ML computers jupyter notebooks

Installation with pip3

• We will install jupyter notebooks with pip3 (not with anaconda)

pip3 install --upgrade pip
pip3 install jupyter

• Problem: no permissions
• Solution: Do not solve it with sudo! Instead change the permissions of all the directories that are needed:

sudo chmod -R a+w /usr/local/bin/jupyter
sudo chmod -R a+w /usr/local/bin/jupyter-kernel
sudo chmod -R a+w /usr/local/bin/jupyter-console

• And try again:

pip3 install jupyter

• Problem: Error -> ERROR: jsonschema 3.1.1 has requirement six>=1.11.0, but you'll have six 1.10.0
• Solution:

pip3 install --upgrade jsonschema==2.5.0
pip3 install jupyter

Usage

• To run the notebook

jupyter notebook 

• Already in the notebook.
• common problem: change pip to pip3 in case pip install libraries for the python 2 installation and you are working with notebook that uses python3

• First, we need to know that they are 2 modes in the Jypyter Notebook App: command mode and edit mode.

• Shortcuts in the both modes:
• Shift + Enter run the current cell, select below
• Ctrl + Enter run selected cells
• Alt + Enter run the current cell, insert below
• Ctrl + S save and checkpoint
