Hi,
I am the ‘all tests passed’ for this exercise and I can build and validify the model toward the end of the assignment. But I notice that I am not receiving the grade for this exercise. Would you mind helping me with this problem?

With looking at your image, it looks like you hard-coded “n_classes” to 23. This should be a problem since a grader may change the value for “n_classes”. Even if this is not the case, it is better for you to check any hard-coded variables exist or not…
