So i have manage package that has been tested and riched 80%. But when we moved it to new org and done test we saw only 50%. What is more big test class ( 290 lines ) was included in to test coverage with 0% of cover. Did any one have same issue. How to make it excluded from test? No other test class is there just this one. It is begining with @isTest

I am stuck at the Create and Train the Dataset step on the Build a Cat Rescue App That Recognizes Cat Breeds Trailhead module.

I have successfully created the lightning component, uploaded the zip file and clicked on the train button but when I try to Verifiy I get the following error message:
"Challenge Not yet complete... here's what's wrong: 
Could not find a successful cat dataset training. The training may take a couple of minutes after the model is created."

Could you please advise ?

Thanks for your help.
