Install Python packages on raspberrypi

Just follow these simple steps to install Python packages - Numpy, Scipy, Scikit-learn, Matplotlib and Pywavelets on Raspberrypi

OS updates

==========

sudo apt-get dist-upgrade

sudo apt-get update

sudo apt-get upgrade

Python esential updates

=======================

sudo apt-get install libblas-dev        

sudo apt-get install liblapack-dev      

sudo apt-get install python-dev        

sudo apt-get install libatlas-base-dev  

sudo apt-get install gfortran          

sudo apt-get install python-setuptools

sudo apt-get install python3-setuptools

Numpy

======

sudo apt-get install numpy

Scipy

======

sudo apt-get install python-scipy            #for python 2

sudo apt-get install python-scipy --fix-missing

sudo pip3 install scipy                      #for python 3

Scikit-learn

============

sudo pip3 install scikit-learn           # for python 3

Matplotlib

==========

sudo apt-get install python-matplotlib

Pywavelets

=================

sudo apt-get install build essential

sudo apt-get install python-wheel

sudo apt-get install python3-dev

sudo pip3 install Pywavelets

sudo apt-get install python-dev

pip install PyWavelets

nothing else work clone the git and install

===========================================

sudo apt-get install git

sudo git clone git://github.com/scipy/scipy.git scipy

sudo git clone  git://github.com/scikit-learn/scikit-learn.git

sudo git clone https://github.com/PyWavelets/pywt.git PyWavelets

change dir to cloned directory and execute

sudo python setup.py install

Optional python packages

===================================

In case of errors please install these optional Python packages, it will fix.

sudo apt-get install python-dev libxml2-dev libxslt1-dev zlib1g-dev python3-dev

sudo apt-get install python-setuptools

In most cases it seems only build-essential and python-dev  are only required.

sudo apt-get install build-essential

sudo apt-get install python-dev

Remove unnecessary packages and free space

============================================

sudo apt-get purge libreoffice wolfram-engine sonic-pi scratch

sudo apt-get autoremove

Libre Offfice doesn't go? Give this a try :)

sudo apt-get remove --purge libreoffice*

sudo apt-get clean

sudo apt-get autoremove
