Difference between fit_one_cycle and fit

I’m sorry if this is question has a blindingly obvious answer, however I was not able to find it anywhere in the forum or even in the videos.

What’s the difference between fit_one_cycle and fit?

See here:

But essentially fit is a very basic training loop, whereas fit one cycle uses the one cycle policy callback

are you here now ? i think fit can use more cycle ,but now fit_one_cycle can do some thing better in somewhere,you can learn which is better in this paper : [Super-Convergence: Very Fast Training of Neural Networks Using Large Learning Rates] https://arxiv.org/pdf/1708.07120,perhaps it will help you
