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?

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.

Leonid Ganeline	e2d7677526	docs: compound ecosystem and integrations (#4870 ) # Docs: compound ecosystem and integrations Problem statement: We have a big overlap between the References/Integrations and Ecosystem/LongChain Ecosystem pages. It confuses users. It creates a situation when new integration is added only on one of these pages, which creates even more confusion. - removed References/Integrations page (but move all its information into the individual integration pages - in the next PR). - renamed Ecosystem/LongChain Ecosystem into Integrations/Integrations. I like the Ecosystem term. It is more generic and semantically richer than the Integration term. But it mentally overloads users. The `integration` term is more concrete. UPDATE: after discussion, the Ecosystem is the term. Ecosystem/Integrations is the page (in place of Ecosystem/LongChain Ecosystem). As a result, a user gets a single place to start with the individual integration.	1 year ago

keenangraham	bcce9a3a92	Fix age inconsistency in plan and execute Jupyter notebook example (#4814 ) The current example in https://python.langchain.com/en/latest/modules/agents/plan_and_execute.html has inconsistent reasoning step (observing 28 years and thinking it's 26 years): ``` Observation: 28 years Thought:Based on my search, Gigi Hadid's current age is 26 years old. Action: { "action": "Final Answer", "action_input": "Gigi Hadid's current age is 26 years old." } ``` Guessing this is model noise. Rerunning seems to give correct answer of 28 years.	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!
