Getting started

Lorsqu’on fait des statistiques, le language Python est loin d’être aussi complet que R qui a été pensé dans ce but. Il faut lui ajouter plusieurs dizaines de modules. C’est à ce moment qu’on découvrir les subtilités dans les différents systèmes d’exploitations, les compilateurs, les dépendances, la ligne de commande. Ce paragraphe décrit un moyen d’installation Python sur les trois systèmes principaux Windows, OS X, Linux avec les modules nécessaires présentés dans ce cours. Le premier paragraphe explique comment installer rapidement Python, il faudra lire les suivants si vos besoins vont au delà.

Notes

La grande majorité des exemples et des notebooks proposés sur ce site sont testés une fois par semaine. La distribution utilisée varie mais s’appuie sur les dernières versions des modules. Une part moins importante est également testée à chaque modification sur github/sdpython sur Windows, Linux (Ubuntu) et Linux (Debian).

2018-2019

Pour l’année 2017, les tests sont dorénavant effectués sur Linux Debian 9 et la distribution standard Python 3.7.0. L’installation de cette machine est assez fastidieuse. Les traces de l’installation sont conservées sur cet article de blog : Install Python 3.7 and many packages on Linux Debian 9. Il reste quelques problèmes comme TensorFlow qui n’est pas encore compatible avec Python 3.7 (août 2018) mais cette pull request devrait résoudre le problème.

2017-2018

Toutes les modules étaient testées sur Windows 10 et une distribtion standard Python 3.6.4 puis Python 3.6.5 64 bits.

En résumé : Anaconda

En résumé, le conseil le plus fréquent qu’on donne à ceux qui souhaitent installer Python est d’utiliser la distribution Anaconda. C’est l’équivalent de R. Sans autre étape supplémentaire, elle permet de faire du calcul matriciel numpy, de tracer des graphiques avec matplotlib, de manipuler les données pandas et de faire du machine du machine learning scikit-learn. La plupart des exercices proposés sur ce site n’utilisent pas plus que ce qui est proposé dans cette distribution standard. Pour les autres, les instructions mentionnées ci-dessous fonctionnent sous Windows, Linux et Mac.

• Installation Anaconda (python 64 bit)

• Mise à jour de la distribution avec conda update --all (en ligne de commande).

Pour installer le module implémenté pour ce cours :

• pip install ensae_teaching_cs

Windows

Certains modules nécessitent une compilation C++. Anaconda fournit la plupart d’entre eux. Pour les autres, il faut allez à Unofficial Windows Binaries for Python Extension Packages. Certains modules n’existent pas sous forme précompilée à moins de le faire soi-même. Et c’est ce que j’ai fait pour certains modules comme dlib.

pip install pymyinstall

Linux en ligne de commande / MacOS

Voir Install Miniconda through SSH connection. Cela fonctionne avec les distributions Ubuntu 14.04 et Ubuntu 16.04. Vous pouvez par exemple suivre les instructions utilisées pour tester et compiler ce site disponibles dans le fichier config.yml. Les sorties disponibles sur le site CircleCI peuvent vous aider à comprendre les erreurs si vous en avez.

Les mêmes instructions devraient fonctionner sous MacOS depuis une fenêtre terminal car ce système s’appuie sur une distribution Linux.

IDE

Un IDE est un environnement de développement. Et comme on ne fait pas tout depuis un notebook, il faut en choisir un un.

• Atom

• Ninja IDE

• PTVS (Python Tools for Visual Studop)

• PyCharm

• PyDev (fonctionne avec Eclipse)

• Pyzo : ressemble à Matlab (anciennement IEP)

• WingIDE

Editeur de texte

Si vous êtes dans le train et que vous n’avez pas beaucoup de batterie, il faut revenir à l’essentiel : un éditeur de texte.

• Emacs

• nano (linux)

• Notepad++

• SciTE, le plus simple et le plus léger, lire cet article pour le configurer Installer Python pour faire des statistiques.

Installer un module

pip, python et ligne de commande

Le language python s’est doté d’un système de distribution de modules (ou packages) qui est aisément accessible depuis la ligne de commande. Sous Windows, on peut lancer la ligne de commande par la commande cmd. Sous Linux ou OS/X, c’est une fenêtre terminal (Linux, OS/X). Il suffit alors de se déplacer dans le répertoire d’installation de Python

cd c:\Python370_x64\Scripts

Ou encore :

cd c:\Anaconda3\Scripts

Puis d’écrire :

pip install <module>

Sous Linux ou OS/X (Apple), la ligne de commande s’appelle le terminal. Comme Python est déjà installé en version 2.7, je recommande l’installation de la distribution Anaconda en version 3.6 qui facilite la coexistence de plusieurs versions de Python. On procède de la même manière

cd /home/<alias>/anaconda3/bin

Puis

pip install <module>

Pour vous assurer que cela correspond bien à la version de Python souhaitée, il suffit de demander la version installée

pip --version

Sous Windows, pour l’ajout d’un module ponctuel, si l’instruction pip install <module> ne fonctionne pas, c’est vraisemblablement parce que ce module contient une partie en C++. Dans ce cas, il faut aller voir sur ce site Unofficial Windows Binaries for Python Extension Packages s’il est disponible. S’il ne l’est pas, l’installation du module est réservée aux experts.

conda ou pip

Anaconda maintient des versions de librairies Python. Pour tous les modules de cette liste, Anaconda Package List, il faut utiliser conda install <module>. Pour les autres, pip install <module>. Cela ne fonctionne qu’avec la distribution Anaconda.

L’instruction pip install ne fonctionne pas sous Windows lorsque le module est implémenté en Python et C++. C’est pourquoi il est préférable d’installer une version précompilée.

Dépendances

Par défaut, l’installation d’un module implique celle de ses dépendances ce qu’il est possible d’éviter :

pip install <module> --no-deps

Installer un module avec pymy_install

Le module pymyinstall recherche la meilleure façon d’installer un module quelque soit votre installation. Pour l’installer ou le mettre à jour :

pip install pymyinstall --upgrade

L’installation du module crée deux scripts, pymy_install3 pour installer un module, pymy_update3 pour mettre à jour. Le module permet aussi d’installer un ensemble de modules. La ligne suivante installe un module développé pour ce cours et ses dépendances :

pymy_install3 --set=pyensae

Désinstallation des modules implémentés pour ce cours

Il est possible de désinstaller simplement les modules installés pour ces enseignements :

    pip uninstall -y _benchmarks
    pip uninstall -y _check_python_install
    pip uninstall -y actuariat_python
    pip uninstall -y botadi
    pip uninstall -y code_beatrix
    pip uninstall -y cpyquickhelper
    pip uninstall -y csharpy
    pip uninstall -y csharpyml
    pip uninstall -y ensae_projects
    pip uninstall -y ensae_teaching_cs
    pip uninstall -y ensae_teaching_dl
    pip uninstall -y jupytalk
    pip uninstall -y jyquickhelper
    pip uninstall -y lecture_citation
    pip uninstall -y lightmlboard
    pip uninstall -y lightmlrestapi
    pip uninstall -y machinelearningext
    pip uninstall -y manydataapi
    pip uninstall -y mathenjeu
    pip uninstall -y mlinsights
    pip uninstall -y mlprodict
    pip uninstall -y mlstatpy
    pip uninstall -y myblog
    pip uninstall -y pandas_streaming
    pip uninstall -y papierstat
    pip uninstall -y pyenbc
    pip uninstall -y pyensae
    pip uninstall -y pymlbenchmark
    pip uninstall -y pymmails
    pip uninstall -y pymyinstall
    pip uninstall -y pyquickhelper
    pip uninstall -y pyrsslocal
    pip uninstall -y pysqllike
    pip uninstall -y python3_module_template
    pip uninstall -y sparkouille
    pip uninstall -y teachpyx
    pip uninstall -y tkinterquickhelper
    pip uninstall -y wrapclib

Configuration pour ces cours

Les notebooks utilisent le module pyensae développé pour ces enseignements. Pour installer ses dépendances, il faut utiliser le module pymyinstall. Les dépendances s’installent comme suit :

pymy_install3 --set=ensae_teaching_cs
pip install ensae_teaching_cs

Certains notebooks requièrent des outils supplémentaires :

• GraphViz

Compiler un module

• Compiler les librairies Python sous Windows

Distributions

• Anaconda (Windows, Linux, Mac). Sous Linux ou OS/X, la distribution n’interfère pas avec la distribution existante souvent différente. C’est un point très appréciable. Les modules de la distribution ne sont pas tous à jour. Il faut penser à mettre à jour avec la commande conda install <module> depuis le répertoire Anaconda3/Scripts (conda install cvxopt par exemple). Il existe une version différente : miniconda. La liste des packages manquant sera probablement différente. Il suffit d’écrire sur la ligne de commande conda update --all pour mettre à jour tous les modules.

• WinPython (Windows). Sous Windows, elle inclut parfois R ou Julia (ces version ne sont pas aussi à jour que la version principale). On passe alors facilement de python à R ou Julia depuis le même notebooks. Uniquement disponible sous Windows, cette installation a l’avantage de ne pas nécessiter les droits administrateur pour être installée. Elle ne modifie pas les registres et on peut la recopier telle quelle sur une clé USB pour la recopier sur un autre ordinateur. On peut également préparer sa propre version How To Make WinPython.

• Distribution officielle de Python, il faut ensuite installer de nombreux modules (voir Liste exhaustive de modules Python) pour obtenir une distribution équivalente aux deux précédentes.

• miniconda est une version light de Anaconda sans tous ces packages. Elle peut être installée depuis une ligne de commande, via une connexion SSH. Voir Install Anaconda through SSH connection.

La liste des packages de WinPython ou Anaconda sont d’excellents moyens de découvrir de nouveaux modules intéressants.

Modules incournables pour un data scientist

Les modules indispensables sont intégrés à la distribution Anaconda, WinPython.

Les indispensables

• dask : dataframe distribué et capables de gérer des gros volumes de données (> 5Go)

• Jupyter : gestion des notebooks (des pages blanches mélangeant code, équations, graphiques)

• matplotlib : graphes scientifiques

• numpy : calcul matriciel

• pandas : gestion de DataFrame

• Scipy : calcul scientifique

• scikit-learn : machine learning, statistique descriptive

• statsmodels : séries temporelles

Visualisation

Voir 10 plotting libraries at PyData 06/14/2016 in Paris.

Jeux

• pygame + thorpy

• kivy : pour faire des jeux ou des applications pour tablettes, téléphones

Pour les TD et projets à l’ENSAE

• pyensae : outils pour les élèves de l’ENSAE

• pyquickhelper : outils d’automatisation

Pour faire du machine learning sans programmer

• Orange3

Outils, ressources pour développer

Développer un programme informatique prend du temps et il est important d’être à l’aise. Une grande difficulté lorsqu’on programme c’est de travailler à plusieurs sur le même projet. Il faut se sychroniser. Fort heureusement, le problème est connu depuis longtemps et il existe beaucoup d’outils open source dont on aurait tort de se passer ou des services gratuits sous certains conditions qui facilitent l’archivage.

En vrac

Suivi de sources distant

• GitHub : c’est le site par référence pour tous les projets open source.

• GitLab

• BitBucket

Git

git est un logiciel de suivi de source. Il a supplanté tous les autres et il est indispensable aujourd’hui de le connaître. On ne retient pas toujours les commandes mais un moteur de recherche fournit rapidement la réponse. Voir aussi Cheat Sheet.

• Git + GitHub : pour suivre ses projets avec Git

• TortoiseGit (Windows)

Archivage distant

• hubiC (25 Go gratuit - août 2015)

• OneDrive (15 Go gratuit - août 2015)

Ce ne sont pas les seuls, vous trouverez d’autres options ici : cloud-gratuit. Toutefois, il est recommandé de faire attention avec les données personnelles sensibles. Il n’est pas toujours possible de choisir le lieu de stockage et chaque pays a une législation différente. Même si vos données sont protégées par un mot de passe et ne sont pas publiques, il arrive que certains mots de passe soient interceptés.

Comparaison de fichiers

• kdiff3

• Beyond and Compare : il est gratuit pendant un mois, c’est le plus convivial.

Partager des notes, des idées

• OneNote

• Evernote

• Google Docs

Editeur de texte

• SciTE : le plus simple, pas d’explorateur de fichier, pas d’installeur, autocomplétion perturbante

• TextWrangler (seulement sur iOS - Apple)

• SublimeText : configuration nécessaire avant d’exécuter un script python

• Notepad++ : configuration nécessaire avant d’exécuter un script python

IDE

• Atom

• Ninja IDE

• PyCharm

• PyDev (fonctionne avec Eclipse)

• PTVS (fonctionne avec Visual Studio)

• Pyzo : ressemble à Matlab (anciennement IEP)

• WingIDE

Python et Domotique

• Micro Python Project

• Python et Arduino

• Python et RaspberryPI

Navigateur

Les navigateur sont importants pour l’utilisation des notebooks. Je recommande soit Firefox, soit Chrome. Ces deux navigateurs sont indispensables si vous insérez du javascript dans nos notebooks. Le débuggeur de Chrome est le plus pratique à utiliser quand il s’agit d’aller fouiller dans les feuilles de styles ou de voir l’exécution du javascript.

Documentation

La documentation et les tests unitaires les modules classés dans les catégories SPHINX, TEACH (voir table ci-dessous). Certaines séances pratiques utilisent des données depuis ce site. Elles sont facilement téléchargeables avec ces deux modules :

• pyquickhelper : ce module compile ce cours

• pyensae : outils variés pour les élèves de l’ENSAE

• pymyinstall : installer facilement des modules sous Windows

Pour être compilée, la documentation requiert également :

• GraphViz : représenter des graphes

• InkScape

• MiKTeX (Windows seulement)

• pandoc

Continuous build

• Buildbot

• Java : nécessaire pour Jenkins et Antlr

• Jenkins (plus les plugins pour GitHub, git, python, pipeline, Build timeout plugin, Console column plugin, Next executions, Collapsing Console Sections Plugin, Exclusive Execution)

• Visual Studio Community Edition 2015 : C++, C#, F#, Python avec PTVS

• MinGW : compilateur C++

Compression

• 7zip : pour compresser, décompresser tous les formats

Ressources

• Developpez.com : beaucoup de choses autour de la programmation et en français

• stackoverflow : énorme forum de discussion sur tout ce qui touche à la programmation

• Jardin Zen Css (la même page avec une multitude de styles différents)

• Le blog univers domotique

• Tutoriel sur GIT

Générer une documentation comme ce cours

Lire List of tools needed to build the documentation.

Setup pour déveloper ce cours (Windows)

• 7zip

• Anaconda 2 et 3 (à installer sur le même disque que le répertoire utilisé pour Jenkins)

• Chrome

• CMake (pour compiler XGBoost)

• Graphviz

• Git

• GitHub

• Java 64 bit

• Jenkins

• Miktex basic installer 64 bit (lors de l’installation, il faut cocher l’installation automatique de nouveaux packages)

• Pandoc

• Python 3.5, 3.6, 2.7 64 bit (il ne faut pas ajouter les interpréteur au PATH par défaut)

• R 3.2.2

• SciTE

• Visual Studio 2015 Community Edition (cocher C++, C#, Python comme langage + CLang comme compilateur)

Pour chaque version de Python, il faut installer pymyinstall puis écrire pymy_install puis supprimer les modules qu’on souhaite compiler et tester (voir Désinstallation des modules implémentés pour ce cours).

Quelques modules particuliers : plus trop maintenus mais parfois utiles et parfois modifiés

pip install https://github.com/sdpython/pyPdf/archive/trunk.zip

En plus :

• Cygwin

• FileZilla

• InnoSetup (version unicode)

• Aria2

Pour Jenkins, quelques extensions :

• Build timeout plugin

• Collapsing Console Sections Plugin

• Console column plugin

• Extra Columns Plugin

• Next Executions

• Text File

• Startup Trigger : automatisation de build

Pour Jupyter :

pip install widgetsnbextension
jupyter nbextension enable --py --sys-prefix widgetsnbextension

Un serveur en local doit être démarré, la ligne de commande ressemble à ceci :

c:\Python370_x64\Scripts\pypi-server.exe -u -p 8067 --disable-fallback ..\..\local_pypi\local_pypi_server

Si le serveur Jenkins utilise des mots-clés via keyring, ce qui est le cas pour plusieurs modules utilisés pour ces enseignements, il est nécessaire de créer un serveur un serveur Jenkins authentifié. Sous Windows , il faut chercher services.msc et renseigner les identifiants. Pour certains projets (comme la compilation de pywin32), il faut installer Windows SDK.

Maintenir sa distribution Python à jour

Manipuler les données est différent de savoir programmer. Si le second est nécessaire au premier, il est impensable aujourd’hui de ne pas tenir compte ce que d’autres programmeurs ont mis à disposition de tous en libre accès. Tous les modules proposés dans la suite sont utilisées par beaucoup, et sont très adaptés à la manipulation des données. Ils bénéficient de ce fait d’un développement rapide et d’une robustesse qu’il faut environ un an à un bon programmeur pour obtenir avec un de ses outils sur le même éventail de fonctionnalités (en y consacrant 10 à 20% de son temps).

J’ai cherché à regrouper les outils qui permettent à un ingénieur, statisticiens, data scientist de manipuler aisément des données, qui peuvent aller de quelques kilo-octets à quelques giga octets. En tant que data scientist, je pioche très régulièrement des éléments des sept premiers chapitres. Les sept suivants ne sont utiles que de temps en temps, surtout si les données sont de taille supérieure à 250 Mo.

L’essentiel n’est pas de tout faire en Python, l’essentiel est d’être agile, de passer le moins de temps sur l’implémentation et le plus de temps possible sur les données.
