I encountered this during summarization with VertexAI. I was receiving an INVALID_ARGUMENT error, as it was trying to send a list of about 17000 single characters. The [count_tokens method](https://github.com/googleapis/python-aiplatform/blob/main/vertexai/language_models/_language_models.py#L658) made available by Google takes in a list of prompts. It does not fail for small texts, but it does for longer documents because the argument list will be exceeding Googles allowed limit. Enforcing the list type makes it work successfully. This change will cast the input text to count to a list of that single text so that the input format is always correct. [Twitter](https://www.x.com/stijn_tratsaert)

This PR brings a few minor improvements to the docs, namely class/method docstrings and the demo notebook. - A note on how to control concurrency levels to tune performance in bulk inserts, both in the class docstring and the demo notebook; - Slightly increased concurrency defaults after careful experimentation (still on the conservative side even for clients running on less-than-typical network/hardware specs) - renamed the DB token variable to the standardized `ASTRA_DB_APPLICATION_TOKEN` name (used elsewhere, e.g. in the Astra DB docs) - added a note and a reference (add_text docstring, demo notebook) on allowed metadata field names. Thank you!

### Issue you'd like to raise. Friends, how can I return the retrieval texts(context)? My script is as follows: ```python from langchain.document_loaders import PyPDFDirectoryLoader from langchain.embeddings import OpenAIEmbeddings from langchain.text_splitter import RecursiveCharacterTextSplitter from langchain.vectorstores import FAISS from langchain.schema import Document from langchain.chat_models.openai import ChatOpenAI from langchain.prompts import ChatPromptTemplate from langchain.schema.output_parser import StrOutputParser from langchain.schema.runnable import RunnablePassthrough pdf_path = '/home/data/pdf' pdf_loader = PyPDFDirectoryLoader(pdf_path) docs = pdf_loader.load() splitter = RecursiveCharacterTextSplitter(chunk_size=256,chunk_overlap=0) split_docs = splitter.split_documents(docs) docsearch = FAISS.from_documents(split_docs,OpenAIEmbeddings()) retriever = docsearch.as_retriever() template = """Answer the question based only on the following context: {context} Question: {question} """ prompt = ChatPromptTemplate.from_template(template) model = ChatOpenAI(temperature=0.2) # RAG pipeline chain = ( {"context": retriever, "question": RunnablePassthrough()} | prompt | model | StrOutputParser() ) print(chain.invoke("How to maintain the seat belts in the Jingke model?")) ``` ### Suggestion: _No response_

### System Info This was working fine for my previous configuration, langchain v0.0.225 chromadb v0.4.7 But now neither this is working, nor the latest version of both langchain v0.0.336 chromadb v0.4.17 ### Who can help? _No response_ ### Information - [ ] The official example notebooks/scripts - [ ] My own modified scripts ### Related Components - [ ] LLMs/Chat Models - [X] 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 I have the packages installed Running these pieces of code ``` from langchain.document_loaders import TextLoader from langchain.indexes import VectorstoreIndexCreator loader = TextLoader(file_path) index = VectorstoreIndexCreator().from_loaders([loader]) # this is where I am getting the error ``` OR ``` from langchain.text_splitter import RecursiveCharacterTextSplitter from langchain.vectorstores import Chroma from langchain.embeddings.openai import OpenAIEmbeddings text_splitter = RecursiveCharacterTextSplitter() splits = text_splitter.split_documents(docs) embedding = OpenAIEmbeddings() vectordb = Chroma.from_documents( # this is where I am getting the error documents=splits, embedding=embedding, ) ``` Here is the error ``` Expected EmbeddingFunction.__call__ to have the following signature: odict_keys(['self', 'input']), got odict_keys(['self', 'args', 'kwargs'])\nPlease see https://docs.trychroma.com/embeddings for details of the EmbeddingFunction interface.\nPlease note the recent change to the EmbeddingFunction interface: https://docs.trychroma.com/migration#migration-to-0416---november-7-2023 \n ``` ### Expected behavior Earlier a chromadb instance would be created, and I would be able to query it with my prompts. That is the expected behaviour.

### Feature request Hi Guys, Here I made a new fork to [https://github.com/MetaSLAM/CyberChain](https://github.com/MetaSLAM/CyberChain), where I would like to combine the powerful Langchain ability and GPT4 into the real-world robotic challenges. My question raised here is mainly about: 1. How can I setup the Chat GPT 4 version into Langchain, where I would like to levevarge the powerful visual inference of GPT4; 2. I there any suggestion for the memory system, because the robot may travel through a large-scale environment for lifelong navigation, I would like to construct a memory system within langchain to enhance its behaviour in the long-term operation. Many thanks for your hard work, and Langchain is difinitely an impressive work. Max ### Motivation Combine real-world robotic application with the LangChain framework. ### Your contribution I will provide my research outcomes under our MetaSLAM organization (https://github.com/MetaSLAM), hope this can benefit both robotics and AI communitry, targeting for the general AI system.

This means the higher score, the higher similarity. - Actual: The scores are proportional to the the distance. ### Problem - When I call `as_retriever` function with the `score_threshold`, the behavior is wrong. Because when `score_threshold` is declared, it will filter documents that have score greater than or equal to `score_threshold` value. So the top documents that found from pgvector will be filter out while it's the most similar in fact. ### Expected behavior The returned scores from PGVector queries are proportional to the similarity. In other words, the higher score, the higher similarity.

- Fixed titles for two notebooks. They were inconsistent with other titles and clogged ToC. - Added `Upstash` description and link - Moved the authentication text up in the `Elasticsearch` nb, right after package installation. It was on the end of the page which was a wrong place.

The original notebook has the `faiss` title which is duplicated in the`faiss.jpynb`. As a result, we have two `faiss` items in the vectorstore ToC. And the first item breaks the searching order (it is placed between `A...` items). - I updated title to `Asynchronous Faiss`.

### Issue you'd like to raise. Hi, I'm trying to make a chatbot using conversationchain. The prompt takes three variables, “history” from memory, user input: "input", and another variable say variable3. But it has an error “Got unexpected prompt input variables. The prompt expects ['history', 'input', 'variable3'], but got ['history'] as inputs from memory, and input as the normal input key. ” This error doesn't occur if I'm using llmchain. So how can I prevent it if I want to use conversationchain? Thanks ### Suggestion: _No response_

### Feature request Although there are many output parsers in langchain, how to custom the output in a chain agent can not find any solutions right now--yet it may be sometimes necessary. Let's say a chain agent x, the tools are Tool1, Tool2 and Tool3, if: the output of Tool2 should be customized, and no longer be processed by GPT again, the outputs of Tool1 and Tool3 should be normal, and be processed by GPT again, in this case, no solution could be found: because the output parser is based on the agent other than any specific tools. Should this feature be satisfied? ### Motivation When multiple tools in an agent chain, and some of the tools should be output customized. ### Your contribution no

### System Info ``` langchain==0.0.335 python==3.10 ``` ### Who can help? @agola11 ### 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 - [ ] Vector Stores / Retrievers - [ ] Memory - [ ] Agents / Agent Executors - [ ] Tools / Toolkits - [X] Chains - [X] Callbacks/Tracing - [ ] Async ### Reproduction From the LCEL interface [docs](https://python.langchain.com/docs/expression_language/interface) we have the following snippet: ```python from langchain.chat_models import ChatOpenAI from langchain.prompts import ChatPromptTemplate model = ChatOpenAI() prompt = ChatPromptTemplate.from_template("tell me a joke about {topic}") chain = prompt | model for s in chain.stream({"topic": "bears"}): print(s.content, end="", flush=True) ``` From the token usage tracking [docs](https://python.langchain.com/docs/modules/model_io/chat/token_usage_tracking) we have the snippet ```python from langchain.callbacks import get_openai_callback from langchain.chat_models import ChatOpenAI llm = ChatOpenAI(model_name="gpt-4") with get_openai_callback() as cb: result = llm.invoke("Tell me a joke") print(cb) ``` that yields the following output: ``` Tokens Used: 24 Prompt Tokens: 11 Completion Tokens: 13 Successful Requests: 1 Total Cost (USD): $0.0011099999999999999 ``` I am trying to combine the two concepts in the following snippet ```python from langchain.prompts import ChatPromptTemplate from langchain.callbacks import get_openai_callback from langchain.chat_models import ChatOpenAI llm = ChatOpenAI(model_name="gpt-4") prompt = ChatPromptTemplate.from_template("tell me a joke about {topic}") chain = prompt | llm with get_openai_callback() as cb: for s in chain.stream({"topic": "bears"}): print(s.content, end="", flush=True) print(cb) ``` but get the following result: ``` Tokens Used: 0 Prompt Tokens: 0 Completion Tokens: 0 Successful Requests: 0 Total Cost (USD): $0 ``` Is token counting (and pricing) while streaming not supported at the moment? ### Expected behavior The following but with the actual values for tokens and cost. ``` Tokens Used: 0 Prompt Tokens: 0 Completion Tokens: 0 Successful Requests: 0 Total Cost (USD): $0 ```

- Fixed the title of the notebook. It created an ugly ToC element as `Activeloop DeepLake's DeepMemory + LangChain + ragas or how to get +27% on RAG recall.` - Added Activeloop description - improved consistency in text - fixed ToC (it was using HTML tagas that break left-side in-page ToC). Now in-page ToC works

Hi! This short PR aims at: * Fixing `OpenAIEmbeddings`' check on `chunk_size` when used with Azure OpenAI (thus with openai < 1.0). Azure OpenAI embeddings support at most 16 chunks per batch, I believe we are supposed to take the min between the passed value/default value and 16, not the max - which, I suppose, was introduced by accident while refactoring the previous version of this check from this other PR of mine: #10707 * Porting this fix to the newest class (`AzureOpenAIEmbeddings`) for openai >= 1.0 This fixes #13539 (closed but the issue persists). @baskaryan @hwchase17

- Fixed headers (was more then 1 Titles) - Removed security token value. It was OK to have it, because it is temporary token, but the automatic security swippers raise warnings on that. - Added `ClickUp` service description and link.

### System Info Langchain 0.0.335 ### Who can help? _No response_ ### Information - [ ] The official example notebooks/scripts - [X] My own modified scripts ### Related Components - [X] LLMs/Chat Models - [ ] Embedding Models - [ ] Prompts / Prompt Templates / Prompt Selectors - [ ] Output Parsers - [ ] Document Loaders - [ ] Vector Stores / Retrievers - [ ] Memory - [ ] Agents / Agent Executors - [ ] Tools / Toolkits - [X] Chains - [ ] Callbacks/Tracing - [ ] Async ### Reproduction When status code is not 200, [TextGen ](https://github.com/langchain-ai/langchain/blob/master/libs/langchain/langchain/llms/textgen.py#L223)only prints the code and returns an empty string. This is a problem if I want to use TextGen `with_retry()` and I want to retry non 200 responses such as 5xx. - If I edit the textgen.py source code myself and raise an Exception [here](https://github.com/langchain-ai/langchain/blob/master/libs/langchain/langchain/llms/textgen.py#L223), then my `with_retry()` works as desired. I tried to handle this by raising an empty string error in my Output Parser, but the TextGen `with_retry()` is not triggering. ### Expected behavior I'd like TextGen to raise an Exception when the status code is not 200. Perhaps consider using the `HTTPError` from `requests` package.

### Issue you'd like to raise. Hi, I have been learning LangChain for the last month and I have been struggling in the last week to "_guarantee_" `ConversationalRetrievalChain` only answers based on the knowledge added on embeddings. I don't know if I am missing some LangChain configuration or if it is just a matter of tuning my prompt. I will add my code here (simplified, not the actual one, but I will try to preserve everything important). ``` chat = AzureChatOpenAI( deployment_name="chat", model_name="gpt-3.5-turbo", openai_api_version=os.getenv('OPENAI_API_VERSION'), openai_api_key=os.getenv('OPENAI_API_KEY'), openai_api_base=os.getenv('OPENAI_API_BASE'), openai_api_type="azure", temperature=0 ) embeddings = OpenAIEmbeddings(deployment_id="text-embedding-ada-002", chunk_size=1) acs = AzureSearch(azure_search_endpoint=os.getenv('AZURE_COGNITIVE_SEARCH_SERVICE_NAME'), azure_search_key=os.getenv('AZURE_COGNITIVE_SEARCH_API_KEY'), index_name=os.getenv('AZURE_COGNITIVE_SEARCH_INDEX_NAME'), embedding_function=embeddings.embed_query) custom_template = """You work for CompanyX which sells things located in United States. If you don't know the answer, just say that you don't. Don't try to make up an answer. Base your questions only on the knowledge provided here. Do not use any outside knowledge. Given the following chat history and a follow up question, rephrase the follow up question to be a standalone question, in its original language. Chat History: {chat_history} Follow Up Input: {question} Standalone question: """ CUSTOM_QUESTION_PROMPT = PromptTemplate.from_template(custom_template) memory = ConversationBufferMemory(memory_key="chat_history", input_key="question", return_messages=True) qa = ConversationalRetrievalChain.from_llm( llm=chat, retriever=acs.as_retriever(), condense_question_prompt=CUSTOM_QUESTION_PROMPT, memory=memory ) ``` When I ask it something like `qa({"question": "What is an elephant?"})` it still answers it, although it is totally unrelated to the knowledge base added to the AzureSearch via embeddings. I tried different `condense_question_prompt`, with different results, but nothing near _good_. I've been reading the documentation and API for the last 3 weeks, but nothing else seems to help in this case. I'd appreciate any suggestions. ### Suggestion: _No response_

### Feature request Add IDE auto-complete to `langchain.llm` module Currently, IntelliJ-based IDEs (PyCharm) interpret an LLM model to be `typing.Any`. Below is an example for the `GPT4All` package ![image](https://github.com/langchain-ai/langchain/assets/49741340/27d699a7-d8d3-44f0-bb32-96d798a63a37) ### Motivation Not having auto-complete on a `LLM` class can be a bit frustrating as a Python developer who works on an IntelliJ product. I've been performing a more direct import of the LLM models to handle this instead: ```python from langchain.llms.gpt4all import GPT4All ``` Adding support for the `langchain.llms` API would improve the developer experience with the top level `langchain.llms` API ### Your contribution The existing implementation uses a lazy-loading technique implemented in #11237 to speed up imports. Maintaining this performance is important for whatever solution is implemented. I believe this can be achieved with some imports behind an `if TYPE_CHECKING` block. If the below `Proposed Implementation` is acceptable I'd be happy to open a PR to add this functionality. <details><summary>Current Implementation</summary> <p> `langchain.llms.__init__.py` (abbreviated) ```python from typing import Any, Callable, Dict, Type from langchain.llms.base import BaseLLM def _import_anthropic() -> Any: from langchain.llms.anthropic import Anthropic return Anthropic def _import_gpt4all() -> Any: from langchain.llms.gpt4all import GPT4All return GPT4All def __getattr__(name: str) -> Any: if name == "Anthropic": return _import_anthropic() elif name == "GPT4All": return _import_gpt4all() else: raise AttributeError(f"Could not find: {name}") __all__ = [ "Anthropic", "GPT4All", ] ``` </p> </details> <details><summary>Proposed Implementation</summary> <p> `langchain.llms.__init__.py` (abbreviated) ```python from typing import Any, Callable, Dict, Type, TYPE_CHECKING from langchain.llms.base import BaseLLM if TYPE_CHECKING: from langchain.llms.anthropic import Anthropic from langchain.llms.gpt4all import GPT4All def _import_anthropic() -> "Anthropic": from langchain.llms.anthropic import Anthropic return Anthropic def _import_gpt4all() -> "GPT4All": from langchain.llms.gpt4all import GPT4All return GPT4All def __getattr__(name: str) -> "BaseLLM": if name == "Anthropic": return _import_anthropic() elif name == "GPT4All": return _import_gpt4all() else: raise AttributeError(f"Could not find: {name}") __all__ = [ "Anthropic", "GPT4All", ] ``` </p> </details> <details><summary>IntelliJ Screenshot</summary> <p> Here's a screenshot after implementing the above `Proposed Implementation` <img width="588" alt="image" src="https://github.com/langchain-ai/langchain/assets/49741340/1647f3b5-238e-4137-8fa4-f30a2234fdb0"> </p> </details>

### System Info Name: langchain Version: 0.0.327 Name: chromadb Version: 0.4.8 Summary: Chroma. ### Who can help? @hwchase17 I believe the chromadb don't close the file handle during persistence making it difficult to use it on cloud services like Modal Labs. What about adding a close method or similar to make sure this doesn't happen? ### 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 I am using ModalLabs with a simple example: ``` @stub.function(volumes={CHROMA_DIR: stub.volume}) def test_chroma(): import chromadb from importlib.metadata import version print("ChromaDB: %s" % version('chromadb')) # Initialize ChromaDB client client = chromadb.PersistentClient(path=SENTENCE_DIR.as_posix()) # Create the collection neo_collection = client.create_collection(name="neo") # Adding raw documents neo_collection.add( documents=["I know kung fu.", "There is no spoon."], ids=["quote_1", "quote_2"] ) # Counting items in a collection item_count = neo_collection.count() print(f"Count of items in collection: {item_count}") stub.volume.commit() ``` Error: `grpclib.exceptions.GRPCError: (<Status.FAILED_PRECONDITION: 9>, 'there are open files preventing the operation', None) ` ### Expected behavior There shouldn't be any open file handles.

Fixes #13407. This workaround consists in letting the RunnableLambda create its self.afunc from its self.func when self.afunc is not provided; the change has no dependency. <!-- Thank you for contributing to LangChain!

### System Info langchain on master branch ### Who can help? _No response_ ### 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 - [ ] Vector Stores / Retrievers - [ ] Memory - [ ] Agents / Agent Executors - [ ] Tools / Toolkits - [X] Chains - [ ] Callbacks/Tracing - [X] Async ### Reproduction ``` from langchain.schema.runnable import RunnableLambda import asyncio def idchain_sync(__input): print(f'sync chain call: {__input}') return __input async def idchain_async(__input): print(f'async chain call: {__input}') return __input idchain = RunnableLambda(func=idchain_sync,afunc=idchain_async) def func(__input): return idchain asyncio.run(RunnableLambda(func).ainvoke('toto')) #printss 'sync chain call: toto' instead of 'async chain call: toto' ``` ### Expected behavior LCEL's route can cause chains to be silently run synchronously, while the user uses ainvoke... When calling a RunnableLambda A returning a chain B with ainvoke, we would expect the new chain B to be called with ainvoke; However, if the function provided to RunnableLambda A is not async, then the chain B will be called with invoke, silently causing all the rest of the chain to be called synchronously.

### Issue you'd like to raise. Hi there, I am doing a research on creating a PDF reader AI which can answer users' questions based on the PDF uploaded and the prompt user entered. I got it so far with using the OpenAI package but now want's to make it more advance by using ChatOpenAI with the LangChain Schema package (SystemMessage, HumanMessage, and AIMessage). I am kinda lost on where I should start and make the adjustments. Could you help me on that? Below is my code so far: ## Imports import streamlit as st import os from apikey import apikey import pickle from PyPDF2 import PdfReader from streamlit_extras.add_vertical_space import add_vertical_space from langchain.text_splitter import RecursiveCharacterTextSplitter from langchain.embeddings.openai import OpenAIEmbeddings from langchain.vectorstores import FAISS from langchain.llms import OpenAI from langchain.chains.question_answering import load_qa_chain from langchain.callbacks import get_openai_callback from langchain.chat_models import ChatOpenAI from langchain.schema import (SystemMessage, HumanMessage, AIMessage) os.environ['OPENAI_API_KEY'] = apikey ## User Interface # Side Bar with st.sidebar: st.title('🚀 Zi-GPT Version 2.0') st.markdown(''' ## About This app is an LLM-powered chatbot built using: - [Streamlit](https://streamlit.io/) - [LangChain](https://python.langchain.com/) - [OpenAI](https://platform.openai.com/docs/models) LLM model ''') add_vertical_space(5) st.write('Made with ❤️ by Zi') # Main Page def main(): st.header("Zi's PDF Helper: Chat with PDF") # upload a PDF file pdf = st.file_uploader("Please upload your PDF here", type='pdf') # st.write(pdf) # read PDF if pdf is not None: pdf_reader = PdfReader(pdf) # split document into chunks # also can use text split: good for PDFs that do not contains charts and visuals sections = [] for page in pdf_reader.pages: # Split the page text by paragraphs (assuming two newlines indicate a new paragraph) page_sections = page.extract_text().split('\n\n') sections.extend(page_sections) chunks = sections # st.write(chunks) # embeddings file_name = pdf.name[:-4] # comvert into pickle file # wb: open in binary mode # rb: read the file # Note: only create new vectors for new files updated if os.path.exists(f"{file_name}.pkl"): with open(f"{file_name}.pkl", "rb") as f: VectorStore = pickle.load(f) st.write('Embeddings Loaded from the Disk') else: embeddings = OpenAIEmbeddings(model="text-embedding-ada-002") VectorStore = FAISS.from_texts(chunks,embedding=embeddings) with open(f"{file_name}.pkl", "wb") as f: pickle.dump(VectorStore, f) st.write('Embeddings Computation Completed') # Create chat history if pdf: # generate chat history chat_history_file = f"{pdf.name}_chat_history.pkl" # load history if exist if os.path.exists(chat_history_file): with open(chat_history_file, "rb") as f: chat_history = pickle.load(f) else: chat_history = [] # Initialize chat_history in session_state if not present if 'chat_history' not in st.session_state: st.session_state.chat_history = [] # Check if 'prompt' is in session state if 'last_input' not in st.session_state: st.session_state.last_input = '' # User Input current_prompt = st.session_state.get('user_input', '') prompt_placeholder = st.empty() prompt = prompt_placeholder.text_area("Ask questions about your PDF:", value=current_prompt, placeholder="Send a message", key="user_input") submit_button = st.button("Submit") if submit_button and prompt: # Update the last input in session state st.session_state.last_input = prompt docs = VectorStore.similarity_search(query=prompt, k=3) #llm = OpenAI(temperature=0.9, model_name='gpt-3.5-turbo') chat = ChatOpenAI(model='gpt-3.5-turbo', temperature=0.7) chain = load_qa_chain(llm=chat, chain_type="stuff") with get_openai_callback() as cb: response = chain.run(input_documents=docs, question=prompt) print(cb) # st.write(response) # st.write(docs) # Add to chat history st.session_state.chat_history.append((prompt, response)) # Save chat history with open(chat_history_file, "wb") as f: pickle.dump(st.session_state.chat_history, f) # Clear the input after processing prompt_placeholder.text_area("Ask questions about your PDF:", value='', placeholder="Send a message", key="pdf_prompt") # Display the entire chat chat_content = "" for user_msg, bot_resp in st.session_state.chat_history: chat_content += f"<div style='background-color: #222222; color: white; padding: 10px;'>**You:** {user_msg}</div>" chat_content += f"<div style='background-color: #333333; color: white; padding: 10px;'>**Zi GPT:** {bot_resp}</div>" st.markdown(chat_content, unsafe_allow_html=True) if __name__ == '__main__': main() ### Suggestion: _No response_

Hi 👋 We are working with Llama2 on Bedrock, and would like to add it to Langchain. We saw a [pull request](https://github.com/langchain-ai/langchain/pull/13322) to add it to the `llm.Bedrock` class, but since it concerns a chat model, we would like to add it to `BedrockChat` as well. - **Description:** Add support for Llama2 to `BedrockChat` in `chat_models` - **Issue:** the issue # it fixes (if applicable) [#13316](https://github.com/langchain-ai/langchain/issues/13316) - **Dependencies:** any dependencies required for this change `None` - **Tag maintainer:** / - **Twitter handle:** `@SimonBockaert @WouterDurnez`

### Feature request Currently no support for multi-modal embeddings from VertexAI exists. However, I did stumble upon this experimental implementation of [GoogleVertexAIMultimodalEmbeddings](https://js.langchain.com/docs/modules/data_connection/experimental/multimodal_embeddings/google_vertex_ai) in LangChain for Javascript. Hence, I think this would also be a very nice feature to implement in the Python version of LangChain. ### Motivation Using multi-modal embeddings could positively affect applications that rely on information of different modalities. One example could be product search in a web catalogue. Since more cloud providers are making [endpoints for multi-modal embeddings](https://cloud.google.com/vertex-ai/docs/generative-ai/embeddings/get-multimodal-embeddings) available, it makes sense to incorporate these into LangChain as well. The embeddings of these endpoints could be stored in vector stores and hence be used in downstream applications that are built using LangChain. ### Your contribution I can contribute to this feature.

### Feature request Elastic supports natively to have multiple DenseVectors in a document, which can be selected during query time / search. The langchain vector search interface enables to pass additional keyword args. But at the moment, the implementation of _search in the ElasticSearch implementation does not consider the `vector_query_field` variable, which could be passed through the kwargs. Furthermore, there should be a solution, to allow a document to have multiple text fields that get passed as a queryable vector, not just the standard text field. ### Motivation If you have multiple vector fields in one index, this feature could simplify the query of the right one, like it's natively allowed in Elastic. In the current implementation one would need to add additional vector fields in the metadata and change the `vector_query_field` of ElasticSearchStore the whole class every time before you call the search. This is not a clean solution and I would vote for a more generic and clean solution. ### Your contribution I could help by implementing this issue, although I need to state that I am not an expert in Elastic. I saw this issue when we tried to use an existing index in Elastic to add and retrieve Documents within the Langchain Framework.

### System Info Not relevant. ### Who can help? @hwchase17 @agola11 ### Information - [ ] The official example notebooks/scripts - [ ] My own modified scripts ### Related Components - [X] LLMs/Chat Models - [ ] Embedding Models - [ ] Prompts / Prompt Templates / Prompt Selectors - [ ] Output Parsers - [ ] Document Loaders - [ ] Vector Stores / Retrievers - [ ] Memory - [ ] Agents / Agent Executors - [ ] Tools / Toolkits - [ ] Chains - [ ] Callbacks/Tracing - [ ] Async ### Reproduction Use any LLM relying on stop words with special regex characters. For example instanciate a `HuggingFacePipeline` LLM instance with [openchat](https://huggingface.co/openchat/openchat_3.5) model. This model uses `<|end_of_turn|>` stop words. Since the `llms.utils.enforce_stop_tokens()` function doesn't escape the provided stop words strings the `|` chars are interpreted as part of the regex instead of the stop word. So in this case any single `<` chars in the output would trigger the split. ### Expected behavior Stop words should be escaped with `re.escape()` so the split only happens on the complete words.

### Feature request Make `Message` and/or `Memory` to support `Timestamp` ### Motivation To provide context and clarity regarding the timing of conversation. This can be helpful for reference and coordination, especially when discussing time-sensitive topics. I noticed that [one agent in opengpts](https://opengpts-example-vz4y4ooboq-uc.a.run.app/) has supported this feature. ### Your contribution I have not made a clear outline of adding the `Timestamps` feature. The following is some possible ways to support it for discussion: Proposal 1: Add `Timestamps` to `Message Schema`. This way every `Memory Entity` should support `Timestamps`. Proposal 2: Create a new `TimestampedMemory`. This way has a better backward compatibility.

### System Info Windows 11, Langchain 0.0327, Python 3.10. The Doc2txtLoader does not work for web paths, as a PermissionError occurs when self.tempfile attempts to write content to the tempfile: if not os.path.isfile(self.file_path) and self._is_valid_url(self.file_path): r = requests.get(self.file_path) if r.status_code != 200: raise ValueError( "Check the url of your file; returned status code %s" % r.status_code ) self.web_path = self.file_path self.temp_file = tempfile.NamedTemporaryFile() **self.temp_file.write(r.content)** self.file_path = self.temp_file.name elif not os.path.isfile(self.file_path): raise ValueError("File path %s is not a valid file or url" % self.file_path) It produces a Permission Error: _[Errno 13] Permission denied:_ as the file is already open, and will be deleted on close. I can work around this by replacing this section of the code with the following: if not os.path.isfile(self.file_path) and self._is_valid_url(self.file_path): self.temp_dir = tempfile.TemporaryDirectory() _, suffix = os.path.splitext(self.file_path) temp_pdf = os.path.join(self.temp_dir.name, f"tmp{suffix}") self.web_path = self.file_path if not self._is_s3_url(self.file_path): r = requests.get(self.file_path, headers=self.headers) if r.status_code != 200: raise ValueError( "Check the url of your file; returned status code %s" % r.status_code ) with open(temp_pdf, mode="wb") as f: f.write(r.content) self.file_path = str(temp_pdf) elif not os.path.isfile(self.file_path): raise ValueError("File path %s is not a valid file or url" % self.file_path) This is the method that works for the PDF loader. The workaround is fine for now but will cause a problem if I need to update the langchain version any time in the future. ### Who can help? @hwchase17 @eyurtsev ### Information - [X] The official example notebooks/scripts - [ ] 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 from langchain.document_loaders import Docx2txtLoader loader = Docx2txtLoader("https://file-examples.com/wp-content/storage/2017/02/file-sample_100kB.docx") doc = loader.load()[0] Traceback (most recent call last): File "C:\Program Files\JetBrains\PyCharm Community Edition 2022.3.2\plugins\python-ce\helpers\pydev\pydevconsole.py", line 364, in runcode coro = func() File "<input>", line 3, in <module> File "C:\Users\crawleyb\PycharmProjects\SharepointGPT\venv\lib\site-packages\langchain\document_loaders\word_document.py", line 55, in load return [ File "C:\Users\crawleyb\PycharmProjects\SharepointGPT\venv\lib\site-packages\docx2txt\docx2txt.py", line 76, in process zipf = zipfile.ZipFile(docx) File "C:\Program Files\WindowsApps\PythonSoftwareFoundation.Python.3.10_3.10.3056.0_x64__qbz5n2kfra8p0\lib\zipfile.py", line 1251, in __init__ self.fp = io.open(file, filemode) PermissionError: [Errno 13] Permission denied: 'C:\\Users\\ ### Expected behavior The DocumentLoader should be able to get the contents of the docx file, loader.load()[0] should return a Document object.

### Issue with current documentation: I'm trying to work through the streaming parameters around run_manager and callbacks. Here's a minimal setup of what I'm trying to establish ``` class MyTool(BaseTool) name: "my_extra_tool" async def _arun(self, query: str, run_manager: Optional[AsyncCallbackManagerForToolRun] = None) -> str: """Use the tool asynchronously.""" nested_manager = run_manager.get_child() # run_manager doesn't have an `on_llm_start` method, only supports `on_tool_end` / `on_tool_error` and `on_text` (which has no callback in LangchainTracer llm_run_manager = await nested_manager.on_llm_start({"llm": self.llm, "name": self.name+"_substep"}, prompts=[query]) # need to give # do_stuff, results in main_response main_response = "<gets created in the tool, might be part of streaming output in the future>" await llm_run_manager[0].on_llm_new_token(main_response) # can't use llm_run_manager directly as it's a list await llm_run_manager[0].on_llm_end(response=main_response) ``` I'm seeing that on_llm_new_token callback is being called in my custom callback handler, but I don't see the response in Langsmith. The docs aren't fully clear on how to make sure these run_ids should be propagated. ### Idea or request for content: It would be fantastic to have a detailed example of how to correctly nest runs with arbitrary tools.

### System Info Langchain version: 0.0.321 Python: 3.10 ### Who can help? @hwchase17 ### Information - [ ] The official example notebooks/scripts - [ ] My own modified scripts ### Related Components - [ ] LLMs/Chat Models - [ ] Embedding Models - [ ] Prompts / Prompt Templates / Prompt Selectors - [ ] Output Parsers - [ ] Document Loaders - [ ] Vector Stores / Retrievers - [ ] Memory - [ ] Agents / Agent Executors - [ ] Tools / Toolkits - [X] Chains - [ ] Callbacks/Tracing - [ ] Async ### Reproduction I am using Langchain to generate and execute SQL queries for MySql database. The SQL Query generated is enclosed in single quotes Generate SQL Query: **'**"SELECT * FROM EMPLOYEE WHERE ID = 123"**'** Expected SQL Query: "SELECT * FROM EMPLOYEE WHERE ID = 123" Hence though the query is correct, sql alchemy is unable to execute query and gives Programming error (pymysql.err.ProgrammingError) (1064, 'You have an error in your SQL syntax; check the manual that corresponds to your MySQL server version for the right syntax to use ### Expected behavior Expected SQL Query should be without enclosing single quotes. I did some debugging as looks like we get single quotes while invoking predict method of LLM - https://github.com/langchain-ai/langchain/blob/master/libs/experimental/langchain_experimental/sql/base.py#L156

### Issue you'd like to raise. Hi guys, Here is the situation, I have 3 tools to use one by one. But, the outputs of which are not in the same types. Say: Tool 1: output normally, and can be further thought by GPT in the chain, Tool 2: output specially, which means the output should not be thought further by GPT again, because in that way the output format and data will be not correctly, Tool 3: output normally, like Tool 1. In this way, I found it hard to get the correct answer for myself. If all the tools are set to return_direct=False, the answer to Tool 2 will not be right, and if I set return_dircect=True, the chain of Tools 1->2->3 would be lost... What should I do? Any help will be highly appreciated. Best ### Suggestion: _No response_

- **Description:** - Fixes a `key_prefix` bug where passing it in on `Redis.from_existing(...)` did not work properly. Updates doc strings accordingly. - Updates Redis filter classes logic with best practices on typing, string formatting, and handling "empty" filters. - Fixes a bug that would prevent multiple tag filters from being applied together in some scenarios. - Added a whole new filter unit testing module. Also updated code formatting for a number of modules that were failing the `make` commands. - **Issue:** N/A - **Dependencies:** N/A - **Tag maintainer:** @baskaryan - **Twitter handle:** @tchutch94

- **Description:** Recently, this was introduced: https://github.com/langchain-ai/langchain/pull/10707 However, the changes are not taking effect unless you create the AzureOpenAIEmbeddings class with parameter openai_api_type="azure".. In the code it's already getting set by default if openAI version > 1 but it's never getting accessed when the embed_documents is actually happening because it was never surfaced up - **Issue:** Not so much an issue but leveraging existing default code of api type of azure when used. - **Twitter handle:** @kevin_neum

My thought is that the ==version would prevent pip from finding the package on regular [pypi.org](http://pypi.org/), so it would look at [test.pypi.org](http://test.pypi.org/) for that. Otherwise it'll pull package from [pypi.org](http://pypi.org/) (e.g. sub deps) Right now, the cli release is failing because it's going to test.pypi.org by default, so it finds this incorrect FASTAPI package instead of the real one: https://test.pypi.org/project/FASTAPI/

### System Info LangChain version: Platform: WSL for Windows (Linux 983G3J3 5.15.90.1-microsoft-standard-WSL2) Python version: 3.10.6 ### Who can help? @agola11 ### Information - [ ] The official example notebooks/scripts - [X] My own modified scripts ### Related Components - [X] LLMs/Chat Models - [ ] Embedding Models - [ ] Prompts / Prompt Templates / Prompt Selectors - [ ] Output Parsers - [ ] Document Loaders - [ ] Vector Stores / Retrievers - [ ] Memory - [ ] Agents / Agent Executors - [ ] Tools / Toolkits - [ ] Chains - [ ] Callbacks/Tracing - [ ] Async ### Reproduction 1a. Create a project in GCP and deploy an open source model from Vertex AI Model Garden (follow the provided Colab notebook to deploy to an endpoint) 1b. Instantiate a VertexAIModelGarden object ```python llm = VertexAIModelGarden(project=PROJECT_ID, endpoint_id=ENDPOINT_ID) ``` 2. Create a prompt string ```python prompt = "This is an example prompt" ``` 3. Call the generate method on the VertexAIModelGarden object ```python llm.generate([prompt]) ``` 4. The following error will be produced: ```python ../python3.10/site-packages/langchain/llms/vertexai.py", line 452, in <listcomp> [Generation(text=prediction[self.result_arg]) for prediction in result] TypeError: string indices must be integers ``` ### Expected behavior Expecting the generate method to return an LLMResult object that contains the model's response in the 'generations' property In order to align with Vertex AI api the _generate method should iterate through response.predictions and set text property of Generation object to the iterator variable since response.predictions is a list data type that contains the output strings. ```python for result in response.predictions: generations.append( [Generation(text=result)] ) ```

- **Description:** As I was working through bedrock llm for RetreivalQAChain I noticed that the imports were wrong and is corrected for documentation. - **Issue:** As mentioned in the documentation for langchain. The import says from `langchain.llms import Bedrock` which should rather be `from langchain.llms.bedrock import Bedrock` - **Dependencies:** None

- **Description:** Adds `limit_to_domains` param to the APIChain based tools (open_meteo, TMDB, podcast_docs, and news_api) - **Issue:** I didn't open an issue, but after upgrading to 0.0.328 using these tools would throw an error. - **Dependencies:** N/A - **Tag maintainer:** @baskaryan **Note**: I included the trailing / simply because the docs here did https://github.com/langchain-ai/langchain/blob/fc886cc3039c2479bb13287f48fcbdb097a44c70/docs/docs/use_cases/apis.ipynb#L246 , but I checked the code and it is using `urlparse`. SoI followed the docs since it comes down to stylee.

### System Info after getting million embedding records in postgres, everything became ridiculously slow and postgres cpu usage went to 100% fix was simple: ``` CREATE INDEX CONCURRENTLY langchain_pg_embedding_collection_id ON langchain_pg_embedding(collection_id); CREATE INDEX CONCURRENTLY langchain_pg_collection_name ON langchain_pg_collection(name); ``` I think it's important to include index creation in basic setup. ### Who can help? _No response_ ### Information - [ ] The official example notebooks/scripts - [ ] My own modified scripts ### Related Components - [ ] LLMs/Chat Models - [ ] Embedding Models - [ ] Prompts / Prompt Templates / Prompt Selectors - [ ] Output Parsers - [ ] Document Loaders - [ ] Vector Stores / Retrievers - [ ] Memory - [ ] Agents / Agent Executors - [ ] Tools / Toolkits - [ ] Chains - [ ] Callbacks/Tracing - [ ] Async ### Reproduction Just run PGVector, and it will create tables without indices. ### Expected behavior Should create indices

**Description:** Adds the ability to pass filters and other search_kwargs to a vector store when *calling* a conversational retriever . (#9195) Existing functionality allows setting the search_kwargs only when *constructing* the retriever - which limits the ability to create a single retriever then alter filters during chat sessions. My use case (backed by the others in the Issue) is to be able to ingest documents into a vector database with different 'tags', then during a long-running RAG0-based chat session, specify the tags to filter ingested documents on with each question. The existing support for search_kwargs is still useful - args like 'k', the number of results, are likely to be definitely determined at construction time. Hence this fix *merges* the search_kwargs provided with the query with any that were set during construction. That is: query-time values *override* construction-time values, but only those with the same key. Hence you can set 'k', 'score_threshold', etc, during construction, then pass in a custom 'filter' with the query. Query-time search_kwargs are provided in the `inputs` parameter, but are not listed in the input_keys, since they are not mandatory. This preserves compatibility, and makes sense, given the search_kwargs, very much are inputs. The documentation is updated with an example on the vector_db_qa.mdx page. Details on the rationale behind this PR: 1. Many of the vector store implementations take “filter” as a parameter in their similarity_search (chroma, elastic, pgvector, open_search), and some, like weaviate, take more complex kwargs, accepting in them “where_filter”. We need a way to pass down arguments for these parameters from the original __call__ method on the base chain, in such a way as they get to - and only to - the vector stores that can use them. 2. The generic VectorStoreRetriever has a search_kwargs field (Pydantic) that is intended to hold just this sort of parameter, and passes it into similarty_search() (and other search methods). But is limited in that it can only be set when the VectorRetriever is constructed. 3. The abstract BaseRetriever._get_relevant_documents doesn’t take extra args, but BaseRetriever allows for the concrete implementations in different retrievers to have extra args (which only just slightly freaks me out as an old OO Java programmer :)). BaseRetriever detects this and sets _expects_other_args to True which causes it to pass on kwargs from its get_relevant_documents() method to the specific retrievers _get_relevant_documents implementation. So… to get our filter down where it’s needed, we need to get it in a more dynamic search_kwargs dictionary, and get that merged with the one passed in from VectorStoreRetriever, without interfering with the base retriever. For this we need one change to VectoreStoreRetriever: - add a search_kwargs dictionary to its _get_relevant_documents method - merge that with the base search kwargs (dictionary update - to override, treating the construction-time search_kwargs as defaults We have to change one more class though, to get the search_kwargs into the get_relevant_documents incoming kwargs parameter: we can do that in ConversationalRetrievalChain._get_docs which currently does not call it with any kwargs. But _get_docs just happens to get the inputs dictionary from which history and question are taken, which is passed in from the original __call__. Hence we: - Modifiy ConversationalRetrievalChain._get_docs to retrieve the search_kwargs, if there are any, from the inputs[] list and add them to the kwargs going into get_relevant_documents So, we can put search_kwargs in inputs- because they are just as much inputs as the question and chat_history, then we can extract them in _get_docs and pass them into get_relevant_documents, and we get them where they need to go with only two changes. The modifications needed for base retrievers is slightly different, but similar enough. **Issue:** Passing filter through ConversationalRetrievalChain to the underlying vector store #9195 **Tag maintainer:** @baskaryan

### Feature request Supplying a not default parameter to a model is not something that will require always showing a warning. It should be easy to suppress that specific warning. ### Motivation The logging gets full of those warnings just because you are supplying not default parameters such as "top_p", "frequency_penalty" or "presence_penalty".

This version of `ruff` is the one we'll be using to lint the docs and cookbooks (#12677), so I'm making it used everywhere else too.
