TF-AT Course 1, Week 1 - Assignment 1

Course Q&A TensorFlow: Advanced Techniques Specialization Custom Models, Layers and Loss Functions with TF
1

I am having problems with the grader for the week 1 programming assignment.

I have passed all tests in the notebook however I am failing the grader submission with a score of 4 out of 10.

It’s saying: “Tests failed on 6 cell(s)! These tests could be hidden.”

What does it mean by tests could be hidden.

Could this be the issue? Any thoughts?

many thanks

From the errors you have many variable names that are not defined it says. Are you using them as strings in quotes rather than just plain variables?

The hidden tests are for scoring purpose and not shown to learners. In your case, the missing variables such as red_df, which could be in a different name, should be defined and passed in the test function as input.
