  • This is a bug, not a usage question. For questions, please use the LangChain Forum (https://forum.langchain.com/).
  • I added a clear and detailed title that summarizes the issue.
  • I read what a minimal reproducible example is (https://stackoverflow.com/help/minimal-reproducible-example).
  • I included a self-contained, minimal example that demonstrates the issue INCLUDING all the relevant imports. The code run AS IS to reproduce the issue.

Example Code

"""State definitions for Research Setup graph."""

from typing import Annotated, Optional

from langgraph.graph.ui import AnyUIMessage, ui_message_reducer
from typing_extensions import TypedDict


class ResearchSetupState(TypedDict):
    """State for the Research Setup flow.

    Handles both Flow A (Use my segments) and Flow B (I want to create segments).
    """

    # Flow control

    # Generative UI messages
    ui: Annotated[list[AnyUIMessage], ui_message_reducer]

Error Message and Stack Trace (if applicable)

Import "langgraph.graph.ui" could not be resolved

Description

I am following this doc https://docs.langchain.com/langsmith/generative-ui-react#python

I think inside
the graph(libs/langgraph/langgraph/graph) ui.py (libs/langgraph/langgraph/graph/ui.py) is not initialised or imported

from langgraph.graph.graph import END, START, Graph
from langgraph.graph.message import MessageGraph, MessagesState, add_messages
from langgraph.graph.state import StateGraph

__all__ = [
    "END",
    "START",
    "Graph",
    "StateGraph",
    "MessageGraph",
    "add_messages",
    "MessagesState",
]
