Installation of pyenv and virtualwrapper on Ubunto/Debian

Although Ubunto/Debian machines come already set up with Python 2.7.12, we might need different versions of python for experimentation. To do that we will use pyenv and virtualwrapper.


pyenv is a software that allows to switch between multiple versions of python. It is advantageous if you want to have a per-project version of Python, allows the creation and management of virtual-environments.

Installing dependencies

To install the dependencies for pyenv run the following code:

import numpy as np
import pandas as pd
import scipy.stats
from math import sqrt
def cramers_v(x, y):
confusion_matrix = pd.crosstab(x, y)
chi2 = scipy.stats.chi2_contingency(confusion_matrix)[0]
n = confusion_matrix.sum().sum()
