Install Python 3.7 (and IDLE3) on Ubuntu 19.10

This post show how to install Python 3.7 and IDLE (the integrated development environment for Python) on Ubuntu 19.10. Tested on VirtualBox running over Windows 10.

By default, Python 3 is installed on Ubuntu 19.10, currently Python 3.7.5rc1. You can run the command to install it if it's not installed:
$ sudo apt install python3

To run Python 3, simple enter the command:
$ python3

But IDLE is not installed by default. To install it, enter the command:
$ sudo apt install idle3

or

$ sudo apt-get install idle3

After installed, you can run IDLE with the command:
$ idle

TensorFlow Lite for Microcontrollers

TensorFlow Lite for Microcontrollers is an experimental port of TensorFlow Lite aimed at microcontrollers and other devices with only kilobytes of memory.

It is designed to be portable even to "bare metal" systems, so it doesn't require operating system support, any standard C or C++ libraries, or dynamic memory allocation. The core runtime fits in 16KB on a Cortex M3, and with enough operators to run a speech keyword detection model, takes up a total of 22KB.
