Grade Error for Submitting C3_W1_Assignment

Hi guys
After about 48 hours and many attempts, I see that every exercise is in “Grading failed” state.
Could you help me please?
All the tests are passed…

This is the Error:

Grader Error: Grader feedback not found

Hi @Reza_Jafari83,

At the start of the notebook there’s:

**Important Note on Submission to the AutoGrader**

Before submitting your assignment to the AutoGrader, please make sure you are not doing the following:

1. You have not added any extra print statement(s) in the assignment.
2. You have not added any extra code cell(s) in the assignment.
3. You have not changed any of the function parameters.
4. You are not using any global variables inside your graded exercises. Unless specifically instructed to do so, please refrain from it and use the local variables instead.
5. You are not changing the assignment code where it is not required, like creating extra variables.

If you do any of the following, you will get something like, Grader not found (or similarly unexpected) error upon submitting your assignment. Before asking for help/debugging the errors in your assignment, check for these first. If this is the case, and you don't remember the changes you have made, you can get a fresh copy of the assignment by following these instructions.

This clearly mentions if you do any of the listed things you will run into Grader not found error.

Please make sure you are not doing any of these listed things.

To check my mistakes i need the raw file of C3_W1_Assignment.
Can i ask you to send me that please?

Hi @Reza_Jafari83,

You can get it by following these instructions: Coursera | Online Courses & Credentials From Top Educators. Join for Free | Coursera

In your case, however, I’d mention, first rename your current version to something else, follow the instructions to get the fresh copy and then rename the latest version to something else and your current version back to its default name, which I believe is C3_W1_Assignment.ipynb


Thank you so much.
I solved every problem.
