NP ALL CLOSE
Let me show you a great way to compare and test outputs and code
I like to use np.allclose
In Ipython we can see some of the parameters of this function
It takes in two things to compare, and you can set different tolerances. Also there is a parameter for how you want to deal with NAN or not a numbers
So for an example these will obviously return false because they are different
But let’s do something a bit harder. We will do 1 and a bunch of .9999s. This will return True since your computer cannot tell the difference, but we won’t get into details of why that is here.
So there you have it, that is how you use np.allclose in python
