Book Structure

Please note that the code repository is still under development and review.

All the notebooks will be crystalized in the coming months. 

The notebooks have been tested on an ubuntu machine running python 3.6. 

Currently, we are using TF1.x. We will migrate to TF2.x in the coming months.  

:sparkles: A newer version compatible with Ubuntu 23 is being added in pnlp-refactor-ubuntu23.

We thank everyone, especially the educators & universities, for their feedback in pointing out the issues & improving the accessibility of the notebooks.
