I'm trying to work with Autosklearn in Google Colab, for which I have done the following steps:

!apt-get install build-essential swig 
!pip install auto-sklearn

I get the following error when I try to

import autosklearn

IncorrectPackageVersionError: found 'scikit-learn' version 0.22.2.post1 but requires scikit-learn version >=0.23.0

I have tried to do the following:

!pip install --upgrade scikit-learn

Requirement already satisfied: threadpoolctl>=2.0.0 in /usr/local/lib/python3.6/dist-packages (from scikit-learn==0.23.2) (2.1.0)

but when I check the sklearn version I see the following:

import sklearn

print('The scikit-learn version is {}.'.format(sklearn.__version__))

The scikit-learn version is 0.22.2.post1.

And I still get the error when I try to import autosklearn

How else can I install /upgrade to scikit-learn version 0.23.2 (current version)?

The issue here is that Colab imports scikit-learn already at startup (version 0.22.2.post1), before you manually install the new version (version 0.23.2). If you restart your runtime after the install, the new version will be used.
