I'm working on updating the code for Chapter 4 to ensure compatibility with newer versions of Python and updated libraries. This issue will track the progress and changes made for this specific notebook.

Notebooks:

• [ ] 01_OnePipeline_ManyClassifiers.ipynb
• [ ] 02_Doc2Vec_Example.ipynb
• [ ] 03_Word2Vec_Example.ipynb
• [ ] 04_FastText_Example.ipynb
• [ ] 05_DeepNN_Example.ipynb
• [ ] 06_BERT_IMDB_Sentiment_Classification.ipynb
• [ ] 07_BERT_Sentiment_Classification_IMDB_ktrain.ipynb
• [ ] #146
• [ ] #147
• [ ] 10_ShapDemo.ipynb
• [ ] 11_SpamClassification.ipynb

Tasks:

• [x] Update Python version from 3.6 to 3.9
• [x] Update Ubuntu version to 22.04
• [x] Update all Python libraries to their latest versions
• [x] Test the notebook to ensure it runs without errors

Context:

• Current Python Version: 3.6
• Current Ubuntu Version: 16.04
• Current Library Versions:

Proposed Changes:

• Update notebooks to run with Ubuntu 22.04
• Update notebooks to run with Python 3.10
• Libraries from each notebooks will be updated to latest version
• Markdown Text will be improved
