This code cell is already provided so I think it’s fine if I put it here.  
Where is the multivariate\_gaussian function coming from? It is not coded anywhere above, nor is it imported. And what is its code?

Hello @Manav_Garg,

![image](https://global.discourse-cdn.com/dlai/original/3X/0/e/0ea86e7a49608b0d53a32bb92bf9414425c44c17.png)

This line will import everything defined in `utils.py`, including `multivariate_gaussian`.

Cheers,
