How to solve the error when my all the code test are passed, but when I submit, in the grade section it throws error.

Course Q&A Deep Learning Specialization Convolutional Neural Networks
1

I have enrolled in Deep Learning course by Andrew Ng. In Convolutional Neural Network course in week 2. I have passed all the tests in the lab notebook but when I submit it, in the grade section it gives an error and I am unable to submit it. In the grader output it shows error:

Cell [#UNQ_C2](javascript:void(0);). Can’t compile the student’s code. Error: SyntaxError(“unmatched ‘)’”, (‘/tmp/student_solution_cells/cell_16.py’, 40, 5, ’ )'))

Traceback (most recent call last):

File “/home/www/app/grading/exceptions.py”, line 112, in handle_solution_errors

yield {}

File “/home/www/app/grading/abstract.py”, line 393, in _grade

SyntaxError: unmatched ‘)’

But there is no parenthesis error in the code. And even while running the code it isn’t throwing any error.

Hi @Garv.it

Please take a look at these similar posts:

If your problem remains unsolved, you can share your notebook with me, so we can look for possible issues together!

Hope it helps!

Something in your notebook has broken the grader. Likely it has been modified in an unintended manner. For example, using a different platform to modify the notebook, deleting or adding cells, modifying the notebook metadata, etc.

I recommend you delete your notebook and get a fresh copy and start over. That’s the simplest way to proceed. Debugging grader issues is very difficult.

Does anyone know how to solve this problem?
I’ve tried resetting the kernels, downloading a copy and reloading it and nothing. And I don’t know what else to try

@MG03000, what is the detailed feedback you get from the grader? Please post a screen capture image.

Hi @TMosh!!, I have already solved the problem, it turns out that I had a part of the alpaca model function wrong, but the grader was passing the tests.
Thank you very much for your attention and help
Best regards

Can you forward me an image that shows the part of the code that was wrong? I’d like to improve the tests to catch whatever the error was.

[/quote] Hi @TMosh sorry for the delay in replying to the message, I hadn’t seen it. I can’t send you the exact screenshot of the error but I can send you the part of the code that produced it, which is the following:

GRADED FUNCTION: data_augmenter

def data_augmenter():
‘’’
Create a Sequential model composed of 2 layers for data augmentation:
- Random horizontal flipping
- Random rotation
Returns:
tf.keras.Sequential
‘’’
data_augmentation = tf.keras.Sequential([
RandomFlip(‘horizontal’), # Flip images horizontally
RandomRotation(0.2) # Randomly rotate images by 20%
])

return data_augmentation

I hope you find it helpful,
best regards and
happy new year.
