FastAI Versions to Years?


As of, August 24, 2020, I find the links:
2018, correct?
Year: 2019

As mentioned at:

“This web site covers the book and the 2020 version of the course,”
Year: 2020

Although, at

There is no 2020 version of part 2 of the course recorded yet, and
we don’t have a date for when that might happen

I’m assuming that each year is a different version of FastAI.
Correct or not?

For each year, what is the version of FastAI?


2018 (Part 1 and 2) --> fastai 0.7
2019 (Part 1 and 2) --> fastai 1
2020 (Part 1) --> fastai 2



I’ve created at least 3 posts so far to ask questions.

Haha no worries… Let me know if you have any other questions!

Please see my other post, which expands on the version issue:

Further on this subject

I’m also seeing “V3” on the webpages.
And “V1”, “V2”

I’m assuming that this refers to the
fastai “course”



v1 of the fastai library. v2 is the current version. v1 is still supported for bug fixes, but will not receive new features

Has link:

Welcome to fastai
**NB: these docs are for v1 of the fastai library. v2 is the current version.
(obviously, outdated, and the docs not updated)

Temporary home for fastai v2 while it’s being developed

This is the old home of fastai v2. The new home is fastai/fastai.

(full link not typed in)

v1 and v2 are the fastai library versions (as mentioned above). v3 is the version of the course. So let me update my previous comment:

Course v2 - 2018 (Part 1 and 2) --> fastai v0.7
Course v3 - 2019 (Part 1 and 2) --> fastai v1
Course v4 - 2020 (Part 1) --> fastai v2

Course v1 is from 2017 and used Keras IIRC.

Is that clearer?


Yes, thanks!
