Practice model recommending e-commerce products to users

Hello,
I was just running the additional practice model "Recommending e-commerce products to users" in the AI4I Basics.
After this is added the "Evaluate Recommender" module to the training experiment to see how good the scores would be.
Unfortunately  get an error message saying the test data contains invalid data. I just connected it the same way as the movie recommender experiment.

Any idea why that happens?

Cheers,

Gags

Hey @gags.

The "Evaluate Recommender" module needs to be connected to the test data (from Split Data) on the left input and the scored data (from Score Matchbox Recommender) on the right input. I've shown it in the image above.

Hello Yi Sheng,
Thanks for your response.
Yes, that's exactly how I connected the Evaluate model also and I get the Error 0018 as mentioned. Test dataset contains invalid data. I have not modified anything else in the datasets or modules.

Hm. Did you get this error before or after running the workflow? ie. did this appear before you even ran the actual workflow? I'm trying to see how I can replicate your issue.
