2 conflicting grader-required-cell's

[smarti]

I have 2 grader required cells with different code to be run - both are locked, both run on submit, so I cannot pass the submit tests. Which is correct?

Looking for navigation so that I can reset to only the correct #grader-required-cells, or maybe there is an update? Thank you.

grader-required-cell

hist = train_happy_sad_model()

grader-required-cell

hist = train_happy_sad_model(gen)

This is the correct one:
hist = train_happy_sad_model(gen)
Here’s how to refresh the workspace
