class Alias(name: 'str', alias: 'str')

Bases: object

alias: str

name: str

class CodeBlock(code: str, language: str)

Bases: object

A code block extracted fromm an agent message.

code: str

language: str

class CodeExecutor

Bases: ABC, ComponentBase[BaseModel]

Executes code blocks and returns the result.

component_type: ClassVar[ComponentType] = 'code_executor'

The logical type of the component.

abstract async execute_code_blocks(code_blocks: List[CodeBlock], cancellation_token: CancellationToken) → CodeResult

Execute code blocks and return the result.

This method should be implemented by the code executor.

Parameters:

code_blocks (List[CodeBlock]) – The code blocks to execute.

Returns:

CodeResult – The result of the code execution.

Raises:

• ValueError – Errors in user inputs

• TimeoutError – Code execution timeouts

• CancelledError – CancellationToken evoked during execution

abstract async restart() → None

Restart the code executor.

This method should be implemented by the code executor.

This method is called when the agent is reset.

class CodeResult(exit_code: int, output: str)

Bases: object

Result of a code execution.

exit_code: int

output: str

with_requirements(python_packages: Sequence[str] = [], global_imports: Sequence[str | ImportFromModule | Alias] = []) → Callable[[Callable[[P], T]], FunctionWithRequirements[T, P]]

Decorate a function with package and import requirements for code execution environments.

This decorator makes a function available for reference in dynamically executed code blocks by wrapping it in a FunctionWithRequirements object that tracks its dependencies. When the decorated function is passed to a code executor, it can be imported by name in the executed code, with all dependencies automatically handled.

Parameters:

• python_packages (Sequence[str], optional) – Python packages required by the function. Can include version specifications (e.g., [“pandas>=1.0.0”]). Defaults to [].

• global_imports (Sequence[Import], optional) – Import statements required by the function. Can be strings (“numpy”), ImportFromModule objects, or Alias objects. Defaults to [].

Returns:

Callable[[Callable[P, T]], FunctionWithRequirements[T, P]] – A decorator that wraps the target function, preserving its functionality while registering its dependencies.
