Course 1, week 3, Assignment --- only 88/100

I did not hard code anything …but only received 88/100

Might there be an error with the grader itself ? Got the following error message:

[ValidateApp | INFO] Validating ‘/home/jovyan/work/submitted/courseraLearner/W3A1/Planar_data_classification_with_one_hidden_layer.ipynb’
[ValidateApp | INFO] Executing notebook with kernel: python3
[ValidateApp | ERROR] Timeout waiting for execute reply (30s).
[ValidateApp | ERROR] Interrupting kernel
Tests failed on 1 cell(s)! These tests could be hidden. Please check your submission.

You are not allowed to modify cells anywhere else than were told to add your solution. Are you sure you haven’t changed the structure of the notebook?

Please follow How to Get a Clean Copy of an Assignment Notebook and add only your solution where asked for.

ok, sometimes I added my code not exactly between ‘Your Code Starts here’ and ‘Your Code ends here’ …

Will check it out later.

Thx for the very quick response!

There are also some unfortunate behaviors of the grader where it detects an error but for some reason cannot tell you which function is incorrect. We have complained many times to the course staff about this, but it is apparently a limitation of the underlying Coursera platform and not so easy to circumvent.

One thing to check is that you have the latest version of the notebook. Check the template code for initialize_parameters: there should be no setting of the random seed in that logic. If you even see it as a comment, then you don’t have the latest version. Or if you modified the code to add back the setting of the seed that might cause this error.

If you can’t find the error, then we may need see your code (by private conversation).
