Hi @Diana_Pavlenok,
Your Ex 4 fails:
Of course, if you are not passing the tests in the notebook, your autograder is going to fail as well.
Make sure you pass all the unit tests for all of the exercises before submitting to the autograder.

Also, you are getting this error because you are not using the Trax functions. You are supposed to be working with Trax functions.
In this case, you have to use trax.fastmath.random.normal
Hello @Mubsi
Thank you very much for the hint.
I corrected the function, but, sadly, it still doesn’t allow me to submit this exercise to the autograder. 
Is there maybe an option to somehow pass this exercise and get graded without it?
Hi @Diana_Pavlenok,
What do you mean by that ? Can you share the screenshot of the error for your failed submission ?
And no, there’s no such option. The only way to pass is to submit and get the minimum passing grade.
Best,
Mubsi
@Mubsi Sure,
Here is the screenshot:

What do you mean by that ?
[/quote] I mean that the autograder still fails when submitting the assignment.
Hi @Diana_Pavlenok,
So you are able to submit your assignment, you are just running into an error by the grader.
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 Error: Grader feedback 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 Error: Grader feedback not found.
Please make sure you are not doing any of these listed things.
Best,
Mubsi
Hi @Mubsi,
I just made a fresh copy of the notebook and filled them in with the same all code once again. This time I am getting a different error: syntax error (you can see it on the screenshot).
Yes, I understand the AutoGrader submission rules, but just can’t see where exactly I’m violating them. As I wrote earlier, I checked the exercices for global variables and extra code cells, but can’t see any at the moment, and thus have a feeling of being stuck.
Could you please give me a more specific hint about what I’m doing wrong this time (even if it’s really obvious)?
Best,
Diana
Hi @Diana_Pavlenok,
This is because your notebook has a syntax error in Ex 2:
Please make sure your notebook runs successfully, passes all the tests before submitting to the grader.
Best,
Mubsi
Later when you’ll fix the syntax error, your Ex 5 will fail because you passing n_units = None
Later your Ex 6 fails.
My guess is you didn’t even run the assignment before submitting, otherwise you would have seen all these error.
