Hello,
A minor issue upon setting up fastbook on colab, I am getting below error
ERROR: pip's dependency resolver does not currently take into account all the packages that are installed. This behaviour is the source of the following dependency conflicts.
google-colab 1.0.0 requires tornado~=5.1.0; python_version >= "3.0", but you have tornado 6.1 which is incompatible.

note: It is not a major blocker can be mitigated by adding
!pip install tornado==5.1
