Please use this topic to ask any question about the course (even if you think they are stupid, we really love stupid questions). Note that this is the beginners topic, so if you have already followed the course and your question/intervention is more advanced, please use the non-beginner discussion topic.

Questions with lots of likes will be asked live by John. If you see a question you’d really like to be answered, click on the heart under it to like it. Don’t post duplicate questions if possible. They will be removed by the moderators (don’t be mad if this happens to you, it’s nothing personal). If your question is not answered during the course, it will be answered on this topic after the lesson.

This topic will be very crowded, so please refrain from getting too much off track (create another topic for this) and please like the post of someone who replied to you instead of replying with thank you.


  • Remember that the book has a chapter containing details on each lesson

Hi Jeremy,

I think the non-beginner topic wasn’t created so I made one and updated the wiki-I hope that’s okay :smiley:


A bit of OT question: is it okay if we snapshot an image of the class at some point for a social media post? Given that it’s not yet public yet, I wasn’t sure

To anyone that might feel a bit uncomfortable with the top down learning methods:

I had written extensively about my struggles in “How not to do fastai”, I cover my pains of someone who studied in university-of how difficulty it was to learn something in top down fashion :smiley:

We had also shared this in a “reverse” interview where Jeremy kindly interviewed me. I hope this helps :pray:


The questionnaire is in the book. Check the fastbook repo notebooks for the Jupyter notebook versions of the book.

Here is the chapter for lesson 1:


Yes, Jeremy said the forum was overloaded at the start of the lecture.

Thanks for your introduction. I saw both ‘bird.png’ and ‘bird.jpg’ in the presentation earlier. Just wanted to point it out.

Is there somewhere I can get more info on the project which used recurrence plots as input to DL? (mentioned by Jeremy in the lecture just now; I missed if there was a reference)
