I’m running into an assertion error that prevents me from completing this assignment:

**AssertionError Traceback (most recent call last)**  
 **in**   
\*\* 6 expected\_values = [0.2850931567761623, 1.1890913024229996e-07]\*\*  
\*\* 7 assert not(type(difference) == np.ndarray), “You are not using np.linalg.norm for numerator or denominator”\*\*  
**----\> 8 assert np.any(np.isclose(difference, expected\_values)), “Wrong value. It is not one of the expected values”**

**AssertionError: Wrong value. It is not one of the expected values**

However, I’ve been looking at this error for a long time now and I still can’t figure what is going wrong. Nothing in my code suggests that I’ve made a miscalculation.

Thank you but I was able to figure it out!
