data-science-ipython-notebooks

This repo is a collection of IPython Notebooks I reference while working with data. Although I developed and maintain most notebooks, some notebooks I reference were created by other authors, who are credited within their notebook(s) by providing their names and/or a link to their source.

For detailed instructions, scripts, and tools to more optimally set up your development environment for data analysis, check out the dev-setup repo.

notebook-installation

anaconda

Anaconda is a free distribution of the Python programming language for large-scale data processing, predictive analytics, and scientific computing that aims to simplify package management and deployment.

Follow instructions to install Anaconda or the more lightweight miniconda.

pip-requirements

If you prefer to use a more lightweight installation procedure than Anaconda, first clone the repo then run the following pip command on the provided requirements.txt file:

$ pip install -r requirements.txt

running-notebooks
