Trying to complete the 'Create Models using Bigquery ML: Challenge Lab' but getting very mixed scoring from the progress checks.
For instance, task 2 requires to evaluate the model using ROC on unseen data. I've done that but kept getting the error that it's not completed (more on this later).
So I proceed to the rest of the tasks (getting 0 for the rest). Last task requires you to run a prediction using the model. I ran the evaluate method instead, yet the assessment completed for this task when it shouldn't have.
I executed the progress checks again, now task 2 is suddenly completed while task 3 is stuck at 15/25.
Bit puzzled with what's going on, could use some help please. Thanks!
Wait for sometimes or do the same process again.There Might be a maintanace going on or might be the lab having problems . Not sure about it.
( if you perform the lab using any scripts to complete the lab) Perform the lab manually.
Hello. I run into the exact same issue. Task 2 checkbox says "Confirm that both machine learning models have been evaluated" (see image bellow) which is clearly beyond the scope of the task and actually corresponds to Task 3. So only when you complete Task 3 will the checkbox for Task 2 be marked as completed. This is clearly a bug.
The next issue is that even if you complete Task 3 the checkbox will not be marked as completed (even if you managed to complete Task 4):
This is indeed a buggy lab and it has got many negative reviews. I hope we have a solution soon.
Hi Farid,
Thanks for confirming that there is indeed a bug. I'll raise this to the Qwiklab support.

Hi friend,
I tried a few times, and it finally worked.
1) Switch to chrome browser for everything.
2) For your EVALUATE code, do not use tilda ` around the model. Example:
ML.EVALUATE(MODEL ecommerce.customer_classification_model, ...
Quiklabs asked for a full video recording of the lab attempt, so I didn't follow up with them.
Hope this helps.
I have tried this, but I am still stuck.
