Incorrect gradings / Week1/Programming Assignment: Convolutional Model, Step by Step

I finished the required first half of the notebook with success and left the second half part, which is optional, undone at the momonet. However, I only got 50/100.
Here is the error:
[ValidateApp | INFO] Validating ‘/home/jovyan/work/submitted/courseraLearner/W1A1/Convolution_model_Step_by_Step_v1.ipynb’
[ValidateApp | INFO] Executing notebook with kernel: python3

Hello @Li_Qingwei!

You posted this in the General Discussions but it belongs to the DLS Course 4, right? Please move it to the relevant course category as described here.

Regarding your query, it says, “Tests failed on 2 cell(s)”. Clicking on the “Show grader output” will tell you which tests are you failing. Can you share the full error, or this is the full error?


Sorry for that. I am new joining this community and am not quite familiar with how it works. I Will try moving my question to DLS Course 4.

And yeah that’s all the error I got.

Please send me your notebook in ipynb format in a private message. Click my name and message.

You are not passing all the graded tests. Before submitting your assignment, it is necessary to pass all the tests.

You are failing the conv_forward test. Your vert_start, vert_end, horiz_start, and horiz_end are wrong. You missed the stride factor. Also, your implementation of a_slice_prev is incorrect. Loop over i, then use vert_start, vert_end, horiz_start, horiz_end. Maybe this guide will help you.


Thank you very much for your feedback. I changed my code and passed the test!

I am glad you did it…
