23.03.2020 · You only want to save the weights and load them up later. You can do that with learner.save and learner.load on an already instantiated learner instance. You want to save and load the full learner with everything you had. Then you do learner.export then learner = load_learner. 9 Likes ingbiodanielh (Danielh Carranza) February 9, 2019, 11:44pm #3

Jan 30, 2019 · To create the Learner for inference, you’ll need to use the load_learner function. Note that you don’t have to specify anything: it remembers the classes, the transforms you used or the normalization in the data, the model, its weigths… The only argument needed is the folder where the ‘export.pkl’ file is.
