Hi @sgugger,
I’m a little confused about the versions of the course. I just started following along with “fastai course v-3”. You are mentioning that version 2 is the newest course, and people in slack are talking about a version 4 that they are currently working on right now… We even had a meeting to present our homework from lesson 2, and I was definitely not working on the same lesson 2 they were…
Would you mind clearing up my confusion ?
If you did not register with USF about following the last version of the course (v4) you do not have access to the private forums and lectures (they will all be public when the MOOC is released in July).
It seems your confusion is due to the difference in course versions and library versions.
There is the fastai v2 library which is a newer version of the fastai library. Note that fastai v1 was used in course v3, but now fastai v2 is used in course v4. As Sylvain mentioned, course v4 is being offered to USF students, while the MOOC version will be released in July.
Does that clarify things?
Absolutely, thank you very much! 
What is USF ? Can we register for USF student now or is it too late?
USF is the University of San Francisco, which is the university the course is hosted at.
The course is already over (finished on Tuesday). You will have to wait for the online release in July. In the meantime, you can check the older version of the course at https://course.fast.ai
The older version is very similar, just that the library is somewhat different, but most of the concepts are the same.
Hello @sgugger:
Could you kindly let us know when will be the tutorial video for Course_4 available for public
Around July, the course got over last Tuesday and will be made public in a couple of months!
Where will it be broadcast online? in Youtube?
It will be similar to how the previous courses were (like v3), so they’ll all be uploaded to his youtube channel presumably all at once
Can anyone tell me whether the FastAI course v4 part 2 will be based on Foundations of deep learning like that in v3 or it’s gonna teach us concepts similar to part 2 of the previous courses?
We do not know yet. Jeremy said that we’ll go entirely through the book before going to other topics and see from there. He’s mentioned wanting to bring back certain subjects like object detection etc but it’s unknown if this will be in part 2 or a separate course similar to the NLP.
Which code walkthroughs?
Very fair question 
Jeremy did some source code walkthroughs a few months back that are excellent. Some parts have changed slightly (very slightly) but they’re a great resource for understanding the internals.
+1 when is course releasing.?
Maybe tomorrow? 
I’m just getting going on v3 and can always come back. Can’t wait!
Don’t know if other people have seen this but there is a duplicate thread and Jeremy has said it will only be a week or two FastAI course v4 MOOC
i think they are trying to synchronize the official release of fastai2 and v4 version of the course. Maybe that is the reason for the delay.
Cant wait to look at V4 Excited!
