It sounds like most of the tests are failing on your code. Are you sure that all the tests pass when you run the code in the notebook? Notice that there’s a cell that fails when you try to use basic_sigmoid with a vector input. You need to comment out that line, so that the execution doesn’t stop there. Then do:

1. Kernel → Restart and Clear Output
2. Save
3. Cell → Run All

Then page carefully through the notebook and check the output of all the test cells. Do any of them fail?

Be sure you have not re-named your notebook file. The grader only uses the original file name.

[Joshua_Mawutor_Agban]

This has been my output throughout the exercise.
I don’t know where the error is coming from.

[Joshua_Mawutor_Agban]

This is the name of the file, am I wrong?

[TMosh]

That is the correct file name.

Have you completed all of the parts of the assignment? You cannot grade a partially-completed notebook.

[Joshua_Mawutor_Agban]

Yes. I have completed the assignment

[Joshua_Mawutor_Agban]

This is what I had. but I have passed all the test in the various cells

For those who find this thread later:

The issue was the use of a hard-coded value in the sigmoid() function.
