05.01.2021 · Here the predict class for our image is '3', which corresponds to a label of 0. The probabilities the model found for each class are 0.65 and 0.35 respectively, so its confidence is pretty high. Note that if you want to load your trained model and use it on inference mode with the previous function, you should export your Learner.

This function is almost the exact same as fastai 's. ... Learner.predict ( x : Learner , item , with_input = False , rm_type_tfms = None ) ...

In fastai, you can now export and load a learner to do prediction on the test set without having to load a non empty training and validation set.

Jan 05, 2021 · vision.learner is the module that defines the cnn_learner method, to easily get a model suitable for transfer learning. Transfer learning ¶ Transfer learning is a technique where you use a model trained on a very large dataset (usually ImageNet in computer vision) and then adapt it to your own dataset.
