Lr_find Description Launch a mock training to find a good learning rate, return lr_min, lr_steep if 'suggestions' is TRUE Usage lr_find( object, start_lr = 1e-07, end_lr = 10, num_it = 100, stop_div = TRUE, ) Arguments v1 of the fastai library. Plotting the loss function agains With LR Finder When attached to the trainer, this handler follows the same procedure used by fastai. We’ll set up a Learner as usual: using FastAI The lr finder should not disturb the weights initialization, hence the lr finder callback should first save the model parameters to a local file before it starts and should reload it back at end. The author uses fastai's learn.
