Hello @ARNAV_BATRA ,

Thanks for reaching out.
I guess you forgot to replace the “None” with appropriate parameters/values or you forgot to save your file before submitting.
This error comes when the appropriate value is not passed and the grader reads “None”.

Nevertheless, I would like to see your notebook to give you a specific answer for your specific problem.So can you kindly send your notebook via message. Click on my name, you will get an option for message.

With regards,
