Installing Anaconda in GNU/Linux Mint

Download Miniconda

Download Miniconda for Python version 3 (we would be able to run both Python major versions). The URL for Miniconda download is https://docs.conda.io/en/latest/miniconda.html where you should choose the option for 64-bit Linux.

Your first jupyter notebook

You can launch a notebook with the command

Or copy and paste one of these URLs:

Copied!
By default you can only access notebooks and directories below the folder from which you run the jupyter notebook command, but not files above this folder. You can alter this default behavior and other jupyter default config options editing the application config file as in the following example.
You first generate a config file for your notebooks
1
(py3) [email protected]:~$ jupyter notebook --generate-config
2
Writing default config to: /home/curro/.jupyter/jupyter_notebook_config.py
3
(py3) [email protected]:~$ ls ~/.jupyter/
4
jupyter_notebook_config.py
Copied!
This file contains the default configuration of jupyter. In order to create a folder and make this directory the default working directory for our notebooks, you can proceed as follows (not recommended unless you are positive all of your notebooks will be contained in this folder and its subfolders
1
(py3) [email protected]:~$ mkdir ~/Python
Copied!
You should then open the jupyter_notebook_config.py file in a text editor and replace the line
1
#c.NotebookApp.notebook_dir = ''
Copied!
by
1
c.NotebookApp.notebook_dir = 'ISP/Python'
Copied!

Keeping your Anaconda install updated

The most important command in this case is
1
conda update --all
Copied!
This will update all packages in the current environment. You can also update a selected package or packages (and dependencies) as follows
1
conda update numpy scipy
Copied!
Again this will only affect the current environment.
