Install Anaconda or miniconda

Go to anaconda https://www.anaconda.com/download

Type your mail and get the link to download the free version of anaconda.

Go to your inbox and click on the link, now you can click on the download button.

Follow the steps to finish installation.

In my case I choose to not initialize the conda base environment at startup.
If you choose to initialize conda base at startup, and you want to disable it, execute the follow command:

conda config --set auto_activate_base false

To activate conda execute

eval "$(/home/julio/anaconda3/bin/conda shell.zsh hook)"

Only the first time you activate conda execute:

conda init
