How do I check which versions of packages I'm using in GoogleColab?

Some are preinstalled in Colab and some installed with !pip install module_name in Colab cell.

First you have to import the module, then run this command:

name_of_module.__version__

For example:

import nltk
import tensorflow as tf
nltk.__version__
# '3.2.5'
tf.__version__
# '2.6.0'
