got stuck in programming exercise

hi all,

I have tried out this neural network:

https://github.com/amarsic1990/Deep-learning/blob/master/Logistic%20Regression%20with%20a%20Neural%20Network%20mindset.py

but I realized the shape of X is a 2 by 3 matrix. Why is that?

Hi @thomas1989752252! Your post was originally in the “GitHub Learning Lab” forum. I’ve moved it to the Programming Help and Discussion forum, so that you may hopefully get more responses.
