22.06.2020 · For the latest version, you should use a Callback with fit method: learn.fit_one_cycle (10, slice (5e-3,5e-2),cbs= [ShowGraphCallback ()]) Here is the document. The benefit of using this new callback for plot the train validation metrics is it happens directly after each epoch of training and validation, no need for a separated line of code.

Single Run. The callback automatically logs metrics, hyperparameters like learning rate and momentum, histograms of gradients and parameters and prediction ...

Nov 29, 2021 · By default, metrics are computed on the validation set only, although that can be changed by adjusting train_metrics and valid_metrics. beta is the weight used to compute the exponentially weighted average of the losses (which gives the smooth_loss attribute to Learner). The logger attribute of a Learner determines what happens to those metrics ...

Jan 05, 2021 · Metrics for training fastai models are simply functions that take input and target tensors, and return some metric of interest for training. You can write your own metrics by defining a function of that type, and passing it to Learner in the metrics parameter, or use one of the following pre-defined functions.
