How do you save a training-validation loss plot?

I’ve created a learner and I’m training it using fit_one_cycle. I’ve set a callback to display the training and validation loss as the epochs progress. How do I save the plot generated as a .png say?

cbs = [ShowGraphCallback()]
learner.fit_one_cycle(n_epoch = epochs, lr_max = lrs, cbs=cbs)
