Hi, Mho.

Notice that you posted this under DLS Course 3 - Structuring Machine Learning Projects, but that is not a programming course. There are only quizzes, no programming assignments in DLS C3. I’m guessing that you are asking about one of the LLM based courses. It would help get the thread noticed by the mentors for those courses if you change the category to the appropriate specialization and/or course. You can use the little “edit pencil” on the title to move it.

Sorry, I am familiar with DLS, but can’t help with langchain related issues.

Regards,
Paul

Thanks Paul, sorry about that. I fixed the categorization. Maybe when I grow up I can contribute an AI to auto-categorize these posts.

Hi @Mho_Salim,

  1. What is the name of the lab that you are getting this error in ?
  2. Are you running the lab on the platform or running it locally ?

Best,

Hi, I have the same error.

  1. The lab is “L6-Agents”.
  2. It happens running it locally, on the platform didn’t throw errors.

Could be some version issues?

Hello @Mobsi
The Lab is L6-Agents and I am running it locally. same as @rafanegrette.
It works when I did a %pip install langchain_experimental . maybe this moved after they generated that tutorial.

Best
Mho
