Hi! I have an “error” when running Lesson 2’s code.
I’ve copy and pasted the code into a new document and everything is fine except when I run the code to find the learning rate.
I run: learn.lr_find() and I get: 
It’s just a bunch of #na#'s
The graph looks normal: 
Is there something wrong with the code? Everything seems to be working fine except for the #na# part.
Thanks!
