-###### Common training use cases 
-- 16-bit mixed precision
-- Accumulate gradients
-- Check val many times during 1 training epoch
-- Check GPU usage
-- Check validation every n epochs
-- Check which gradients are nan
-- Inspect gradient norms
-- Learning rate annealing
-- Make model overfit on subset of data
-- Min, max epochs
-- Multiple optimizers (like GANs)
-- Run a sanity check of model val and tng step
-- Set how much of the tng, val, test sets to check (1-100%)
