"Our images are all different sizes, and this is a problem for deep learning: we don't feed the model one image at a time but several (what we call a *mini-batch*) of them. To group them in a big array (usually called *tensor*) that is going to go through our model, they all need to be of the same size. So we need to add a transform twhich will resize these images to the same size. *item transforms* are pieces of code which run on each individual item, whether it be an image, category, or so forth. fastai includes many predefined transforms; we will use the `Resize` transform here.\n", "Our images are all different sizes, and this is a problem for deep learning: we don't feed the model one image at a time but several (what we call a *mini-batch*) of them.

"This command has given us a `DataBlock` object. This is like a *template* for creating a `DataLoaders`. We still need to tell fastai the actual source of our data — in this case, the path where the images can be found." "This command has given us a `DataBlock` object.
