C5 W3 A2 - Trigger Word detection

I got the following error after my submission of trigger word detection programming assignment.
“Cell #24. Can’t compile the student’s code. Error: FileNotFoundError(2, ‘No such file or directory’)”.
I don’t know how to handle this. Can anyone help

I believe there is an error in your thread title - the Trigger assignment is in Course 5, you listed C4.
I have edited the title.

Did you delete any of the files from the assignment, or have you re-named the notebook file?

Also, check whether you have modified the line of code that exports the “train.wav” file.

Sorry sir, that’s Course 5 only. I mistakenly typed course 4.

Thank you sir. Now has been submitted.

Previously I slightly modified the code sir. Now it is fine sir. Thanks sir.
