Who can help? @hwchase17 Parameters: langchain_tool (LangChainTool) – A LangChain tool to wrap Examples Use the PythonAstREPLTool from the langchain_experimental package to create a tool that allows you In this part of our project, we’re going to make our own agent tool that can understand and work with code. fake import FakeListLLM from langchain. llms. 10 This bug is reproducible on older langchain version (0. Tools can be passed to chat PythonAstREPLTool implements the standard RunnableInterface. Python REPL 有时候，对于复杂的计算，与其让LLM直接生成答案，不如让LLM生成计算答案的代码，然后运行该代码来获得答案。为了方便这样做，我们提供了一个简单的Python REPL来执行命令。 这个接口只会返回打印出来的内容 - 因 文章浏览阅读1187次。对于您提到的 "langchain PythonAstREPLTool" 和 "PythonREPLTool"，我可以给您提供一些基本信息。 "langchain PythonAstREPLTool" 是一 LLMs are great for building question-answering systems over various types of data sources. PythonREPLTool ¶ class langchain. The PythonAstREPLTool handles local variables through the 'locals' attribute, which is a dictionary. It allows an LLM to iteratively execute code while maintaining the inputs and outputs extra_tools (Sequence[BaseTool]) – Additional tools to give to agent on top of a PythonAstREPLTool. agent_types import class langchain_experimental. Initialize the tool. PythonREPLTool [source] ¶ Bases: BaseTool Tool for running python code in a REPL. engine (Literal['pandas', 'modin']) – One of “modin” or “pandas”. Defaults Checked other resources I added a very descriptive title to this question. However, PythonREPLTool # class langchain_experimental. langchain_experimental. PythonAstREPLTool ¶ Note PythonAstREPLTool implements the standard Runnable Interface. ClassesFunctions Here is an example of how to define and use the PythonREPLTool correctly: Define the Tool from pydantic import BaseModel, Field from langchain_core.

ClassesFunctions Overview The tool abstraction in LangChain associates a Python function with a schema that defines the function's name, description and expected arguments. I searched the LangChain documentation with the integrated search. PythonAstREPLTool(*, name: str = 'python_repl_ast', description: To add few-shot examples to the PythonAstREPLTool, you can include them directly in the description parameter when initializing the tool.

This parameter is used to Parameters: langchain_tool (LangChainTool) – A LangChain tool to wrap Examples Use the PythonAstREPLTool from the langchain_experimental package to create a tool that allows you From your code, it seems like you're trying to pass the dataframe 'df' to the PythonAstREPLTool in LangChain. The problem is that it gets the action_input step of Sometimes, for complex calculations, rather than have an LLM generate the answer directly, it can be better to have the LLM generate code to calculate the answer, and then run that code Overview The tool abstraction in LangChain associates a Python function with a schema that defines the function's name, description and expected arguments. tools PythonRepl tools and Pandas/Xorbits/Spark/Python agents are moving to langchain_experimental """A tool for running python code in a REPL. agents import AgentType from langchain_experimental. agents import initialize_agent from langchain.
