Lesson 5: Human in the LoopĀ¶
Note: This notebook is running in a later version of langgraph that it was filmed with. The later version has a couple of key additions:
- Additional state information is stored to memory and displayed when using
get_state()orget_state_history(). - State is additionally stored every state transition while previously it was stored at an interrupt or at the end. These change the command output slightly, but are a useful addtion to the information available.

Extra PracticeĀ¶
Build a small graphĀ¶
This is a small simple graph you can tinker with if you want more insight into controlling state memory.

Define a simple 2 node graph with the following state: -lnode: last node -scratch: a scratchpad location -count : a counter that is incremented each step
InĀ [41]:

Run it!Ā¶
Now, set the thread and run!
InĀ [46]:
Copied!
thread = {"configurable": {"thread_id": str(1)}}
graph.invoke({"count":0, "scratch":"hi"},thread)
thread = {"configurable": {"thread_id": str(1)}} graph.invoke({"count":0, "scratch":"hi"},thread)

Out[46]:
{'lnode': 'node_2', 'scratch': 'hi', 'count': 4} Look at current stateĀ¶
Get the current state. Note the values which are the AgentState. Note the config and the thread_ts. You will be using those to refer to snapshots below.
InĀ [47]:
Copied!
graph.get_state(thread)
graph.get_state(thread)
Out[47]:
StateSnapshot(values={'lnode': 'node_2', 'scratch': 'hi', 'count': 4}, next=(), config={'configurable': {'thread_id': '1', 'thread_ts': '1ef2eede-6a1c-63f9-8004-353e583a5987'}}, metadata={'source': 'loop', 'step': 4, 'writes': {'Node2': {'count': 1, 'lnode': 'node_2'}}}, created_at='2024-06-20T10:14:38.326255+00:00', parent_config={'configurable': {'thread_id': '1', 'thread_ts': '1ef2eede-6a19-64a0-8003-f450376a5d13'}}) View all the statesnapshots in memory. You can use the displayed count agentstate variable to help track what you see. Notice the most recent snapshots are returned by the iterator first. Also note that there is a handy step variable in the metadata that counts the number of steps in the graph execution. This is a bit detailed - but you can also notice that the parent_config is the config of the previous node. At initial startup, additional states are inserted into memory to create a parent. This is something to check when you branch or time travel below.
Look at state historyĀ¶

Try again with as_nodeĀ¶
When writing using update_state(), you want to define to the graph logic which node should be assumed as the writer. What this does is allow th graph logic to find the node on the graph. After writing the values, the next() value is computed by travesing the graph using the new state. In this case, the state we have was written by Node1. The graph can then compute the next state as being Node2. Note that in some graphs, this may involve going through conditional edges! Let's try this out.
