Issue with section 3.2

[edwardmiles92]

I have some issue to follow the instruction in this video

In the instruction at 3.2.1 GDP training set
I check in the global data products, I already saw the trainining_set

So I move to the next step
Sklearn training GDP
when I try to run the pipeline, it just have this error

What is wrong with the issue?

I think the video is working on unit 2, but the data preparation pipeline is under unit 3. I think we need to create a new "training set" under the project unit 2
