morpheus.llm.nodes.langchain_agent_node.LangChainAgentNode

class LangChainAgentNode(agent_executor, replace_exceptions=False, replace_exceptions_value=None)[source]

Bases: morpheus._lib.llm.LLMNodeBase

Executes a LangChain agent in an LLMEngine

Parameters

agent_executor
replace_exceptions
replace_exceptions_value

Methods

`execute`(self, context)	Execute the current node with the given `context` instance.
`get_input_names`(self)	Get the input names for the node.

async execute(self: morpheus._lib.llm.LLMNodeBase, context: morpheus._lib.llm.LLMContext) → Awaitable[morpheus._lib.llm.LLMContext][source]

Execute the current node with the given context instance.

All inputs for the given node should be fetched from the context, typically by calling either context.get_inputs to fetch all inputs as a dict, or context.get_input to fetch a specific input.

Similarly the output of the node is written to the context using context.set_output.

Parameters

context : morpheus._lib.llm.LLMContext

get_input_names(self: morpheus._lib.llm.LLMNodeBase) → List[str][source]

Get the input names for the node.

Returns

list[str]
