fastai.datasets contains a set of curated datasets that sits on S3. ... the main way to represent and hold training and test datasets. fastai.vision.data.

In this dataset, we have train, validation, and test sets as is common in machine learning datasets. Here I'm using get_image_files to read ...

If I run val_preds,val_targets = learn.get_preds() I get the predictions and targets for the validation set. How do I run it for the test ...

08.02.2020 · @sariabod-For test test prediction we have to create new data using databunch and instead of valid we have replace Test folder in the argument.then learn.data=new data ,finally we can make prediction on that using your code.This was suggested in this Forum .But Still Its not working .Prediction for test class labels is not supported directly in fastai.
