Slides & Materials

You find the introduction slides under http://hilpisch.com/epat.pdf

You find the materials about OOP under http://hilpisch.com/py4fi_oop_epat.html

Python

If you have either Miniconda or Anaconda already installed, there is no need to install anything new.

The code that follows uses Python 3.6. For example, download and install Miniconda 3.6 from https://conda.io/miniconda.html if you do not have conda already installed.

In any case, for Linux/Mac you should execute the following lines on the shell to create a new environment with the needed packages:

conda create -n epat python=3.6
source activate epat
conda install numpy pandas matplotlib statsmodels
pip install plotly cufflinks
conda install ipython jupyter
jupyter notebook

On Windows, execute the following lines on the command prompt:

conda create -n epat python=3.6
activate epat
conda install numpy pandas matplotlib statsmodels
pip install plotly cufflinks
pip install win-unicode-console
set PYTHONIOENCODING=UTF-8
conda install ipython jupyter
jupyter notebook

Read more about the management of environments under https://conda.io/docs/using/envs.html

Docker

To install Docker see https://docs.docker.com/install/

docker run -ti -p 9000:9000 -h epat -v /Users/yves/Temp/:/root/ ubuntu:latest /bin/bash
