Hi @edgarbc, 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 ---

> [@edgarbc](#): > > aqvowduz Hi @edgarbc, In your `Ex 1`, when calculating the categorical values of `y` you were hardcoding the value of number of classes. As a rule, remember, _ **unless specifically asked to do so** _, never use hardcoded or global values in the graded functions. You can take a look at your `Ex 1` for more information, it runs successfully now. Best, Mubsi ---

Hello @Mubsi, I am also stuck with my UNQ\_C1 def\_get\_sub\_volume exercise - even after reading the forum and discourse posts - and was hoping you could help me as well. The test cell is showing me: […] Error: Wrong shape. for variable 1. Error: Wrong output. for variable in position 1. […] 1 Tests passed 2 Tests failed I presume the error is somewhere in the one-hot encoding but I can’t figure it out. My labID is : dqfvmaab Thanks for your help! It’s much appreciated 🙂 Christian ---

I think I could resolve the issue. I hadn’t specified the num\_classes parameter when applying the keras.utils.to\_categorical method to y in order to one-hot-encode the label array y. After defining the num\_classes parameter by setting it equal to the num\_classes variable that is input to the def\_get\_sub\_volume, the test cell showed the expected output without any error messages. Hope this helps someone. ---

Hi @Mubsi , Lab ID gzghtoqn I am stuck with errors for quite a while now. My course deadline is tonight so any help is appreciated. Error: Wrong output. for variable in position 0. Error: Wrong output. for variable in position 1. The surprising bit is that the next section displays the expected MRI image accurately. So, I’m not sure what I’m missing. Thank you! ---

Hi @Mubsi , Thanks for getting back. The issue was just the +1 was missing in the array slicing. Yep, passed the course and received the certificate. 🙂 Amrita ---
