import langgraph.prebuilt could not be resolved in version 0.3

[muni-wobo]

Hi,
I am using langgraph, today upgraded to Version 0.3
I use prebuild ToolNode using:

from langgraph.prebuilt import ToolNode

Now I see the problem there is no langgraph.prebuilt package?. Did the ToolNode moved to other sub directory?.
I need some quick solution please.

[vbarda]

please update to 0.3.1 -- we split out langgraph.prebuilt into a separate library, and it is now bundled with langgraph as of 0.3.1. after installing 0.3.1 all of the imports should work the same as before

see full release notes here https://github.com/langchain-ai/langgraph/releases/tag/0.3.1

[GoogTech]

Please Don't degrade the version. The best answer is shown below. It worked for everybody, thx a lot @sunilmurali

pip install --upgrade --force-reinstall langgraph

[us]

whats for ToolInvocation? is there any changes on functionalities?

I wish you had written a proper document. Its version updates dude and how many people are using that, you should be act responsible!

[vbarda]

try in a fresh virtualenv

[Kaiohz]

[pt-kunal-mishra]

While prebuilt can be found when running locally, I couldn't find it in the container created below.
There was no problem with previous versions.
If anyone understands the issue with my code, I would appreciate your feedback.

[sahil0094]

Great, thanks

[Mubeen-creator]

no the actuall issue is that the ToolExecutor has been replaced by the ToolNode use this

[sahil0094]

I thought we were talking about ToolNode, no one is talking about ToolExecutor, am I missing something?
