ST STM32

Switching between Arduino cores:
There are three different Arduino cores for STM32 microcontrollers: STM32Duino, Arduino STM32 (maple) and STM32L0. All of them have been developed independently, therefore, have different functionality and set of internal libraries. By default, official STM32Duino core is used (except cases when a board supports only one specific core).

What is Anaconda

What is the difference between pyenv, virtualenv, anaconda?

Miniconda

Preparing transaction: done
Executing transaction: done
installation finished.
Do you wish the installer to initialize Miniconda3
by running conda init? [yes|no]
[no] >>> no

You have chosen to not have conda modify your shell scripts at all.
To activate conda's base environment in your current shell session:

eval "$(/home/bacr/miniconda3/bin/conda shell.YOUR_SHELL_NAME hook)" 

To install conda's shell functions for easier access, first activate, then:

conda init

If you'd prefer that conda's base environment not be activated on startup, 
   set the auto_activate_base parameter to false: 

conda config --set auto_activate_base false

Thank you for installing Miniconda3!
