### System Info langchain 0.0.335 macOS 14.1.1 / Windows 10.0.19045 Python 3.11.6 / 3.10.9 ### Who can help? @naveentatikonda ### 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 Install dependencies ```shell pip install langchain opensearch-py boto3 ``` Import packages ```python import boto3 from langchain.embeddings import FakeEmbeddings from langchain.vectorstores.opensearch_vector_search import OpenSearchVectorSearch from opensearchpy import RequestsAWSV4SignerAuth, RequestsHttpConnection ``` Create AOSS auth ```python boto_session = boto3.Session() aoss_auth = RequestsAWSV4SignerAuth(credentials=boto_session.get_credentials(), region=boto_session.region_name, service="aoss") ``` Create AOSS vector search class ```python embeddings = FakeEmbeddings(size=42) database = OpenSearchVectorSearch( opensearch_url="https://some_aoss_endpoint:443", http_auth=aoss_auth, connection_class=RequestsHttpConnection, index_name="test", embedding_function=embeddings, ``` Check if AOSS vector search identifies itself as AOSS ```python database.is_aoss ``` Returns **False** ### Expected behavior AOSS should correctly identify itself as AOSS given the configuration above, which means that `database.is_aoss` should return **True** in this case. The issue is related to how the internal `_is_aoss_enabled` method works: ```python def _is_aoss_enabled(http_auth: Any) -> bool: """Check if the service is http_auth is set as `aoss`.""" if ( http_auth is not None and hasattr(http_auth, "service") and http_auth.service == "aoss" ): return True return False ``` The `RequestsAWSV4SignerAuth` does not expose the _service_ property directly, but via the _signer_ attribute. In order to respect that, `is_aoss_enabled` should be adapted as following: ```python def _is_aoss_enabled(http_auth: Any) -> bool: """Check if the service set via http_auth equals `aoss`.""" if http_auth is not None: if hasattr(http_auth, "service") and http_auth.service == "aoss": return True elif hasattr(http_auth, "signer") and http_auth.signer.service == "aoss": return True else: return False return False ```

### System Info * Windows 11 Home (build 22621.2715) * Python 3.12.0 * Clean virtual environment using Poetry with following dependencies: ``` python = "3.12.0" langchain = "0.0.344" spacy = "3.7.2" spacy-llm = "0.6.4" ``` ### Who can help? @h3l As the creator of the pull request where VolcEngine was introduced @baskaryan As tag handler of that pull request ### 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 Anything that triggers spaCy's registry to make an inventory, for example: ```python import spacy spacy.blank("en") ``` With the last part of the Traceback being: ``` File "PROJECT_FOLDER\.venv\Lib\site-packages\langchain\llms\__init__.py", line 699, in __getattr__ k: v() for k, v in get_type_to_cls_dict().items() ^^^ File "PROJECT_FOLDER\.venv\Lib\site-packages\langchain_core\load\serializable.py", line 97, in __init__ super().__init__(**kwargs) File "PROJECT_FOLDER\.venv\Lib\site-packages\pydantic\v1\main.py", line 341, in __init__ raise validation_error pydantic.v1.error_wrappers.ValidationError: 1 validation error for VolcEngineMaasLLM __root__ Did not find volc_engine_maas_ak, please add an environment variable `VOLC_ACCESSKEY` which contains it, or pass `volc_engine_maas_ak` as a named parameter. (type=value_error) ``` #### What I think causes this I am quite certain that this is caused by [`langchain.llms.__init__.py:869 (for commit b161f30)`](https://github.com/langchain-ai/langchain/blob/b161f302ff56a14d8d0331cbec4a3efa23d06e1a/libs/langchain/langchain/llms/__init__.py#L869C51-L869C51): ```python def get_type_to_cls_dict() -> Dict[str, Callable[[], Type[BaseLLM]]]: return { "ai21": _import_ai21, "aleph_alpha": _import_aleph_alpha, "amazon_api_gateway": _import_amazon_api_gateway, ... "qianfan_endpoint": _import_baidu_qianfan_endpoint, "yandex_gpt": _import_yandex_gpt, # Line below is the only that actually calls the import function, returning a class instead of an import function "VolcEngineMaasLLM": _import_volcengine_maas(), } ``` The Volc Engine Maas LLM is the only in this dict to actually call the import function, while all other entries only the function itself, and do not call it. ### Expected behavior Class to type dict only returns import functions, not actual classes: ```python def get_type_to_cls_dict() -> Dict[str, Callable[[], Type[BaseLLM]]]: return { "ai21": _import_ai21, "aleph_alpha": _import_aleph_alpha, "amazon_api_gateway": _import_amazon_api_gateway, ... "qianfan_endpoint": _import_baidu_qianfan_endpoint, "yandex_gpt": _import_yandex_gpt, # What I think would be correct (now without function call) "VolcEngineMaasLLM": _import_volcengine_maas, } ``` Unfortunately I don't have time to put in a PR myself, but I hope this helps finding the solution!

**Description:** By combining the document timestamp refresh within a single call to update(), this enables batching of multiple documents in a single SQL statement. This is important for non-local databases where tens of milliseconds has a huge impact on performance when doing document-by-document SQL statements. **Issue:** #11935 **Dependencies:** None **Tag maintainer:** @eyurtsev

- **Description:** to support not only publicly available Hugging Face endpoints, but also protected ones (created with "Inference Endpoints" Hugging Face feature), I have added ability to specify custom api_url. But if not specified, default behaviour won't change - **Issue:** #9181, - **Dependencies:** no extra dependencies

### Feature request Currently, the ConversationSummaryBufferMemory only supports the GPT2TokenizerFast and there is no option to pass a custom tokenizer. Different models have different corresponding tokenizers, so it makes sense to allow the option to specify a custom tokenizer. The tokenizer fetching is implemented in langchain/schema/language_model.py: @lru_cache(maxsize=None) # Cache the tokenizer def get_tokenizer() -> Any: try: from transformers import GPT2TokenizerFast except ImportError: raise ImportError( "Could not import transformers python package. " "This is needed in order to calculate get_token_ids. " "Please install it with `pip install transformers`." ) # create a GPT-2 tokenizer instance return GPT2TokenizerFast.from_pretrained("gpt2") ### Motivation Using the exact tokenizer which the model uses will help in being more accurate in the context summarization cutoff. ### Your contribution I could suggest a solution.

Description when the desc of arg in python docstring contains ":", the `_parse_python_function_docstring` will raise **ValueError: too many values to unpack (expected 2)**. A sample desc would be: """ Args: error_arg: this is an arg with an additional ":" symbol """ So, set `maxsplit` parameter to fix it.

### Feature request Amazon Bedrock now provides some useful metrics when it has finished: `"completion":"Response from Bedrock...","stop_reason":"stop_sequence","stop":"\n\nHuman:","amazon-bedrock-invocationMetrics":{"inputTokenCount":16,"outputTokenCount":337,"invocationLatency":4151,"firstByteLatency":136}}` It would be good to expose these via LangChain, similar to how OpenAI API provides them. ### Motivation To make it easier to calculate the cost of Amazon Bedrock queries. ### Your contribution I'm happy to test any solution. I'd look to existing developers to guide us how best to expose them.

I am currently operating a chroma docker on port 8001 and using it for my node js application with the URL CHROMA_URI=http://localhost:8001/, which allows me to read the vectors. However, when I try to use the same chroma_URI with langchain chroma, I encounter an error message. The error message reads: **{"lc":1,"type":"not_implemented","id":["langchain","vectorstores","chroma","Chroma"]}**. ![image](https://github.com/langchain-ai/langchain/assets/26340363/795dc113-a2ec-4a89-9da6-6dd75542d967) ![image](https://github.com/langchain-ai/langchain/assets/26340363/0cca4d46-2af0-4627-a2a1-0ea3713fd286) ![image](https://github.com/langchain-ai/langchain/assets/26340363/59715764-1abe-4493-be0e-0a18a37fc00a) The above screenshots are my codes. does anyone face this issue?

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!

### System Info - Python 3.9.13 - langchain==0.0.344 - langchain-core==0.0.8 ### Who can help? @agola11 @hwchase17 @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 - [X] Tools / Toolkits - [ ] Chains - [X] Callbacks/Tracing - [ ] Async ### Reproduction 1. Define a Custom Tool which useses some sort of OpenAI Model. For example GPT 3.5 2. Define a Tool agent which uses this Tool 3. Call the Agent inside a with Block with `get_openai_callback()` 4. The agent should now call the tool which uses an OpenAI Model 5. Calculate the Total Cost. By using the `get_openai_callback` variable. The cost does only include tokens used by the tool agent ### Expected behavior It should Include all Cost. Including the one from the tool

**Description** `embed_with_retry` is for sync operations and not for async operations. Use `async_embed_with_retry` for appropriate async operations. I'm using `OpenAIEmbedding(http_client=httpx.AsyncClient())` with only async operations. However, I got an error when I use `embedding.aembed_documents` because `embed_with_retry` uses sync OpenAI client with async http client.

### Issue with current documentation: The link to subscribe to the "newsletter" at the bottom of Community page (`/docs/docs/community.md`) is no longer available. ![image](https://github.com/langchain-ai/langchain/assets/4020306/66fdefef-af05-4397-8ecf-14e45043e061) As the image above indicates, the "form has moved to a new address", and the new address (https://form.typeform.com/to/KjZB1auB?typeform-source=6w1pwbss0py.typeform.com) gives "This typeform is now closed", as the image shown below: ![image](https://github.com/langchain-ai/langchain/assets/4020306/00c65a2c-89f8-4147-a8f5-2d2f47d11a54) ### Idea or request for content: If the newsletter is still operating, replace the current link with a new one where people can subscribe to it. If the newsletter is no longer running, replace the text with something else (eg. the link to langchain blogs).

<!-- Thank you for contributing to LangChain! Replace this entire comment with: - **Description:** a description of the change, - **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. --> Before, we need to use `params` to pass extra parameters: ```python from langchain.llms import Databricks Databricks(..., params={"temperature": 0.0}) ``` Now, we can directly specify extra params: ```python from langchain.llms import Databricks Databricks(..., temperature=0.0) ```

**Description:** This PR includes modifications to the `HuggingFacePipeline` class in the `langchain` library. Changes include the removal of unused imports, a minor cleanup in the code for better readability, and the addition of an `_astream` method for asynchronous streaming support. The `_astream` method integrates the `TextIteratorStreamer` from the `transformers` library and ensures inputs and the model are on the same device (cuda). Additionally, a print statement has been added in the generation loop for debugging purposes. **Issue:** N/A **Dependencies:** - `transformers` library **Tag maintainer:** @baskaryan, @eyurtsev, @hwchase17 for review.

### Feature request The `invoke()` method for RunnableWithFallbacks is only raising the first_error caught in the runnables. I would like to have an option to choose whether to raise the first error or last error. Can this be a parameter for `invoke()`? ### Motivation When using fallbacks, the first error could be related to the first Runnable. However, the error I'm actually interested to handle is the last error from the end of my fallbacks. The last error is the most downstream error from my chains, and it's the error I want to handle in my app business logic. ### Your contribution N/A

### Issue you'd like to raise. I am using ConversationalRetrievalChain. I have created two vector stores and I want the query from ConversationalRetrievalChain to be compared against both vector stores and results from both vector stores to be used to create the final answer. So I have decided to create two retrievers retriever1 = vectorstore1.as_retriever() retriever2 = vectorstore2.as_retriever() How can I now override the Retriever class so that when the query is compared against my custom_retriever, it is compared against documents from both retrievers, and documents from both retrievers are used to create the prompt. Note: i don't want to merge the vectorstores because that messes up the similarity search. ### Suggestion: _No response_

- **Description:** : As described in the issue below, https://python.langchain.com/docs/use_cases/summarization I've modified the Python code in the above notebook to perform well. I also modified the OpenAI LLM model to the latest version as shown below. `gpt-3.5-turbo-16k --> gpt-3.5-turbo-1106` This is because it seems to be a bit more responsive. - **Issue:** : #14066

### Issue you'd like to raise. Hello everyone, We are having request timeout on our calls and they are being getting retries after failing but we want to see how many times doing these retries and all their logs. When the requests are timing out, nothing has been sending callbackhandler and we want to see how many retries had been done under the ChatOpenAI LLM model. ### Suggestion: _No response_

It enables applications that: Are context-aware: connect a language model to sources of context (prompt instructions, few shot examples, content to ground its response in, etc.) Reason: rely on a language model to reason (about how to answer based on provided context, what actions to take, etc.) This framework consists of several parts. LangChain Libraries: The Python and JavaScript libraries. Contains interfaces and integrations for a myriad of components, a basic run time for combining these components into chains and agents, and off-the-shelf implementations of chains and agents. LangChain Templates: A collection of easily deployable reference architectures for a wide variety of tasks. LangServe: A library for deploying LangChain chains as a REST API. LangSmith: A developer platform that lets you debug, test, evaluate, and monitor chains built on any LLM framework and seamlessly integrates with LangChain. LangChain Diagram Together, these products simplify the entire application lifecycle: Develop: Write your applications in LangChain/LangChain.js. Hit the ground running using Templates for reference. Productionize: Use LangSmith to inspect, test and monitor your chains, so that you can constantly improve and deploy with confidence. Deploy: Turn any chain into an API with LangServe. LangChain Libraries The main value props of the LangChain packages are: Components: composable tools and integrations for working with language models. Components are modular and easy-to-use, whether you are using the rest of the LangChain framework or not Off-the-shelf chains: built-in assemblages of components for accomplishing higher-level tasks Off-the-shelf chains make it easy to get started. Components make it easy to customize existing chains and build new ones. Get started Here’s how to install LangChain, set up your environment, and start building. We recommend following our Quickstart guide to familiarize yourself with the framework by building your first LangChain application. Read up on our Security best practices to make sure you're developing safely with LangChain. NOTE These docs focus on the Python LangChain library. Head here for docs on the JavaScript LangChain library. LangChain Expression Language (LCEL) LCEL is a declarative way to compose chains. LCEL was designed from day 1 to support putting prototypes in production, with no code changes, from the simplest “prompt + LLM” chain to the most complex chains. Overview: LCEL and its benefits Interface: The standard interface for LCEL objects How-to: Key features of LCEL Cookbook: Example code for accomplishing common tasks Modules LangChain provides standard, extendable interfaces and integrations for the following modules: Model I/O Interface with language models Retrieval Interface with application-specific data Agents Let models choose which tools to use given high-level directives Examples, ecosystem, and resources Use cases Walkthroughs and techniques for common end-to-end use cases, like: Document question answering Chatbots Analyzing structured data and much more... Integrations LangChain is part of a rich ecosystem of tools that integrate with our framework and build on top of it. Check out our growing list of integrations. Guides Best practices for developing with LangChain. API reference Head to the reference section for full documentation of all classes and methods in the LangChain and LangChain Experimental Python packages. Developer's guide Check out the developer's guide for guidelines on contributing and help getting your dev environment set up. Community Head to the Community navigator to find places to ask questions, share feedback, meet other developers, and dream about the future of LLM’s. """ questions = qa_chain.run(context) print(questions) ``` output ``` [{'question': 'What are the main value props of the LangChain packages?', 'answer': 'The main value props of the LangChain packages are composable tools and integrations for working with language models, off-the-shelf chains for accomplishing higher-level tasks, and the ability to easily deploy chains as a REST API.'}] ``` ### Expected behavior I expect to specify the number of responses by setting the 'k' value.

The error is not reproduced when I use openai library AzureOpenAI . Also on openai the azure_ad_token_provider has type azure_ad_token_provider: 'AzureADTokenProvider | None' = None while in langchain it has type azure_ad_token_provider: Optional[str] = None which also makes me wonder if it would take as input a different type than string to work with. any ideas on how to fix this? Im actually using Azure Service principal authentication, and if I use as alternative field azure_ad_token = credential.get_token(“https://cognitiveservices.azure.com/.default”).token I get token expired after 60min which does not happen with a bearer token, so It is important to me to make the token_provider work. libraries : pydantic 1.10.12 pydantic_core 2.10.1 openai 1.2.0 langchain 0.0.342 langchain-core 0.0.7 ### Who can help? @hwchase17 @agola11 ### Information - [X] 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 import os from azure.identity import DefaultAzureCredential from azure.identity import get_bearer_token_provider from langchain.llms import AzureOpenAI from langchain.chat_models import AzureChatOpenAI credential = DefaultAzureCredential(interactive_browser_tenant_id=tenant_id, interactive_browser_client_id=client_id, client_secret=client_secret) token_provider = get_bearer_token_provider(credential, "https://cognitiveservices.azure.com/.default") endpoint = "https://xxxx.openai.azure.com" client = AzureOpenAI( azure_endpoint=endpoint, api_version="2023-05-15", azure_deployment="example-gpt-4", azure_ad_token_provider=token_provider) ### Expected behavior client = AzureOpenAI( azure_endpoint=endpoint, api_version="2023-05-15", azure_deployment="example-gpt-4", azure_ad_token_provider=token_provider) should return a Runnable instance which I can use for LLMChain

This PR adds chat model built around llamacpp llm, using some of the common facilities of chat models. **Issue:** Lack of chat model to use with llamacpp runtime. **Dependencies:** N/A

### Issue you'd like to raise. When using `langchain.chat_models` such as `ChatAnthropic` and `ChatOpenAI`, I am seeing a bunch of HTTP logs that look like the following: `2023-11-30 16:43:09 httpx INFO: HTTP Request: POST https://api.anthropic.com/v1/complete "HTTP[/1.1] 200 OK"` Any suggestions on how to disable them? ### Suggestion: _No response_

### Issue you'd like to raise. I've created a custom tool to query the equity daily quote, I would like to have two parameters in the tool function: stock_name and trade_date, and I would expect LLM Agent will automatically decide how many days quotes or which day's quote it should retrieve. ``` class SearchSchema(BaseModel): stock_name: str = Field(description="should be the name of the equity.") trade_date: str = Field(description="should be the trading date of the equity.") class DailyQuoteSearch(BaseTool): name = "equity daily quote search" description = "useful for equity daily quote retrieval" return_direct = False args_schema: Type[SearchSchema] = SearchSchema def _run(self, stock_name: str, trade_date: str) -> str: output = self.query_equity_daily_quote(stock_name, trade_date) return output ``` However, LLM doesn't seem to know how to pass in the trade date? Is it possible to have LLM think about the what trade_date should be passed? or I expect too much on agent intelligence? ``` pydantic_core._pydantic_core.ValidationError: 1 validation error for SearchSchema trade_date Field required [type=missing, input_value={'stock_name': 'xxxx'}, input_type=dict] ``` ### Suggestion: _No response_

### Description Starting from [openai version 1.0.0](https://github.com/openai/openai-python/tree/17ac6779958b2b74999c634c4ea4c7b74906027a#module-level-client), the camel case form of `openai.ChatCompletion` is no longer supported and has been changed to lowercase `openai.chat.completions`. In addition, the returned object only accepts attribute access instead of index access: ```python import openai # optional; defaults to `os.environ['OPENAI_API_KEY']` openai.api_key = '...' # all client options can be configured just like the `OpenAI` instantiation counterpart openai.base_url = "https://..." openai.default_headers = {"x-foo": "true"} completion = openai.chat.completions.create( model="gpt-4", messages=[ { "role": "user", "content": "How do I output all files in a directory using Python?", }, ], ) print(completion.choices[0].message.content) ``` So I implemented a compatible adapter that supports both attribute access and index access: ```python In [1]: from langchain.adapters import openai as lc_openai ...: messages = [{"role": "user", "content": "hi"}] In [2]: result = lc_openai.chat.completions.create( ...: messages=messages, model="gpt-3.5-turbo", temperature=0 ...: ) In [3]: result.choices[0].message Out[3]: {'role': 'assistant', 'content': 'Hello! How can I assist you today?'} In [4]: result["choices"][0]["message"] Out[4]: {'role': 'assistant', 'content': 'Hello! How can I assist you today?'} In [5]: result = await lc_openai.chat.completions.acreate( ...: messages=messages, model="gpt-3.5-turbo", temperature=0 ...: ) In [6]: result.choices[0].message Out[6]: {'role': 'assistant', 'content': 'Hello! How can I assist you today?'} In [7]: result["choices"][0]["message"] Out[7]: {'role': 'assistant', 'content': 'Hello! How can I assist you today?'} In [8]: for rs in lc_openai.chat.completions.create( ...: messages=messages, model="gpt-3.5-turbo", temperature=0, stream=True ...: ): ...: print(rs.choices[0].delta) ...: print(rs["choices"][0]["delta"]) ...: {'role': 'assistant', 'content': ''} {'role': 'assistant', 'content': ''} {'content': 'Hello'} {'content': 'Hello'} {'content': '!'} {'content': '!'} In [20]: async for rs in await lc_openai.chat.completions.acreate( ...: messages=messages, model="gpt-3.5-turbo", temperature=0, stream=True ...: ): ...: print(rs.choices[0].delta) ...: print(rs["choices"][0]["delta"]) ...: {'role': 'assistant', 'content': ''} {'role': 'assistant', 'content': ''} {'content': 'Hello'} {'content': 'Hello'} {'content': '!'} {'content': '!'} ... ``` ### Twitter handle [lin_bob57617](https://twitter.com/lin_bob57617)

### System Info I am using gpt-4 deployed on AzureOpenAI. I want to get the model used. From openai, I will get the model we used. But when I tried with langchain I got an older model. Basically, I am integrating with other services. So it is essential to get the model name intact for the cost calculations. What could be the issue with the langcahin? It works great with openai chat completion. ### Who can help? @hwchase17 @agola11 ### Information - [ ] The official example notebooks/scripts - [X] My own modified scripts ### Related Components - [ ] LLMs/Chat Models - [ ] Embedding Models - [X] Prompts / Prompt Templates / Prompt Selectors - [ ] Output Parsers - [ ] Document Loaders - [ ] Vector Stores / Retrievers - [ ] Memory - [ ] Agents / Agent Executors - [ ] Tools / Toolkits - [X] Chains - [ ] Callbacks/Tracing - [ ] Async ### Reproduction Steps to reproduce: ``` import os from openai import AzureOpenAI client = AzureOpenAI( azure_endpoint = "{}", api_key="{}", api_version="{}", azure_deployment="gpt4", ) response = client.chat.completions.create( model="gpt4", messages=[{"role": "user", "content": "tell me a joke"}] ) response.model ``` > 'gpt-4' ``` from langchain.schema import HumanMessage from langchain.chat_models.azure_openai import AzureChatOpenAI llm = AzureChatOpenAI( azure_endpoint = "{}", openai_api_key="{}", openai_api_version="{}", azure_deployment="gpt4", model_version="0613", temperature=0 ) response = llm.generate(messages=[[HumanMessage(content="tell me a joke")]]) response.llm_output["model_name"] ``` > 'gpt-3.5-turbo' ``` from langchain.chains import LLMChain from langchain.prompts import PromptTemplate prompt = PromptTemplate( input_variables=["joke"], template="Tell me a {joke}?", ) chain = LLMChain(llm=llm, prompt=prompt) response = chain.generate([{"joke":"joke"}]) response.llm_output["model_name"] ``` > 'gpt-3.5-turbo' ### Expected behavior From all we should be getting gpt-4 as I have deployed only got-4 on azure openai

- **Description:** fix `import` issue for `mongodb atlas` vectore store integration - **Issue:** none - **Dependencies:** none while trying to follow official `langchain`'s [mongodb integration guide](https://python.langchain.com/docs/integrations/vectorstores/mongodb_atlas), an import error will happen. It's caused by incorrect import location: - `from pymongo import DriverInfo` should be `from pymongo.driver_info import DriverInfo` - reference: [pymongo's DriverInfo class](https://pymongo.readthedocs.io/en/stable/api/pymongo/driver_info.html#pymongo.driver_info.DriverInfo) Thanks!

Description: Video imagery to text (Closed Captioning) This pull request introduces the VideoCaptioningChain, a tool for automated video captioning. It processes audio and video to generate subtitles and closed captions, merging them into a single SRT output. Issue: https://github.com/langchain-ai/langchain/issues/11770 Dependencies: opencv-python, ffmpeg-python, assemblyai, transformers, pillow, torch, openai Tag maintainer: @baskaryan @hwchase17 Hello!

We are a group of students from the University of Toronto (@LunarECL, @TomSadan, @nicoledroi1, @A2113S) that want to make a contribution to the LangChain community! We have ran make format, make lint and make test locally before submitting the PR. To our knowledge, our changes do not introduce any new errors. Thank you for taking the time to review our PR!

Another use is for scientific observation, as in a Mössbauer spectrometer. The most common type is a radioisotope thermoelectric generator, which has been used on many space probes and on crewed lunar missions. Small fission reactors for Earth observation satellites, such as the TOPAZ nuclear reactor, have also been flown.[1] A radioisotope heater unit is powered by radioactive decay and can keep components from becoming too cold to function, potentially over a span of decades.[2] The United States tested the SNAP-10A nuclear reactor in space for 43 days in 1965,[3] with the next test of a nuclear reactor power system intended for space use occurring on 13 September 2012 with the Demonstration Using Flattop Fission (DUFF) test of the Kilopower reactor.[4] After a ground-based test of the experimental 1965 Romashka reactor, which used uranium and direct thermoelectric conversion to electricity,[5] the USSR sent about 40 nuclear-electric satellites into space, mostly powered by the BES-5 reactor. The more powerful TOPAZ-II reactor produced 10 kilowatts of electricity.[3] Examples of concepts that use nuclear power for space propulsion systems include the nuclear electric rocket (nuclear powered ion thruster(s)), the radioisotope rocket, and radioisotope electric propulsion (REP).[6] One of the more explored concepts is the nuclear thermal rocket, which was ground tested in the NERVA program. Nuclear pulse propulsion was the subject of Project Orion.[7] """ docs = [ Document( page_content=split, metadata={"source": "https://en.wikipedia.org/wiki/Nuclear_power_in_space"}, ) for split in text.split("\n\n") ] ``` When I attach a callback that prints the [inputs](https://github.com/langchain-ai/langchain/blob/00a6e8962cc778cd8f6268cefc304465598c02cf/libs/core/langchain_core/callbacks/base.py#L197) in `on_chain_start`, even if every sub-chain only uses one Document, the `inputs` is always the full Document list. ### Expected behavior I expect the `inputs` in `on_chain_start` only includes the inputs that are used by this chain, not always the full list, otherwise it's totally meaningless to duplicate the same inputs many times.

### Issue with current documentation: The current [section on Amazon OpenSearch Serverless][1] (AOSS) vector store uses the `AWS4Auth` class to authenticate to AOSS, yet the official [OpenSearch documentation][2] suggests using the `AWS4SignerAuth` class instead. Using the latter does currently **not** work with LangChain due to how AOSS is detected when the class is instantiated (c.f. #14129 ) Further, the notebook lacks information on where to import the `AWS4Auth` class from and how to configure it with different AWS credentials (static access key/secret key, temporary credentials, etc.). It also lacks references on how to configure access policies (IAM, AOSS data access policies, etc.) [1]: https://github.com/langchain-ai/langchain/blob/master/docs/docs/integrations/vectorstores/opensearch.ipynb [2]: https://opensearch.org/docs/latest/clients/python-low-level/#connecting-to-amazon-opensearch-serverless ### Idea or request for content: Add installation instructions for the [requests_aws4auth][1] package and links to its [Github repo][2] in order to showcase configuration with different AWS credentials. Additionally reference [AWS documentation for AOSS][3] in order to get started [setting up permissions][4] [1]: https://pypi.org/project/requests-aws4auth/ [2]: https://github.com/tedder/requests-aws4auth#basic-usage [3]: https://docs.aws.amazon.com/opensearch-service/latest/developerguide/serverless-getting-started.html [4]: https://docs.aws.amazon.com/opensearch-service/latest/developerguide/serverless-data-access.html

### Issue you'd like to raise. I only see `metadata` as parameter for few callback handler methods, but I would like to have access to metadata in other methods such as `on_chain_error()` and `on_llm_error()`. Currently, I can only see the `tags` in these methods. I have error handling in my callback handler using `on_chain_error()` and I'd like to add information in my metadata dictionary to my exceptions (such as LLM name, model, things related to my chain, etc...). I can put a list of tags, but I'd much prefer to use a dictionary to get certain keys and have my exceptions instantiated properly. ### Suggestion: Please make both tags and metadata available for all callback handler methods.

### Feature request I notice the other functions, such as add_texts and add_embeddings allow you to pass a unique list of IDs that can get paired with your embedding. There is no such parameter for the add_documents function. This means when you delete a document and add an updated version of it using add_documents, its unique ID won't be added to the vector store. ### Motivation Inability to add unique ID to document after calling the add_documents function from FAISS ### Your contribution Not sure as far as I know. If I can, let me know what you need from me.

### Issue you'd like to raise. I want to integrate ConversationalRetrievalChain with history into Gradio app. For now I have the following approach: ``` # Memory buffer memory = ConversationBufferWindowMemory(k=2,memory_key="chat_history", return_messages=True) # LLM chain chain = ConversationalRetrievalChain.from_llm(llm=llm, chain_type='stuff', retriever=vector_store.as_retriever( search_kwargs={"k": 2}), memory=memory) with gr.Blocks() as demo: gr.Markdown("# SageMaker Docs Chat 🤗") gr.Markdown("### Ask me question about Amazon SageMaker!") chatbot = gr.Chatbot(label="Chat history") message = gr.Textbox(label="Ask me a question!") clear = gr.Button("Clear") def user(user_message, chat_history): return gr.update(value="", interactive=False), chat_history + [[user_message, None]] def bot(chat_history): user_message = chat_history[-1][0] llm_response = qa({"question": user_message}) bot_message = llm_response["answer"] chat_history[-1][1] = "" for character in bot_message: chat_history[-1][1] += character time.sleep(0.005) yield chat_history response = message.submit(user, [message, chatbot], [message, chatbot], queue=False).then( bot, chatbot, chatbot ) response.then(lambda: gr.update(interactive=True), None, [message], queue=False) demo.queue() demo.launch() ``` which works fine for the simple question answer without history. I tried to implement something similar to this guide (https://github.com/facebookresearch/llama-recipes/blob/main/demo_apps/Llama2_Gradio.ipynb), but failed to do so. Do you have any solution for this use-case or any specific guide? ### Suggestion: _No response_

### System Info langchain==0.0.330, python 3.9 ### Who can help? @hwchase17 @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 - [X] Agents / Agent Executors - [ ] Tools / Toolkits - [X] Chains - [ ] Callbacks/Tracing - [ ] Async ### Reproduction I created an agent as follows: ``` def batch_embedding(node_label:str, text_node_properties:list): vector_index = Neo4jVector.from_existing_graph( OpenAIEmbeddings(), url=URL_DB_GRAPH, username=USERNAME, password=PASSWORD, index_name= node_label, node_label= node_label, text_node_properties=text_node_properties, embedding_node_property='embedding', ) return vector_index ``` model_name= "gpt-4" llm= ChatOpenAI(temperature=0, model_name=model_name) vector_index = batch_embedding("Alarms", ["solution", "description", "type"]) vector_qa = RetrievalQA.from_chain_type( llm=llm, chain_type="stuff", retriever=vector_index.as_retriever()) ``` cypher_chain = GraphCypherQAChain.from_llm( cypher_llm = llm, qa_llm = ChatOpenAI(temperature=0), graph=graph, verbose=True, cypher_prompt=CYPHER_GENERATION_PROMPT ) ``` tools = [ Tool( name="Alarms", func=vector_qa.run, description=prompt_per_alarms, ), Tool( name="Graph", func=cypher_chain.run, description=prompt_per_Graph, ), ] mrkl = initialize_agent( tools, ChatOpenAI(temperature=0, model_name=model_name), agent=AgentType.OPENAI_FUNCTIONS, verbose=True, memory=memory ) message = request.form['message'] response = mrkl.run(message) When I receive an answer from cypher_chain.run I can see that I've a full context with an output but the finished chain says "I'm sorry, but I don't have the information.." (see the image attached) ![example](https://github.com/langchain-ai/langchain/assets/119319987/5d2e7308-e944-4c32-b2ad-9dd8643ef905) . I noticed that this issue come back when I have a full context with an array of data. ### Expected behavior Finished chain contains the full context and write the answer.

### Issue you'd like to raise. I am currently piecing together some of the tutorials on the langchain documentation page to use a CustomOutputParser and a CustomPrompt Template similar to the ZeroShotReact Template. While parsing the actions, I have a scenario where, the model returns Action as None & Action Input as None. In that case, I would like access to the dynamically created prompt with in the CustomOutputParser to call another LLM and return the action as call to another LLM to complete the action. **Current Approach:** ```python # Set up a prompt template class CustomPromptTemplatePirate(StringPromptTemplate): # The template to use template: str # The list of tools available tools: List[Tool] def format(self, **kwargs) -> str: # Get the intermediate steps (AgentAction, Observation tuples) # Format them in a particular way intermediate_steps = kwargs.pop("intermediate_steps") thoughts = "" for action, observation in intermediate_steps: thoughts += action.log thoughts += f"\nObservation: {observation}\nThought: " # Set the agent_scratchpad variable to that value kwargs["agent_scratchpad"] = thoughts # Create a tools variable from the list of tools provided kwargs["tools"] = "\n".join([f"{tool.name}: {tool.description}" for tool in self.tools]) # Create a list of tool names for the tools provided kwargs["tool_names"] = ", ".join([tool.name for tool in self.tools]) return self.template.format(**kwargs) class CustomOutputParserPirate(AgentOutputParser): def parse(self, llm_output: str) -> Union[AgentAction, AgentFinish]: # Check if agent should finish if "Final Answer:" in llm_output: return AgentFinish( # Return values is generally always a dictionary with a single `output` key # It is not recommended to try anything else at the moment :) return_values={"output": llm_output.split("Final Answer:")[-1].strip()}, log=llm_output, ) # Parse out the action and action input regex = r"Action\s*\d*\s*:(.*?)\nAction\s*\d*\s*Input\s*\d*\s*:[\s]*(.*)" match = re.search(regex, llm_output, re.DOTALL) if not match: raise OutputParserException(f"Could not parse LLM output: `{llm_output}`") action = match.group(1).strip() action_input = match.group(2) # Return the action and action input return AgentAction(tool=action, tool_input=action_input.strip(" ").strip('"'), log=llm_output) # Set up the base template template = """Complete the objective as best you can. You have access to the following tools: {tools} Use the following format: Question: the input question you must answer Thought: you should always think about what to do Action: the action to take, should be one of [{tool_names}] Action Input: the input to the action Observation: the result of the action ... (this Thought/Action/Action Input/Observation can repeat N times) Thought: I now know the final answer Final Answer: the final answer to the original input question These were previous tasks you completed: Begin! Question: {input} {agent_scratchpad}""" search = SerpAPIWrapper() tools= [Tool( name="Search", func=search.run, description="useful for when you need to answer questions about current events", )] prompt = CustomPromptTemplatePirate( template=template, tools=tools, # This omits the `agent_scratchpad`, `tools`, and `tool_names` variables because those are generated dynamically # This includes the `intermediate_steps` variable because that is needed input_variables=["input", "intermediate_steps"] ) output_parser = CustomOutputParserPirate() # LLM chain consisting of the LLM and a prompt llm_chain = LLMChain(llm=llm, prompt=prompt) tool_names = [tool.name for tool in tools] agent = LLMSingleActionAgent( llm_chain=llm_chain, output_parser=output_parser, stop=["\nObservation:"], allowed_tools=tool_names ) agent_executor = AgentExecutor.from_agent_and_tools(agent=agent, tools=tools, verbose=True) agent_executor.run("How many people live in canada as of 2023?") ``` **Challenges Faced:** I am unable to figure out how to access the callback or any other similar approach to use the complete Prompt/User Input with in the context of the CustomOutputParser **Desired Outcome:** ```python def parse(self, llm_output: str, prompt:start) -> Union[AgentAction, AgentFinish]: # Check if agent should finish ..... if not 'Action' & not 'Action Input' : call AgentAction with another llm fine_tuned defined as tool with the user question as input ex: Write a summary on Canada. I need a way to access the user question here. ``` I would greatly appreciate any advice, documentation, or examples that could assist me in accomplishing this task. Thank you very much for your time and support. ### Suggestion: _No response_

### System Info Python 3.10 Langchain 0.0.311 ### 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 - [X] Vector Stores / Retrievers - [ ] Memory - [ ] Agents / Agent Executors - [ ] Tools / Toolkits - [ ] Chains - [ ] Callbacks/Tracing - [ ] Async ### Reproduction ```python from langchain.text_splitter import RecursiveCharacterTextSplitter url = "https://plato.stanford.edu/entries/goedel/" headers_to_split_on = [ ("h1", "Header 1"), ("h2", "Header 2"), ("h3", "Header 3"), ("h4", "Header 4"), ] html_splitter = HTMLHeaderTextSplitter(headers_to_split_on=headers_to_split_on) # for local file use html_splitter.split_text_from_file(<path_to_file>) html_header_splits = html_splitter.split_text_from_url(url) chunk_size = 500 chunk_overlap = 30 text_splitter = RecursiveCharacterTextSplitter( chunk_size=chunk_size, chunk_overlap=chunk_overlap ) # Split splits = text_splitter.split_documents(html_header_splits) splits[80:85] ``` [Reference](https://python.langchain.com/docs/modules/data_connection/document_transformers/text_splitters/HTML_header_metadata#2-pipelined-to-another-splitter-with-html-loaded-from-a-web-url) The bug seems to be in [etree](https://github.com/langchain-ai/langchain/blob/master/libs/langchain/langchain/text_splitter.py#L586). A simple fix is perhaps like below: ```python from lxml import etree from pathlib import Path path = Path(".../langchain/document_transformers/xsl/html_chunks_with_headers.xslt") # etree.parse(path) Throws etree.parse(str(path)) ``` ### Expected behavior The code in the reproducer should work.

### Issue you'd like to raise. I use the below code to load data and splitted it and embedded it and finally pushing it into vector store. during that process, I'm getting **openai.NotFoundError: Error code: 404 - {'error': {'code': '404', 'message': 'Resource not found'}}**. After this method failed, I also tried with AzurecosmosDBVectorsearch vector store it also failed and returned the same error. Kindly help on this. ``` from langchain.embeddings.azure_openai import AzureOpenAIEmbeddings from langchain.vectorstores.azure_cosmos_db import AzureCosmosDBVectorSearch from langchain.vectorstores.chroma import Chroma from langchain.text_splitter import RecursiveCharacterTextSplitter from langchain.document_loaders import PyPDFLoader # Load PDF loaders = [ PyPDFLoader("ai.pdf") ] docs = [] for loader in loaders: docs.extend(loader.load()) # Define the Text Splitter text_splitter = RecursiveCharacterTextSplitter( chunk_size=1500, chunk_overlap=150 ) # Create a split of the document using the text splitter res_splits = text_splitter.split_documents(docs) embedding = AzureOpenAIEmbeddings( openai_api_version="1699-02-30", openai_api_key="xxxxxxxxxxxxxxxxxxxxxxxxx", # model_name="gpt-35-turbo", azure_endpoint="https://ggggggggggggggggggggggg.openai.azure.com/") persist_directory = 'docs/chroma/' # Create the vector store vectordb = Chroma.from_documents( documents=res_splits, embedding=embedding, persist_directory=persist_directory ) print(vectordb._collection.count()) ``` ### Suggestion: _No response_

- **Description:** The class allows to only select between a few predefined prompts from the paper. That is not ideal, since other use cases might need a custom prompt. The changes made allow for this. To be able to monitor those, I also added functionality to supply a custom run_manager. - **Issue:** no issue, but a new feature, - **Dependencies:** none, - **Tag maintainer:** @hwchase17, - **Twitter handle:** @yvesloy
