Lesson 1 - What's your pet

Welcome to lesson 1! For those of you who are using a Jupyter Notebook for the first time, you can learn about this useful tool in a tutorial we prepared specially for you; click File->Open now and click 00_notebook_tutorial.ipynb.

In this lesson we will build our first image classifier from scratch, and see if we can achieve world-class results. Let's dive in!

Every notebook starts with the following line; it ensures that any charts or images displayed are shown in this notebook.

%matplotlib inline

We import all the necessary packages. We are going to work with the fastai V2 library which sits on top of Pytorch 1.3. The fastai library provides many useful functions that enable us to quickly and easily build neural networks and train our models. For now fastai v2 is in a separate package called fastai, butonce it's fully ready to be released, it will just be called fastai.
