Machine learning on a Chromebook
Requirements
To set up a machine learning environment with Python 2.7.6 on a Chromebook Acer C720 with Ubuntu 14.04.5 LTS installed via crouton. The following Python libraries are required:
It is also required to have Jupyter Notebook installed to run and execute the code.
Instructions:
Install python 2.7, python-pip and python-dev
sudo apt-get install python2.7 python-pip python-dev
To verify that you have python and pip installed:
python --version
pip --version
Installing Ipython
sudo apt-get install ipython ipython-notebook
Installing Jupyter Notebook
-H, --set-home Request that the security policy set the HOME environment variable to the home directory specified by the target user's password database entry. Depending on the policy, this may be the default behavior.
sudo -H pip install jupyter
If any error --> Upgrade pip to the latest version
sudo -H pip install --upgrade pip
Try installing Jupyter again
sudo -H pip install jupyter
Running Jupyter Notebook
jupyter notebook
scipy, matplotlib, pandas and others
sudo apt-get install -f build-essential python-dev python-setuptools python-numpy python-numpy-dev python-scipy libatlas-dev libatlas3gf-base libfreetype6-dev libpng-dev g++ python-matplotlib python-pandas
seaborn
Download latest version of seaborn .tar.gz
tar -xzf seaborn-file.tar.gz
cd seaborn-path/
sudo python setup.py install
Using Jupyter Notebook
Automatically, Jupyter Notebook will show all of the files and folders in the directory it is run from.
To create a new notebook file, select New > Python 2 from the top right pull-down menu.
This will open a notebook. We can now run Python code in the cell or change the cell to markdown. For example, change the first cell to accept Markdown by clicking Cell > Cell Type > Markdown from the top navigation bar. We can now write notes using Markdown and even include equations written in LaTeX by putting them between the $$ symbols. For example, type the following into the cell after changing it to markdown:
# Simple Equation
Let us now implement the following equation:
$$ y = x^2$$
where $x = 2$
To turn the markdown into rich text, press CTRL+ENTER:
You can use the markdown cells to make notes and document your code. Let's implement that simple equation and print the result. Select Insert > Insert Cell Below to insert and cell and enter the following code:
x = 2
y = x*x
print y
