Lesson 1 discussion - beginner

So now that the model is trained on dogs and cats, how do I input a new image, and then let the model tell the accuracy for dog or cat? I guess normally you would write an application around it? For now, to be simple, could that be done inside Jupyter notebook?

What is the equivalent of below line in fastai 1.0?

tfms = tfms_from_model(arch, sz, aug_tfms=transforms_side_on, max_zoom=1.1)

I see there is get_transforms() but that does not include model architecture to take statistical transforms from??? Kindly help.
