小铭	cf5803e44c	Add ToolException that a tool can throw. (#5050 ) # Add ToolException that a tool can throw This is an optional exception that tool throws when execution error occurs. When this exception is thrown, the agent will not stop working,but will handle the exception according to the handle_tool_error variable of the tool,and the processing result will be returned to the agent as observation,and printed in pink on the console.It can be used like this: ```python from langchain.schema import ToolException from langchain import LLMMathChain, SerpAPIWrapper, OpenAI from langchain.agents import AgentType, initialize_agent from langchain.chat_models import ChatOpenAI from langchain.tools import BaseTool, StructuredTool, Tool, tool from langchain.chat_models import ChatOpenAI llm = ChatOpenAI(temperature=0) llm_math_chain = LLMMathChain(llm=llm, verbose=True) class Error_tool: def run(self, s: str): raise ToolException('The current search tool is not available.') def handle_tool_error(error) -> str: return "The following errors occurred during tool execution:"+str(error) search_tool1 = Error_tool() search_tool2 = SerpAPIWrapper() tools = [ Tool.from_function( func=search_tool1.run, name="Search_tool1", description="useful for when you need to answer questions about current events.You should give priority to using it.", handle_tool_error=handle_tool_error, ), Tool.from_function( func=search_tool2.run, name="Search_tool2", description="useful for when you need to answer questions about current events", return_direct=True, ) ] agent = initialize_agent(tools, llm, agent=AgentType.ZERO_SHOT_REACT_DESCRIPTION, verbose=True, handle_tool_errors=handle_tool_error) agent.run("Who is Leo DiCaprio's girlfriend?

Tian Wei	d7f807b71f	Add AzureCognitiveServicesToolkit to call Azure Cognitive Services API (#5012 ) # Add AzureCognitiveServicesToolkit to call Azure Cognitive Services API: achieve some multimodal capabilities This PR adds a toolkit named AzureCognitiveServicesToolkit which bundles the following tools: - AzureCogsImageAnalysisTool: calls Azure Cognitive Services image analysis API to extract caption, objects, tags, and text from images. - AzureCogsFormRecognizerTool: calls Azure Cognitive Services form recognizer API to extract text, tables, and key-value pairs from documents. - AzureCogsSpeech2TextTool: calls Azure Cognitive Services speech to text API to transcribe speech to text. - AzureCogsText2SpeechTool: calls Azure Cognitive Services text to speech API to synthesize text to speech. This toolkit can be used to process image, document, and audio inputs. --------- Co-authored-by: Dev 2049 <dev.dev2049@gmail.com>	1 year ago
Eduard van Valkenburg	1cb04f2b26	PowerBI major refinement in working of tool and tweaks in the rest (#5090 ) # PowerBI major refinement in working of tool and tweaks in the rest I've gained some experience with more complex sets and the earlier implementation had too many tries by the agent to create DAX, so refactored the code to run the LLM to create dax based on a question and then immediately run the same against the dataset, with retries and a prompt that includes the error for the retry. This works much better! Also did some other refactoring of the inner workings, making things clearer, more concise and faster.	1 year ago
Deepak S V	49ca02711e	Improved query, print & exception handling in REPL Tool (#4997 ) Update to pull request https://github.com/hwchase17/langchain/pull/3215 Summary: 1) Improved the sanitization of query (using regex), by removing python command (since gpt-3.5-turbo sometimes assumes python console as a terminal, and runs python command first which causes error). Also sometimes 1 line python codes contain single backticks. 2) Added 7 new test cases. For more details, view the previous pull request. --------- Co-authored-by: Deepak S V <svdeepak99@users.noreply.github.com>	1 year ago
Eugene Yurtsev	06e524416c	power bi api wrapper integration tests & bug fix (#4983 ) # Powerbi API wrapper bug fix + integration tests - Bug fix by removing `TYPE_CHECKING` in in utilities/powerbi.py - Added integration test for power bi api in utilities/test_powerbi_api.py - Added integration test for power bi agent in agent/test_powerbi_agent.py - Edited .env.examples to help set up power bi related environment variables - Updated demo notebook with working code in docs../examples/powerbi.ipynb - AzureOpenAI -> ChatOpenAI Notes: Chat models (gpt3.5, gpt4) are much more capable than davinci at writing DAX queries, so that is important to getting the agent to work properly. Interestingly, gpt3.5-turbo needed the examples=DEFAULT_FEWSHOT_EXAMPLES to write consistent DAX queries, so gpt4 seems necessary as the smart llm. Fixes #4325 ## Before submitting Azure-core and Azure-identity are necessary dependencies check integration tests with the following: `pytest tests/integration_tests/utilities/test_powerbi_api.py` `pytest tests/integration_tests/agent/test_powerbi_agent.py` You will need a power bi account with a dataset id + table name in order to test. See .env.examples for details. ## Who can review? @hwchase17 @vowelparrot --------- Co-authored-by: aditya-pethe <adityapethe1@gmail.com>	1 year ago

Samuli Rauatmaa	66828ad231	add the existing OpenWeatherMap tool to the public api (#4292 ) [OpenWeatherMapAPIWrapper](`f70e18a5b3/docs/modules/agents/tools/examples/openweathermap.ipynb`) works wonderfully, but the _tool_ itself can't be used in master branch. - added OpenWeatherMap tool to the public api, to be loadable with `load_tools` by using "openweathermap-api" tool name (that name is used in the existing [docs](`aff33d52c5/docs/modules/agents/tools/getting_started.md`), at the bottom of the page) - updated OpenWeatherMap tool's description to make the input format match what the API expects (e.g. `London,GB` instead of `'London,GB'`) - added [ecosystem documentation page for OpenWeatherMap](`f9c41594fe/docs/ecosystem/openweathermap.md`) - added tool usage example to [OpenWeatherMap's notebook](`f9c41594fe/docs/modules/agents/tools/examples/openweathermap.ipynb`) Let me know if there's something I missed or something needs to be updated! Or feel free to make edits yourself if that makes it easier for you 🙂	1 year ago

Prerit Das	2747ccbcf1	Allow custom base Zapier prompt (#4213 ) Currently, all Zapier tools are built using the pre-written base Zapier prompt. These small changes (that retain default behavior) will allow a user to create a Zapier tool using the ZapierNLARunTool while providing their own base prompt. Their prompt must contain input fields for zapier_description and params, checked and enforced in the tool's root validator. An example of when this may be useful: user has several, say 10, Zapier tools enabled. Currently, the long generic default Zapier base prompt is attached to every single tool, using an extreme number of tokens for no real added benefit (repeated). User prompts LLM on how to use Zapier tools once, then overrides the base prompt. Or: user has a few specific Zapier tools and wants to maximize their success rate. So, user writes prompts/descriptions for those tools specific to their use case, and provides those to the ZapierNLARunTool. A consideration - this is the simplest way to implement this I could think of... though ideally custom prompting would be possible at the Toolkit level as well. For now, this should be sufficient in solving the concerns outlined above.	1 year ago

More changes to come in separate PR) - Move the `Tool` and decorator definitions to `langchain/tools/base.py` (but still export from `langchain.agents`) - Add scene explain to the load_tools() function - Add unit tests for public apis for the langchain.tools and langchain.agents modules	1 year ago

Ankush Gola	82baecc892	Add a SQL agent for interacting with SQL Databases and JSON Agent for interacting with large JSON blobs (#1150 ) This PR adds * `ZeroShotAgent.as_sql_agent`, which returns an agent for interacting with a sql database. This builds off of `SQLDatabaseChain`. The main advantages are 1) answering general questions about the db, 2) access to a tool for double checking queries, and 3) recovering from errors * `ZeroShotAgent.as_json_agent` which returns an agent for interacting with json blobs. * Several examples in notebooks --------- Co-authored-by: Harrison Chase <hw.chase.17@gmail.com>	1 year ago
