I have tested the klaam/notebook/demo.ipynb file on Google Colab. It raised an error of missing modules.

Error Message:

When I install the missing modules manually using !pip install <module-name> it works well.

I printed the output of the installation in a separate file:

After some search, I wasn't able to solve the problem. I will be thankful if you can advise.
