Can anyone who can pass this section let me know what’s wrong with my output for sampling decode? Can’t pass any test case. ![Screen Shot 2021-11-08 at 9.45.10 PM](https://global.discourse-cdn.com/dlai/original/2X/0/0bb88b2139de74f6f49c3020a3a74b0d428fdc43.png) ---

Hi @sylviasc, Can you share your lab ID with me ? In the assignment, when you click the top right “Help” button, a panel will open and your lab ID will be shown at the bottom. I shall take a look. When you reply back, kindly tag me in the post so that I’m notified. Thanks, Mubsi ---

Hi @Mubsi, thanks for following up. I have solved this issue by reverting to the original parameters about a couple of functions that I thought having way too many parameters (as mentioned in another thread I posted here). I do hope you can look at the last part of my assignment though. I have this “TypeError: iteration over a 0-d array” error couldn’t resolve. My lab id is cyniiqjq. Thanks! ---

Hi @ivanpoon, Your exercise till Ex 7 seems correct a glance. It might be possible that something in the notebook changed which should not have had. I’d recommend to try to get a fresh copy of the notebook and just copy/pst your solutions in it, and try again. Let me know how it goes. Best, Mubsi ---

After restart from a fresh copy. It works. It seems it is a good Standard Operating Procedure if all checked but still failed, as the grader is not perfect.
