pandas==1.5.3
numpy==1.24.2
scikit-learn==1.2.1
All the pieces works completely. Now you add the mission to GitHub or ship it to another person. However — you haven’t informed them which libraries they should set up.
Let’s assume they do set up the required libraries, however perhaps with totally different variations than yours. Out of the blue, one thing breaks. A operate is lacking, or some syntax has modified.
Consequence?
Your program throws an error.
That is the place necessities.txt saves the day.
