Extending python example.

[marciosdn]

I would like some help to understand "how to extend the python example".
Sry if I'm the noob here, but I'm googling and no good answer.

I don't understand:

Build the Docker image:
bash build.sh python-example examples/python

My goal is to install numpy to run with PySpark.

My cluster BDE looks work well (docker-compose.yml, 1 master, 3 workers, 1 hist-server).
I'm using Docker Desktop over Windows 10.
Also, I would like to try MLFlow and CML.
