Lesson 1 discussion - beginner


(Tash Robinson) #44

Just started lesson 1. I created an account on Crestle and it says select /courses/fastai2 this folder does not exist. Is it moved or how do I get it to show up? It is mentioned that things have been moving around and all information on the current location is on the website… I’m assuming it meant here in the forums, but seach turned up nothing. Is there somewhere else I should be looking?

Hello.

How many images should I have in train dir to find learning rate by lr_find()? I’m asking, because to distinguish men vs. women ~70 images per each category is kind of enough to train the last layer, but not enough to find learning rate by lr_find(): http://dl3.joxi.net/drive/2018/02/18/0011/4037/757701/01/f6ff6494f9.jpg

Thanks.
