C5 week 1 autograder says music_inference_model is incorrect

Autograder says music_inference_model is incorrect, but everything worked fine on the notebook.

Code Cell UNQ_C1: Function ‘djmodel’ is correct.
Code Cell UNQ_C2: Function ‘music_inference_model’ is incorrect. Check implementation.
Code Cell UNQ_C3: Function ‘predict_and_sample’ is correct.
If you see many functions being marked as incorrect, try to trace back your steps & identify if there is an incorrect function that is being used in other steps.
This dependency may be the cause of the errors.
