New:
- **cycle\_momentum** argument for bothautofit and fit_onecycle method that will cycle momentum between 0.95 and 0.85 as described in [this paper](https://arxiv.org/abs/1803.09820)
- Learner.plot method that will plot training-validation loss, LR schedule, or momentum schedule
- added set_weight_decay and get_weight_decay methods to get/set "global" weight decay in Keras
Changed:
- vision.data.preview_data_aug now displays images in rows by default
- added multigpu flag to core.get_learner with comment that it is only supported byvision.model.image_classifier
- added he_normal initialization to FastText model
Fixed:
- Bug in vision.data.images_from_fname that prevented relative paths for directory argument
- Bug in utils.y_from_data that returned incorrect information for array-based training/validation data
- Bug in core.autofit with callback failure when validation data is not set
- Bug in core.autofit and core.fit_onecycle with learning rate setting at end of cycle
