InstallPythonpackagesonUbuntu14.04

fromchris'sandbox

InthispostIwilldocumentmysetupofPython2.7.6inUbuntu14.04.Ofcourse,thebasePythonisinstalledbydefault,bothPython2.7.6andPython3.4.Trythefollowingintheterminal:

$python--version
Python2.7.6
$python2--version
Python2.7.6
$python3--version
Python3.4.0

Asyoucansee,usingpythonpointstoPython2.7.6bydefault.However,python2andpython3canbeusedtoaccessthedesiredversion.IwillfocusoninstallingpackagesforPython2.7.6here.

Strategy

InthepastIhaveinstalledPythonpackages:

UsingtheUbunturepository:

$sudoapt-getinstallpackagename

Or,fromagit/svnrepository:

$sudopythonsetup.pyinstall

Approach1hasmanyadvantagesforPythonusersthatdon’tneedtohavethelatestversionsofeverypackage.Inparticular,allofthepackagedependenciesincludingotherPythonpackages,linearalgebralibraries,etc.arealsoinstalledautomatically.Asaresult,ifyouarenewtoUbuntuandPython,strategy1isthewaytogo.

Iwilltakeadifferenttact,usingpiptoinstall,upgrade,andremovepackages.Also,IwillinstallallPythonpackagesasauser,thatis,nouseofsudo.ThismakesiteasytousethesameinstallprocedureonamachinewhereIdon’thavesudoprivileges–sayanUbuntucluster.However,Iwillneedsudotoinstallnon-Pythonlibraries,Fortrancompilers,etc.thatthePythonpackagesemploy.Onacluster,theSysAdminwouldhavetotodothispartformeandotherusers.

$pipinstall--userpyopensslndg-httpsclientpyasn1

Withthatwe’resecuredandthewarningsgoaway.Ifyouarejuststartingout,tryinstallingpip,asbelow,andreturntothisinstallifuseofpipgivesyouwarnings.

–endedit:2015,June1st–

pip

Ofcourse,thestartingpointistogetpipinstalled.Officialinstructionsarealsoavailableforinstallingpip.pipdependsonsetuptools,butwecaninstallbothusingtheget-pip.pyscript,asdescribedattheinstalllink.Tobeconcrete,Ididthefollowing:

$cd~/Downloads
$curl-Ohttps://bootstrap.pypa.io/get-pip.py$pythonget-pip.py--user

Ifyoudon’thavecurlinstalled,thiscanberemediedusing:

$sudoapt-getinstallcurl

Becausewehavechosenlocalinstallation,thepath~/.local/binhastobeaddedtoourpath.Todothat,addthefollowingtotheendofyour~/.bashrcfile:

#include.local/binforlocalpythonscripts
exportPATH=~/.local/bin:$PATH

Then,source~/.bashrc:

$source~/.bashrc

Trythefollowingtoseeifyougetsimilarresultsandtomakesurethebasicsetupisworking:

$whichpip

$pip--version

Ofcourse,yourusernameshouldbeinthepath,buttheoutputshouldlooksomethingliketheabove.

Ifyouhaveadminpermissionsyoucaninstallallpackagesgloballyusingacommandlike:

$sudopipinstallpackagename

CreateavirtualenvironmentandinstalleverythingtheretohaveacompletelyisolatedPythonenvironment–seevirtualenvandvirtualenvwrapperonUbuntu14.04foranexampleofhowtotakethisapproach.

Ubuntudependencies

AvarietyofUbuntu-specificpackagesareneededbyPythonpackages.Thesearelibraries,compilers,fonts,etc.I’lldetailtheseherealongwithinstallcommands.Dependingonwhatyouwanttoinstallyoumightnotneedallofthese.

Generaldevelopment/build:

$sudoapt-getinstallbuild-essentialpython-dev

Compilers/codeintegration:

$sudoapt-getinstallgfortran
$sudoapt-getinstallswig

Numerical/algebrapackages:

$sudoapt-getinstalllibatlas-dev
$sudoapt-getinstallliblapack-dev

Fonts(formatplotlib)

$sudoapt-getinstalllibfreetype6libfreetype6-dev

Morefonts(formatplotlibonUbuntuServer14.04–seecommentatendofpost)–added2015/03/06

$sudoapt-getinstalllibxft-dev

$sudoapt-getinstallpandoc

$sudoapt-getinstalllibxml2-devlibxslt-devzlib1g-dev

That’sit,nowwestartinstallingthePythonpackages.

numpy

numpyisoneofthefundamentalnumericalpackagesinPython.Toinstallusingpiptype:

$pipinstall--usernumpy

Thiswillresultinafairamountofcompilingfollowedbyanotethatthepackagewassuccessfullyinstalled.Ifnot,makeanoteoftheerror.Oftenthisresultsfromnothavinglibrariesand/orcompilersinstalled(seeabove).

$pipinstall--usermatplotlib

matplotlib复杂一点，可能直接上面的操作会失败：需要先安装其依赖的包libpng和freetype，根据提示缺啥就补安装啥即可：

安装libpng:sudoapt-getinstalllibpng-dev

安装freetype:

cd~/Downloads
