You will find a new download_images.ipynb in your nbs folder after you git pull. It shows how to download a dataset for training a model of your own. Many thanks to @lesscomfortable for his help on building this.

Note that this requires the latest fastai, just released today. To get it, go to http://course-v3.fast.ai/ , click ‘returning to work’ in the sidebar, and follow the instructions. Generally, they will be somelike like:

  • Click New->Terminal in Jupyter, then type:
  • conda update conda
  • conda install -c fastai fastai


@part1_v3 Note that we have consolidated the forums so there is now just one topic you have to follow to get all official course updates, and one topic per lesson for all official lesson updates. This topic you’re reading now is the topic for lesson 1. Please scroll to the top and read to see that resources available and updates. And here is the topic for the course as a whole:

For each, I suggest that you select Watching from the notification list at the bottom of each of these topics, as shown below. That way, you won’t miss any important announcements. (We won’t be making any further announcements over email.)


Note that after you conda update and git pull, you’ll find that there’s been one change to fastai - ConvLearner is now called create_cnn. You’ll need to make that change in any notebooks that you’ve created too.


There are now 2 sets of course notes kindly created by students - both added to the top post of this thread.
