### Issue with current documentation: I cannot handle my custom_tool's raised errors. I have this weatherTool: ``` class GetCurrentWeatherTool(BaseTool): name = "get_current_weather" description = "Get the current weather for a specified location" args_schema: Type[WeatherInput] = WeatherInput def _run( self, location: str, run_manager: Optional[CallbackManagerForToolRun] = None ) -> str: """Use the tool.""" return get_current_weather(location) async def _arun( self, location: str, run_manager: Optional[AsyncCallbackManagerForToolRun] = None ) -> str: """Use the tool asynchronously.""" # You can implement the async version of the method here or raise a NotImplementedError if async is not supported raise NotImplementedError("get_current_weather does not support async") def _handle_error(error: ToolException) -> str: return ( "The following errors occurred during tool execution:" + error.args[0] + "Location couldn't be found, please try another tool." ) ``` And I raise ToolException when the API call gets an error: `raise ToolException("location has been found.")` inside of `get_current_weather` Now I am adding this tool to my tools when I'm creating my agent: ``` self.weather = GetCurrentWeatherTool() Tool( name="Weather", func=self.weather.run, description="useful for weather related questions", return_direct=True, ) ``` In the documentation [Custom Tools](https://python.langchain.com/docs/modules/agents/tools/custom_tools#handling-tool-errors) it explains how to add it and gives an example: ``` Tool.from_function( func=search_tool1, name="Search_tool1", description=description, handle_tool_error=True, ), ``` However I couldnt find the equal of that for Subclassing the BaseTool. ### Idea or request for content: It would be great to give an example for Subclassed CustomTool(BaseTool) when defining the tools.

### Feature request The current MRKL `FORMAT_INSTRUCTIONS` prompt ([here](https://github.com/langchain-ai/langchain/blob/master/libs/langchain/langchain/agents/mrkl/prompt.py)) looks like this: ``` python FORMAT_INSTRUCTIONS = """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""" ``` Which is not very good- the similar tool selection prompts in other agents are MUCH better, and contain detailed formatting instructions. This prompt should be brought in line with the likes of the [Structured Chat Prompt](https://github.com/langchain-ai/langchain/blob/master/libs/langchain/langchain/agents/structured_chat/prompt.py) which is much better, in a number of ways (clearer instructions, better formatting, etc.) As always, I appreciate your hard work! ### Motivation The motivation for this is to bring the prompt quality up throughout the project. Overall, there is probably some refactoring that could be done in this area to make it easier to centralize how prompts are used... I know that there's the hub now, but I am not sure if that fits this bill. ### Your contribution I will try to contribute to this, but my workload is intense, and I don't have time currently... however, I have a number of things that I have modified in my own instance that I really should contribute back. 🥲

This PR addresses the limitation of Azure OpenAI embeddings, which can handle at maximum 16 texts in a batch. This can be solved setting `chunk_size=16`. However, I'd love to have this automated, not to force the user to figure where the issue comes from and how to solve it. Closes #4575. @baskaryan

- **Description:** modified the method a `from_texts` as the` **kwargs` was wrongly set to the self initialization. This produced errors when additional optional parameters were added. Also, they weren't passed to the subsequent add_text method which causes not being able to add optional parameters to reach `pymilvus`. Now you can add any additional parameters like `partition_name` which would make effective inserting in partitions. - **Issue:** [#10671](https://github.com/langchain-ai/langchain/issues/10671) - **Dependencies:** N/A - **Tag maintainer:** @hwchase17

### Issue you'd like to raise. Hi , I want to know how it would be possible to filter with the Sitemap Loader updated pages of 2023 from a website. I do not want to get all the website but only 2023 updated pages. Here is my code: `# fixes a bug with asyncio and jupyter import nest_asyncio nest_asyncio.apply() from langchain.document_loaders.sitemap import SitemapLoader loader = SitemapLoader( "", filter_urls=[""] ) docs = loader.load()` How can it be possible in it please? Thank you, ### Suggestion: _No response_

I know the intermediate steps can get the list of list of action and observation tuples. If I use the Aiplugin tool to create the api call. Can I get the detail of request and response that agent make? I want to know what request and response that agent make for debugging, because agent not work correctly often.

Hi, i stumbled over this error because i didn't read the docs after i updated my version so i thought maybe for the next person that doesn't read the docs. Description: Check if the parameters `compress to size` and `normalize` are set because if you do not define these in the AlephAlphaAsymmetricSemanticEmbedding explicit it fails with this error: `ValueError: (400, '{"error":"Json deserialize error: invalid type: null, expected a boolean at line 1 column 2378","code":"PAYLOAD_ERROR"}') `This seems hard to figure out therefore the friendly error message :) Dependencies: None Tag maintainer: @hwchase17. It may be a good idea to write a test for aleph alpha embeddings in the future because i did not find one yet, the only question remains is if you have a token for aleph alpha in your ci that one can use? Then i would offer to write one if that helps.

### Issue with current documentation: The parameters listed in the [DallEAPIWrapper documentation](https://api.python.langchain.com/en/latest/utilities/langchain.utilities.dalle_image_generator.DallEAPIWrapper.html) are incorrect for: - n - open_api_key - size ### Idea or request for content: See [OpenAI API reference](https://platform.openai.com/docs/api-reference/images/create) for the correct parameter definitions

### Feature request The [`openai.Image.create()` endpoint](https://platform.openai.com/docs/api-reference/images/create) has an `n` parameter that allows you to generate 1-10 images. However, I used the looked at the langchain `DallEAPIWrapper()` and only got one image URL. After looking at its [source code](https://github.com/langchain-ai/langchain/blob/master/libs/langchain/langchain/utilities/dalle_image_generator.py), I see that the langchain `DallEAPIWrapper()` only returns the first image URL. This should be to easy to fix. ### Motivation It would be great to be able to generate multiple images from a single input and API call. ### Your contribution I can submit a pull request to modify `def _dalle_image_url` method to return all image URLs.

I only add this part: ``` # Ensure the final answer doesn't exceed 160 characters if len(final_answer) > 160: final_answer = final_answer[:157] + '...' 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": final_answer}, log=llm_output, ) ``` To ensure that the output is 160 char however somehow it affects the output and the system throws an error on the outputparser like this: ``` chain/error] [1:chain:AgentExecutor] [4.40s] Chain run errored with error: "OutputParserException('Could not parse LLM output: `I found the closing price of Nvidia stock: $455.72 on 09/08/2023.

Question 2: I would like to wrap my output parser with something like https://python.langchain.com/docs/modules/model_io/output_parsers/retry so If it fails to parse the output it should come to an llmchain and that llmchain's only job should be parsing correctly OR if there is no answer giving the correct output as "I couldnt find the answer for {x}" etc. ### Expected behavior I was expecting to truncating the final_answer only will have an effect on the output's character count however it does affect the whole system. How can I connect the outputParsers?

### Issue you'd like to raise. Hey, I am trying to follow various approaches online to create a simple chat interface in streamlit to chat with your pandas dataframe. I always face the issue, that I cant extract the full description of the steps. One example is the following code: ``` from langchain.agents import AgentType from langchain.agents import create_pandas_dataframe_agent from langchain.callbacks import StreamlitCallbackHandler from langchain.chat_models import AzureChatOpenAI if prompt := st.chat_input(placeholder = " "): st.session_state.messages.append({"role": "user", "content": prompt}) st.chat_message("user").write(prompt) llm = AzureChatOpenAI() pandas_df_agent = create_pandas_dataframe_agent(llm,df,verbose=True,agent_type=AgentType.OPENAI_FUNCTIONS,handle_parsing_errors=True) with st.chat_message("assistant"): st_cb = StreamlitCallbackHandler(st.container(), expand_new_thoughts=False) response = pandas_df_agent.run(st.session_state.messages, callbacks=[st_cb]) st.session_state.messages.append({"role": "assistant", "content": response}) st.write(response) ``` However if the steps executed are too long it truncates the message as seen below? ![image](https://github.com/langchain-ai/langchain/assets/141514724/066dd5d2-1c32-4d30-b015-b39705706dba) Anyone who knows how to fix this, or have seen a solution where its no the case? ### Suggestion: I assume its something to do with the StreamlitCallbackHandler, outputting to the st.container. Maybe I need to change the properties of that container or the settings in StreamlitCallbackHandler?

### System Info python==3.8 langchain==217 ### Who can help? _No response_ ### Information - [X] The official example notebooks/scripts - [ ] My own modified scripts ### Related Components - [ ] LLMs/Chat Models - [ ] Embedding Models - [X] Prompts / Prompt Templates / Prompt Selectors - [X] Output Parsers - [ ] Document Loaders - [ ] Vector Stores / Retrievers - [ ] Memory - [X] Agents / Agent Executors - [X] Tools / Toolkits - [X] Chains - [ ] Callbacks/Tracing - [ ] Async ### Reproduction I'm testing one of the tools that is being used in the zero shot agent, which is making an external api call and get json response. I'm trying to use LLMRequestsChain, and this chain needs an input as dictionary with query and url keys to make a call. `inputs = { "query": user_message, "url": f"{endpoint}/user/{mxUser}/accounts?page=1&records_per_page=10" } result = agent_chain.zero_shot_agent_chain().run({"question": inputs}) ` Once the dict has been passed to the tool which is the LLMRequestsChain, It throws InvalidSchema exception saying `No connection adapters were found for '{\n "query": "what\'s my balance?",\n "url": "targeted url"\n}'` ### Expected behavior looks like the dict has been passed to the tool as a string. Is there any workaround or any idea to work with?

### Issue with current documentation: Here is the documentation that I'm talking: https://python.langchain.com/docs/modules/agents/how_to/custom_llm_agent The problem with is that its not returning the actual final answer but the observation. Normally it should return this as written: ``` > Entering new AgentExecutor chain... Thought: I need to find out the population of Canada in 2023 Action: Search Action Input: Population of Canada in 2023 Observation:The current population of Canada is 38,658,314 as of Wednesday, April 12, 2023, based on Worldometer elaboration of the latest United Nations data. I now know the final answer Final Answer: Arrr, there be 38,658,314 people livin' in Canada as of 2023! > Finished chain. "Arrr, there be 38,658,314 people livin' in Canada as of 2023!" ``` But stucks here: ``` > Entering new AgentExecutor chain... Thought: I need to search for the current population of Canada. Action: Search Action Input: "current population of Canada 2023" Observation:38,781,291 people ``` It should be related to the output parser: ``` class CustomOutputParser(AgentOutputParser): def parse(self, llm_output: str) -> Union[AgentAction, AgentFinish]: # Check if agent should finish if "Observation:" in llm_output: # Parse the observation value observation_value = llm_output.split("Observation:")[-1].strip() # Construct a final answer based on the observation final_answer = f"Arrr, there be {observation_value} people livin' in Canada as of 2023!" # Create a log with the final answer final_log = llm_output + f"\nThought: I now know the final answer\nFinal Answer: {final_answer}" return AgentFinish( return_values={"output": final_answer}, log=final_log, ) # 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) output_parser = CustomOutputParser() ``` How to change that ``` # Construct a final answer based on the observation final_answer = f"Arrr, there be {observation_value} people livin' in Canada as of 2023!" ``` So it can call one last time the LLMChain to sumarize the answer for us? ### Idea or request for content: It would be great to update the Custom LLM Agent Tutorial.

- **Description:** This pull request introduces the Portkey integration to the Langchain repository, enhancing its production capabilities. Portkey offers a comprehensive set of tools and features to optimize the performance and reliability of AI applications. #### Key Features of Portkey's Integration with Langchain: 1. **🚪 AI Gateway**: - **Automated Fallbacks & Retries**: Ensure your application remains functional even if a primary service fails. - **Load Balancing**: Efficiently distribute incoming requests among multiple models. - **Semantic Caching**: Reduce costs and latency by intelligently caching results. 2. **🔬 Observability**: - **Logging**: Keep track of all requests for monitoring and debugging. - **Requests Tracing**: Understand the journey of each request for optimization. - **Custom Tags**: Segment and categorize requests for better insights. 3. **📝 Continuous Improvement with User Feedback**: - **Feedback Collection**: Seamlessly gather feedback on any served request, be it on a generation or conversation level. - **Weighted Feedback**: Obtain nuanced information by attaching weights to user feedback values. - **Feedback Metadata**: Incorporate custom metadata with the feedback to provide context, allowing for richer insights and analyses. 4. **🔑 Secure Key Management**: - **Virtual Keys**: Portkey transforms original provider keys into virtual keys, ensuring your primary credentials remain untouched. - **Multiple Identifiers**: Ability to add multiple keys for the same provider or the same key under different names for easy identification without compromising security. - **Issue:** the issue # it fixes (if applicable), - **Dependencies:** This integration incorporates an external library named `portkey-ai`, which can be easily installed via pip. `portkey-ai` plays a crucial role in the seamless operation of Portkey Integration and is an essential component of its internal processes. - **Tag maintainer:** @baskaryan, - **Twitter handle:** [PortkeyAI](https://x.com/PortkeyAI?s=20) - **Additional Notes:** We have conducted a cleanup process by removing obsolete notebooks and files that are no longer relevant following the integration changes.

### System Info The code snipped will execute. However, when changing the chunk size down, executing again, and then changing the chunk size up again, the chunk size will stay on the low value. It seems that the chunk size is sometimes saved, even though the objects get ge-instantiated. I ran the code snipped in a colab file. versions: chromadb-0.4.10-py3-none-any.whl langchain-0.0.291-py3-none-any.whl ### 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 - [X] Vector Stores / Retrievers - [ ] Memory - [ ] Agents / Agent Executors - [ ] Tools / Toolkits - [ ] Chains - [ ] Callbacks/Tracing - [ ] Async ### Reproduction ``` from langchain.text_splitter import RecursiveCharacterTextSplitter from langchain.embeddings import OpenAIEmbeddings from langchain.vectorstores import Chroma doc = Document(page_content=pdf_texts[0][1], metadata={}) def storeDocument(doc): text_splitter4 = RecursiveCharacterTextSplitter(chunk_size = 400, chunk_overlap = 5) all_splits4 = text_splitter4.split_documents([doc]) vectorStore = Chroma.from_documents(documents=all_splits4, embedding=OpenAIEmbeddings(openai_api_key="...")) return vectorStore storeDocument(doc).similarity_search_with_score("Where is the fund's geographic location?",k=10) ``` ### Expected behavior I would expect the chunk size to change the output of similarity matching.

### Feature request When calling from_documents directly from vectorstore I do this: ``` vector_db = Milvus.from_documents( docs, embeddings, connection_args={ "host": config.MILVUS_HOST, "port": config.MILVUS_PORT, }, collection_name = collection_name, ) ``` This argument is not accepted: `partition_name = 'tes'` If you deep dive inside the `from_documents` to `from_text` in `milvus.py` you notice that uses `add_texts` method, which also is not accepting `partition_name`. This uses the `add_texts` uses `collection.py` - insert from pymilvus orm that does accept `partition_name` as an optional argument: ``` def insert( self, data: Union[List, pd.DataFrame, Dict], partition_name: Optional[str] = None, timeout: Optional[float] = None, **kwargs, ) -> MutationResult:` `` ### Motivation Having a way of inserting directly in a partition from langchain to Milvus ### Your contribution To add the "partition_name" attribute as optional in the from_documents somehow

### Issue you'd like to raise. The effect of tools with return_direct=False for CHAT_CONVERSATIONAL_REACT_AGENT only causes the LLM to generate a final answer based on tool observation, but never in another tool invocation. The same is not happening with CONVERSATIONAL_REACT_AGENT which seems able to generate new tool queries after the first one. Is this a feature that can be fixed simply acting on the agent policy prompt, or is there a better way to enable such feature? Thank you very much. ### Suggestion: _No response_

**Description:** Renamed argument `database` in `SQLDatabaseSequentialChain.from_llm()` to `db`, I realize it's tiny and a bit of a nitpick but for consistency with SQLDatabaseChain (and all the others actually) I thought it should be renamed. Also got me while working and using it today. :heavy_check_mark: Please make sure your PR is passing linting and testing before submitting. Run `make format`, `make lint` and `make test` to check this locally.

This PR is a documentation fix. Description: * fixes imports in the code samples in the docstrings of `create_openai_fn_chain` and `create_structured_output_chain` * fixes imports in `docs/extras/modules/chains/how_to/openai_functions.ipynb` * removes unused imports from the notebook Issues: * the docstrings use `from pydantic_v1 import BaseModel, Field` which this PR changes to `from langchain.pydantic_v1 import BaseModel, Field` * importing `pydantic` instead of `langchain.pydantic_v1` leads to errors later in the notebook

It lives in `docs/extras` directory. If no one reviews your PR within a few days, please @-mention one of @baskaryan, @eyurtsev, @hwchase17. --> **Description** It is for #10423 that it will be a useful feature if we can extract images from pdf and recognize text on them. I have implemented it with `PyPDFLoader`, `PyPDFium2Loader`, `PyPDFDirectoryLoader`, `PyMuPDFLoader`, `PDFMinerLoader`, and `PDFPlumberLoader`. [RapidOCR](https://github.com/RapidAI/RapidOCR.git) is used to recognize text on extracted images. It is time-consuming for ocr so a boolen parameter `extract_images` is set to control whether to extract and recognize. I have tested the time usage for each parser on my own laptop thinkbook 14+ with AMD R7-6800H by unit test and the result is: | extract_images | PyPDFParser | PDFMinerParser | PyMuPDFParser | PyPDFium2Parser | PDFPlumberParser | | ------------- | ------------- | ------------- | ------------- | ------------- | ------------- | | False | 0.27s | 0.39s | 0.06s | 0.08s | 1.01s | | True | 17.01s | 20.67s | 20.32s | 19,75s | 20.55s | **Issue** #10423 **Dependencies** rapidocr_onnxruntime in [RapidOCR](https://github.com/RapidAI/RapidOCR/tree/main)

### System Info langchain==0.0.287, MACOS ### Who can help? **TLDR: Where are the tools in prompts ?** Hi everyone, I am experimenting with the AgentTypes and I found its not showing everything in the prompts. My langchain.debug =True and I am expecting to see every detail about my prompts. However when I use `agent=AgentType.OPENAI_FUNCTIONS` I dont actually see the full prompt that is given to the OpenAI. Agent Configurations: ``` # There is only one tool. tools = [ Tool( name="Search", func=search.run, description="useful for when you need to search internet for question. You should ask targeted questions" )] # Initialize the agent llm = ChatOpenAI(temperature=0, model="gpt-3.5-turbo-0613", openai_api_key=os.getenv("OPENAPI_SECRET_KEY")) # The systemMessage is simple system_message = SystemMessage( content="Your name is BOTIFY and try to answer the question, you can use the tools.") agent_kwargs = { "system_message": system_message, } agent = initialize_agent(tools, llm, agent=AgentType.OPENAI_FUNCTIONS, agent_kwargs=agent_kwargs, verbose=True) ``` Example 1: ``` response = agent.run("whats the lyrics of Ezhel Pofuduk") ``` Results with debug verbose: ```[chain/start] [1:chain:AgentExecutor] Entering Chain run with input: { "input": "whats the lyrics of Ezhel Pofuduk" } [llm/start] [1:chain:AgentExecutor > 2:llm:ChatOpenAI] Entering LLM run with input: { "prompts": [ "System: Your name is BOTIFY and try to answer the question, you can use the tools..\nHuman: whats the lyrics of Ezhel Pofuduk" ] } [llm/end] [1:chain:AgentExecutor > 2:llm:ChatOpenAI] [1.89s] Exiting LLM run with output: { "generations": [ [ { "text": "Sorry, I don't have access to the lyrics of specific songs. You can search for the lyrics of \"Ezhel Pofuduk\" online.", "generation_info": { "finish_reason": "stop" }, "message": { "lc": 1, "type": "constructor", "id": [ "langchain", "schema", "messages", "AIMessage" ], "kwargs": { "content": "Sorry, I don't have access to the lyrics of specific songs.

You can search for the lyrics of \"Ezhel Pofuduk\" online." ``` Questions: **1)Where are the tools in this prompt?** **2)How can you force to use one of the tools as a last resort?** Btw I know that it has the tools because it sometimes uses. Example 2: ``` response = agent.run("whats the lyrics of Ezhel Pofuduk") ``` Result: ``` [chain/start] [1:chain:AgentExecutor] Entering Chain run with input: { "input": "NVDIA Share price?" } [llm/start] [1:chain:AgentExecutor > 2:llm:ChatOpenAI] Entering LLM run with input: { "prompts": [ "System: Your name is BOTIFY and try to answer the question, you can use the tools.\nHuman: NVDIA Share price?" ] } [llm/end] [1:chain:AgentExecutor > 2:llm:ChatOpenAI] [1.44s] Exiting LLM run with output: { "generations": [ [ { "text": "", "generation_info": { "finish_reason": "function_call" }, "message": { "lc": 1, "type": "constructor", "id": [ "langchain", "schema", "messages", "AIMessage" ], "kwargs": { "content": "", "additional_kwargs": { "function_call": { "name": "Search", "arguments": "{\n \"__arg1\": \"NVIDIA share price\"\n}" } } } } } ] ], "llm_output": { "token_usage": { "prompt_tokens": 180, "completion_tokens": 18, "total_tokens": 198 }, "model_name": "gpt-3.5-turbo-0613" }, "run": null } [tool/start] [1:chain:AgentExecutor > 3:tool:Search] Entering Tool run with input: "NVIDIA share price" [tool/end] [1:chain:AgentExecutor > 3:tool:Search] [1.56s] Exiting Tool run with output: "439,89 -15,92 (%3,49)" [llm/start] [1:chain:AgentExecutor > 4:llm:ChatOpenAI] Entering LLM run with input: { "prompts": [ "System: Your name is BOTIFY and try to answer the question, you can use the tools.\nHuman: NVDIA Share price?\nAI: {'name': 'Search', 'arguments': '{\\n \"__arg1\": \"NVIDIA share price\"\\n}'}\nFunction: 439,89 -15,92 (%3,49)" ] } [llm/end] [1:chain:AgentExecutor > 4:llm:ChatOpenAI] [2.12s] Exiting LLM run with output: { "generations": [ [ { "text": "NVIDIA share price is $439.89, down $15.92 (3.49%).", "generation_info": { "finish_reason": "stop" }, "message": { "lc": 1, "type": "constructor", "id": [ "langchain", "schema", "messages", "AIMessage" ], "kwargs": { "content": "NVIDIA share price is $439.89, down $15.92 (3.49%).", "additional_kwargs": {} } } } ] ], "llm_output": { "token_usage": { "prompt_tokens": 217, "completion_tokens": 21, "total_tokens": 238 }, "model_name": "gpt-3.5-turbo-0613" }, "run": null } [chain/end] [1:chain:AgentExecutor] [5.12s] Exiting Chain run with output: { "output": "NVIDIA share price is $439.89, down $15.92 (3.49%)." } ``` How can see my tools in the prompt. This is needed because I would to create my custom Agent so I dont give the default prompts that is used in the each agent type. ### Information - [ ] The official example notebooks/scripts - [X] My own modified scripts ### Related Components - [X] LLMs/Chat Models - [ ] Embedding Models - [X] Prompts / Prompt Templates / Prompt Selectors - [ ] Output Parsers - [ ] Document Loaders - [ ] Vector Stores / Retrievers - [ ] Memory - [X] Agents / Agent Executors - [X] Tools / Toolkits - [ ] Chains - [X] Callbacks/Tracing - [ ] Async ### Reproduction ``` ################# langchain.debug = True tools = [ # Tool(name="Weather", func=weather_service.get_response, description="..."), # Tool(name="Finance", func=finance_service.get_response, description="..."), Tool( name="Search", func=search.run, description="useful for when you need to search internet for question. You should ask targeted questions" ), ] # Initialize the agent llm = ChatOpenAI(temperature=0, model="gpt-3.5-turbo-0613", openai_api_key=os.getenv("OPENAPI_SECRET_KEY")) system_message = SystemMessage( content="Your name is BOTIFY and try to answer the question, you can use the tools") agent_kwargs = { "system_message": system_message, } agent = initialize_agent(tools, llm, agent=AgentType.OPENAI_FUNCTIONS, agent_kwargs=agent_kwargs, verbose=True) response = agent.run("NVDIA Share price?") ``` ### Expected behavior I was expecting to see the tools in my prompts as well.

Description: This PR changes the import section of the `PydanticOutputParser` notebook. * Import from `langchain.pydantic_v1` instead of `pydantic` * Remove unused imports Issue: running the notebook as written, when pydantic v2 is installed, results in the following: ```python PydanticDeprecatedSince20: Pydantic V1 style `@validator` validators are deprecated. You should migrate to Pydantic V2 style `@field_validator` validators, see the migration guide for more details. Deprecated in Pydantic V2.0 to be removed in V3.0. See Pydantic V2 Migration Guide at https://errors.pydantic.dev/2.3/migration/ ``` [...] ```python PydanticUserError: The `field` and `config` parameters are not available in Pydantic V2, please use the `info` parameter instead. For further information visit https://errors.pydantic.dev/2.3/u/validator-field-config-info ```

**Description:** This commit adds a vector store for the Postgres-based vector database (`TimescaleVector`). Timescale Vector(https://www.timescale.com/ai) is PostgreSQL++ for AI applications. It enables you to efficiently store and query billions of vector embeddings in `PostgreSQL`: - Enhances `pgvector` with faster and more accurate similarity search on 1B+ vectors via DiskANN inspired indexing algorithm. - Enables fast time-based vector search via automatic time-based partitioning and indexing. - Provides a familiar SQL interface for querying vector embeddings and relational data. Timescale Vector scales with you from POC to production: - Simplifies operations by enabling you to store relational metadata, vector embeddings, and time-series data in a single database. - Benefits from rock-solid PostgreSQL foundation with enterprise-grade feature liked streaming backups and replication, high-availability and row-level security. - Enables a worry-free experience with enterprise-grade security and compliance. Timescale Vector is available on Timescale, the cloud PostgreSQL platform. (There is no self-hosted version at this time.) LangChain users get a 90-day free trial for Timescale Vector. <!-- Thank you for contributing to LangChain!

**Description:** Pass HuggingFacePipeline kwargs at inference, not just when it's instantiated, so that changing the arguments of the pipeline would actually affect the result, e.g. ```python from langchain import HuggingFacePipeline pipe = HuggingFacePipeline.from_model_id( task="text-generation", device=1, model_id="meta-llama/Llama-2-7b-chat-hf", pipeline_kwargs={ 'max_length': 100, 'temperature': 0.1 }, ) pipe('hello, how are you?') # this can return up to 100 tokens w temperature 0.1 pipe.pipeline_kwargs['temperature'] = 0.9 pipe.pipeline_kwargs['max_length'] = 50 pipe('hello, how are you?') # this can return up to 50 tokens w temperature 0.9 ``` **Issue:** None **Dependencies:** None **Tag maintainer:** None **Twitter handle:** None

- **Description:** A Document Loader for MongoDB - **Issue:** n/a - **Dependencies:** Motor, the async driver for MongoDB - **Tag maintainer:** n/a - **Twitter handle:** pigpenblue Note that an initial mongodb document loader was created 4 months ago, but the [PR ](https://github.com/langchain-ai/langchain/pull/4285)was never pulled in. @leo-gan had commented on that PR, but given it is extremely far behind the master branch and a ton has changed in Langchain since then (including repo name and structure), I rewrote the branch and issued a new PR with the expectation that the old one can be closed. Please reference that old PR for comments/context, but it can be closed in favor of this one. Thanks!

### System Info I am using VertexAI model to parse data in a document. Since the documents are large, I am trying to increase the max_output_tokens parameter for "chat-bison-32k" model. I am not able to change this parameter and my output gets truncated after a certain token limit is reached. Is there a way to increase the output token limit?

- **Description:** be able to use langchain with other version than tiktoken 0.3.3 i.e 0.5.1 - **Issue:** cannot installed the conda-forge version since it applied all optional dependency: https://github.com/conda-forge/langchain-feedstock/pull/85 replace "^0.3.2" by "">=0.3.2,<0.6.0" and "^3.9" by python=">=3.9" Tested with python 3.10, langchain=0.0.288 and tiktoken==0.5.0 - **Clarification**: The langchain package on pypi have only the mandatory dependencies. Is there another one with all optional dependencies and similar to have is done in conda-forge ? Before I saw langchain[all] but doesn't seems to exist anymore.

### Issue you'd like to raise. ## Description I use the Chinook database as an example. ![image](https://github.com/langchain-ai/langchain/assets/91650059/200c3663-f0e0-4cc3-98be-fcad39dff38c) I will create a AI customer service system. The user provides the trackid and question. In addition to providing answers, the system will also provide track, album and artist information for the trackid. For examples: [Question] [Answer] [Fixed information] Q: Help me check the selling price of trackid 1024. A: The selling price of trackid 1024 is $0.99. - Track ID: 1024 - Song: Wind Up - Album: The Colour And The Shape - Artist: Foo Fighters ## Build chain ``` from langchain.chat_models import ChatOpenAI from langchain.utilities import SQLDatabase from langchain_experimental.sql import SQLDatabaseChain db = SQLDatabase.from_uri( "sqlite:///Chinook.db", include_tables=["Track", "Album", "Artist"], ) llm = ChatOpenAI(temperature=0, model="gpt-3.5-turbo", verbose=True) db_chain = SQLDatabaseChain.from_llm(llm, db, use_query_checker=True, verbose=True) ``` ## Case 1 + Input ``` db_chain.run("Help me check the selling price of trackid 1024.") ``` + Output ``` > Entering new SQLDatabaseChain chain... Help me check the selling price of trackid 1024. SQLQuery:SELECT "UnitPrice" FROM "Track" WHERE "TrackId" = 1024; SQLResult: [(0.99,)] Answer:Final answer here: The selling price of trackid 1024 is $0.99. > Finished chain. ``` + Explain ``` Just ask for answers. Get the right answer. ``` ## Case 2 + Input ``` db_chain.run( "Help me check the selling price of trackid 1024, and use markdown items to list track.id, track.name, albums.title, and artist.name." ) ``` + Output ``` > Entering new SQLDatabaseChain chain... Help me check the selling price of trackid 1024, and use markdown items to list track.id, track.name, albums.title, and artist.name. SQLQuery:SELECT "Track"."TrackId", "Track"."Name", "Album"."Title", "Artist"."Name" FROM "Track" JOIN "Album" ON "Track"."AlbumId" = "Album"."AlbumId" JOIN "Artist" ON "Album"."ArtistId" = "Artist"."ArtistId" WHERE "Track"."TrackId" = 1024 SQLResult: [(1024, 'Wind Up', 'The Colour And The Shape', 'Foo Fighters')] Answer:The selling price of trackid 1024 is not provided in the given tables. > Finished chain. ``` + Explain ``` Ask for answers and fixed information at the same time. LLM will pay attention to the fixed information. Forget the most important question of asking about price. ``` ### Suggestion: Hope `SQLDatabaseChain` supports returning fixed infomation for specific relational columns.

### System Info langchain 0.0.291 Python 3.9.6 Platform = Unix I built an chatbot using langchain and GPT 3.5-turbo as LLM. I am running into issues of the bot not being able to appropriately response to social nuances (e.g. "Thank you.", "That's all, goodbye", etc.). Instead of picking up on social cues, it start providing info from the context files. Example conversation: ``` Human - Good morning AI - Good morning, how can I help you? Human - Actually, nothing. Goodbye. AI - *Starts talking about information in the context files* ``` I have went through the code and I found out that you are calling the LLM twice - once to generate a proper question based on the history and then second time to provide an answer for the user. The issue is related to the first call, in which the LLM generates incorrect question. I say "Goodbye" and the `generations` object from the first call returns something like "What can our company do for you?". Regarding my code. I am using FAISS to store vectors and I am using the default implementation (4 documents being retrieved). I am not using LangChain in-build memory, because it doesn't allow to maintain multiple conversations with multiple users. I implemented it myself in the same way as `ConversationBufferMemory` is implemented - an array of HumanMessage and AIMessage. And it is working, it remembers topics from the past. I tried modifying my prompt many times, to being very specific and also to the very simplest: ``` QA_PROMPT = """ You are a helpful assistant that is supposed to help and maintain polite conversation. <<<{context}>>> Question: {question} Helpful answer: """ ``` The code is simple: ``` qa_prompt_template = PromptTemplate(input_variables=['context', 'question'], template=QA_PROMPT) llm = ChatOpenAI(model_name='gpt-3.5-turbo', temperature=0, openai_api_key=OPENAI_API_KEY, max_tokens=512) vectorstore = FAISS.from_documents(documents, embeddings) qa = ConversationalRetrievalChain.from_llm(llm, vectorstore.as_retriever(), combine_docs_chain_kwargs={'prompt': qa_prompt_template}) ... response = qa({'question': question, 'chat_history': chat_history}) ``` Also, I have found out, that if I always send completely empty chat history, the chatbot answers properly. So it has to do something with the history or with the context files. Can somebody please help me understand why does the model formulate the question incorrectly? ### Who can help? @agola11 @hwchase17 ### Information - [ ] The official example notebooks/scripts - [X] My own modified scripts ### Related Components - [X] 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 Code provided in the description. Not sure if you can reproduce the behaviour without the context files. ### Expected behavior The LLM is supposed to response like it normally would. That means a person-like conversation with social cues and responding to what it was actually asked.

### Issue you'd like to raise. Hi, I am trying to make a chatbot with a LLM based on LLaMa2. When I use the memory (ConversationBufferWindowMemory), it creates a default prompt like: """ Human: input AI: output Human: input """ However, with LLaMa2 I need to create a prompt like: """ [INST] {input} [/INST] {output} [INST] {input} [/INST] """ I discovered that I can change the "Human" and "AI" prefixes, but I can’t delete the ":", so I am getting: """ : [INST] {input} [/INST] : {output} : [INST] {input} [/INST] """ Is there any way I can modify the whole prefix? Thanks ### Suggestion: _No response_

…parameters. In Langchain's `dumps()` function, I've added a `**kwargs` parameter. This allows users to pass additional parameters to the underlying `json.dumps()` function, providing greater flexibility and control over JSON serialization. Many parameters available in `json.dumps()` can be useful or even necessary in specific situations. For example, when using an Agent with return_intermediate_steps set to true, the output is a list of AgentAction objects. These objects can't be serialized without using Langchain's `dumps()` function. The issue arises when using the Agent with a language other than English, which may contain non-ASCII characters like 'é'. The default behavior of `json.dumps()` sets ensure_ascii to true, converting `{"name": "José"}` into `{"name": "Jos\u00e9"}`. This can make the output hard to read, especially in the case of intermediate steps in agent logs. By allowing users to pass additional parameters to `json.dumps()` via Langchain's dumps(), we can solve this problem. For instance, users can set `ensure_ascii=False` to maintain the original characters. This update also enables users to pass other useful `json.dumps()` parameters like `sort_keys`, providing even more flexibility. The implementation takes into account edge cases where a user might pass a "default" parameter, which is already defined by `dumps()`, or an "indent" parameter, which is also predefined if `pretty=True` is set.

hi team, Can I use the multiple LLM in agent? Use different model by action. Because I found gpt-4 took too much token in my agent, I just want gpt-4 to handle some action and gpt-3 to handle other action to reduce the token usage. Is it workable?

**Description:** The previous behaviour was causing an error, because the keys input resp. output did not exist in the passed parameters inputs resp. outputs. Now, all keys are tracked in aim as texts and from the input_documents, the page content is tracked. Additionally the structure of the tracking is more useful for getting an overview of the run. **Issue:** new version of pull request 6161 **Dependencies:** aim **Tag maintainer:** @leo-gan **Twitter handle:** no

- **Description:** Changed the `_get_relevant_documents` function inside `SelfQueryRetriever` and `_call` function inside `LLMRouterChain` to avoid using the deprecated `predict_and_parse` function inside `LLMChain`, and not getting the (annoying) warning message. - **Issue:** #10606 and #10462 for `SelfQueryRetriever`, and #6819 for `LLMRouterChain` - **Dependencies:** None, - **Tag maintainer:** @baskaryan, - **Twitter handle:** @schnell_dj **PS :** This is my first PR ever, and I am far from being a pro Dev. So your feedback, comments and guidance are more than welcome!

Description: this PR changes the `ArcGISLoader` to set `return_all_records` to `False` when `result_record_count` is provided as a keyword argument. Previously, `return_all_records` was `True` by default and this made the API ignore `result_record_count`. Issue: `ArcGISLoader` would ignore `result_record_count` unless user also passed `return_all_records=False`.

We should be able to expect that the vectorsotre now includes doc1_1, doc1_2, and doc2, but not doc1_1, doc1_2, and doc1_2. # Reason In `index`, the original code is ```python uids = [] docs_to_index = [] for doc, hashed_doc, doc_exists in zip(doc_batch, hashed_docs, exists_batch): if doc_exists: # Must be updated to refresh timestamp. record_manager.update([hashed_doc.uid], time_at_least=index_start_dt) num_skipped += 1 continue uids.append(hashed_doc.uid) docs_to_index.append(doc) ``` In the aforementioned example, `len(doc_batch) == 4`, but `len(hashed_docs) == len(exists_batch) == 3`. This is because the deduplication of input documents [doc1_1, doc1_2, doc1_2, doc2] is [doc1_1, doc1_2, doc2]. So `index` insert doc1_1, doc1_2, doc1_2 with the uid of doc1_1, doc1_2, doc2.

### Feature request It would be great to see **thought instruction** be implemented as an alternative to chain of thought (CoT) prompting. **Thought instruction** is proposed as an alternative to chain of thought (CoT) prompting for a more nuanced approach to software development. It involves explicitly addressing specific problem-solving thoughts in instructions, akin to solving subtasks in a sequential manner. The method includes role swapping to inquire about unimplemented methods or explain feedback messages caused by bugs. This process fosters a clearer understanding of the existing code and identifies specific gaps that need addressing. By doing so, **thought instruction** aims to mitigate code hallucinations and enable a more accurate, context-aware approach to code completion, resulting in more reliable and comprehensive code outputs. ### Motivation See ChatDev ([source code](https://github.com/OpenBMB/ChatDev/tree/main) and [paper](https://arxiv.org/pdf/2307.07924)) for inspiration. ### Your contribution Idea

### Issue you'd like to raise. Hi , I'm trying to see how I can put a system message for my chain to tell him that for example "Your name is XX". I've tried a lot of things and saw a lot of issues resolved and documentations but they never worked... Any help will be appreciated. here is the code of my chain.ts: ` import {OpenAI} from "langchain/llms/openai"; import {pinecone} from "@/utils/pinecone-client"; import {PineconeStore} from "langchain/vectorstores/pinecone"; import {OpenAIEmbeddings} from "langchain/embeddings/openai"; import {ConversationalRetrievalQAChain} from "langchain/chains"; import { PromptTemplate } from "langchain/prompts"; import { ChatOpenAI } from "langchain/chat_models/openai"; async function initChain() { const model = new ChatOpenAI({ modelName: "gpt-3.5-turbo", temperature: 0, }); const pineconeIndex = pinecone.Index('canada'); const vectorStore = await PineconeStore.fromExistingIndex( new OpenAIEmbeddings({}), { pineconeIndex: pineconeIndex, textKey: 'text', }, ); return ConversationalRetrievalQAChain.fromLLM( model, vectorStore.asRetriever(), {returnSourceDocuments: true} ); return ConversationalRetrievalQAChain.fromLLM( model, vectorStore.asRetriever(), {returnSourceDocuments: true}, ); } export const chain = await initChain()` ### Suggestion: _No response_

### Issue you'd like to raise. As noted here: #10462 and #6819 I've realized I'm thousands of miles away from having the skills to fix this and make a PR (I'm not a Pro Dev) in my attempt to update the `SelfQueryRetriever`. However, I think this will be a great learning opportunity, with help from someone who knows what they're doing (@agola11). After taking a close look at the `SelfQueryRetriever` [source](https://api.python.langchain.com/en/latest/_modules/langchain/retrievers/self_query/base.html#SelfQueryRetriever), I noticed that what needs to be updated is this part from the `_get_relevant_documents` function: ``` structured_query = cast( StructuredQuery, self.llm_chain.predict_and_parse( callbacks=run_manager.get_child(), **inputs ), ) ``` I even ran `SelfQueryRetriever` (in my ignorance) with just `self.llm_chain.predict` to see what it did, but I got the JSON as the output and the vectorstore complaining it was expecting a tuple: ``` in RedisTranslator.visit_structured_query(self, structured_query) 91 def visit_structured_query( 92 self, structured_query: StructuredQuery 93 ) -> Tuple[str, dict]: ---> 94 if structured_query.filter is None: 95 kwargs = {} 96 else: AttributeError: 'str' object has no attribute 'filter' ``` I also took a look at the `predict_and_parse` method in the `LLMChain` [source](https://api.python.langchain.com/en/latest/_modules/langchain/chains/llm.html#LLMChain.predict_and_parse). And here's where I knew I was biting way more than I could (ever) chew. ### Suggestion: Can someone please guide me to replace and update the `_get_relevant_documents` function? I think I need to find a way to convert the JSON to the required tuple, but I can't figure out how. Am I on the right track?
