Trying to work through the fastai course with Google Colab, but I am getting a dependency error in the first section of the Intro notebook, where I am installing the fastbook library with pip as follows:
!pip install -Uqq fastbook
import fastbook
fastbook.setup_book()
Running the above pip is producing the following errors:
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.

I am unable to proceed with any of the subsequent code in the notebook because of this initial installation error.
Any idea how to resolve this?
