd2ec2/libs/langchain/langchain/vectorstores/elastic_vector_search.py#L336C5-L348C61) to clarify this: ` def delete(self, ids: Optional[List[str]] = None, **kwargs: Any) -> None: """Delete by vector IDs. Args: ids: List of ids to delete. """ if ids is None: raise ValueError("No ids provided to delete.") # TODO: Check if this can be done in bulk for id in ids: self.client.delete(index=self.index_name, id=id) ` ### Idea or request for content: Please clarify in the documentation Is it also possible to get bulk delete functionality for some vectorstore (ex. ElasticsearchVectorStore/ Weviate)?

### Feature request I would like to implement a `ListOutputParser` that could transform Markdown list into a string list ### Motivation It seems that most of the lists generated by LLMs are Markdown lists, so I think this will be useful. It might also make it easier to handle cases where the generated list doesn't work with the existing `ListOutputParser` (Numered and CommaSeparated). ### Your contribution Here is the PR: https://github.com/langchain-ai/langchain/pull/11411

I've looked into the documentation but I can't tell if I'm missing something or not. How do I get this working?

The person class here: https://python.langchain.com/docs/use_cases/extraction#pydantic-1 has attributes `dog_breed` and `dog_name` that use `Optional` from typing, but it hasn't been imported. Fixed the import here <!-- Thank you for contributing to LangChain! Replace this entire comment with: - **Description:** Fix python imports in example, - **Issue:** the issue # it fixes (if applicable), - **Dependencies:** any dependencies required for this change, - **Tag maintainer:** for a quicker response, tag the relevant maintainer (see below), - **Twitter handle:** we announce bigger features on Twitter. If your PR gets announced, and you'd like a mention, we'll gladly shout you out! Please make sure your PR is passing linting and testing before submitting. Run `make format`, `make lint` and `make test` to check this locally. See contribution guidelines for more information on how to write/run tests, lint, etc: https://github.com/langchain-ai/langchain/blob/master/.github/CONTRIBUTING.md If you're adding a new integration, please include: 1. a test for the integration, preferably unit tests that do not rely on network access, 2. an example notebook showing its use. It lives in `docs/extras` directory. If no one reviews your PR within a few days, please @-mention one of @baskaryan, @eyurtsev, @hwchase17. -->

It lives in `docs/extras` directory. If no one reviews your PR within a few days, please @-mention one of @baskaryan, @eyurtsev, @hwchase17. --> ## Description Currently SQLAlchemy >=1.4.0 is a hard requirement. We are unable to run `from langchain.vectorstores import FAISS` with SQLAlchemy <1.4.0 due to top-level imports, even if we aren't even using parts of the library that use SQLAlchemy. See Testing section for repro. Let's make it so that langchain is still compatible with SQLAlchemy <1.4.0, especially if we aren't using parts of langchain that require it. The main conflict is that SQLAlchemy removed `declarative_base` from `sqlalchemy.ext.declarative` in 1.4.0 and moved it to `sqlalchemy.orm`. We can fix this by try-catching the import. This is the same fix as applied in https://github.com/langchain-ai/langchain/pull/883. (I see that there seems to be some refactoring going on about isolating dependencies, e.g. https://github.com/langchain-ai/langchain/commit/c87e9fb2ce0ae617e3b2edde52421c80adef54cc, so if this issue will be eventually fixed by isolating imports in langchain.vectorstores that also works). ## Issue I can't find a matching issue. ## Dependencies No additional dependencies ## Maintainer @hwchase17 since you reviewed https://github.com/langchain-ai/langchain/pull/883 ## Testing I didn't add a test, but I manually tested this. 1. Current failure: ``` langchain==0.0.305 sqlalchemy==1.3.24 ``` ``` python python -i >>> from langchain.vectorstores import FAISS Traceback (most recent call last): File "<stdin>", line 1, in <module> File "/pay/src/zoolander/vendor3/lib/python3.8/site-packages/langchain/vectorstores/__init__.py", line 58, in <module> from langchain.vectorstores.pgembedding import PGEmbedding File "/pay/src/zoolander/vendor3/lib/python3.8/site-packages/langchain/vectorstores/pgembedding.py", line 10, in <module> from sqlalchemy.orm import Session, declarative_base, relationship ImportError: cannot import name 'declarative_base' from 'sqlalchemy.orm' (/pay/src/zoolander/vendor3/lib/python3.8/site-packages/sqlalchemy/orm/__init__.py) ``` 2. This fix: ``` langchain==<this PR> sqlalchemy==1.3.24 ``` ``` python python -i >>> from langchain.vectorstores import FAISS <succeeds> ```

### Issue you'd like to raise. I am using Lang chain version 0.0.307 and I noticed an issue with the similarity_score_threshold. I just upgraded from 0.0.208 or 288 (I forgot). This is the code I am using to retrieve the documents from pinecone: ``` docsearch = Pinecone.from_existing_index(index, embeddings, text_key="text") retriever = docsearch.as_retriever( search_type="similarity_score_threshold", search_kwargs={ 'score_threshold': 0.6 } ) retriever_docs_result = retriever.get_relevant_documents(query) ``` it used to work fine but after upgrading the langchain version it stopped returning any docs. Upon investigating the code, I've noticed that inside the `_similarity_search_with_relevance_scores` method in `vectorstore.py` , `docs_and_scores` is returning the scores as expected but then this code tries to calculate the relevance score and inverts the values: `return [(doc, relevance_score_fn(score)) for doc, score in docs_and_scores]`. I am getting search score values as 0.7 to 0.85 but then the relevancy score inverts it and makes it (1-score) which is around 0.3 to 0.15. The problem is the score_threshold works the opposite way. So if I set score_threshold to 0.6 it wants scores bigger than 0.6 which is impossible because the relevancy score makes it invert (if the relevancy score is smaller it means it is more closer to what we queried). I am using dot product and I have used the following code as well but it also didn't help: ` docsearch = Pinecone(index, embeddings, text_key="text", distance_strategy=DistanceStrategy.MAX_INNER_PRODUCT) retriever = docsearch.as_retriever( search_type="similarity_score_threshold", search_kwargs={ 'score_threshold': 0.6 } ) ` Can someone help or I am missing something here ? ### Suggestion: _No response_
