How to install scipy and numpy packages for python 3.4 on ubuntu 12.04?

I have tried installation with the following command:

sudo apt-get install python3-numpy python3-scipy

This installs the related packages for python 3.2. What should I do to install scipy and numpy for python >=3.4.2 ?
I have read the previous answers for the other questions on stack overflow regarding same issue but none have provided me with solution.

Please help

You can get various versions of python interpreters from

https://launchpad.net/~fkrull/+archive/ubuntu/deadsnakes

Then you can install virtualenvwrapper, and $ mkvirtualenv foo -p python-interpreter-you-want. This way, you get a virtualenv where you can pip install whatever you wish.

Demo: Here py35 is a virtualenv specifically for a python3.5 executable from the DeadSnakes repo linked above.

$ which python3.5
/home/br/virtualenvs/py35/bin/python3.5
$ workon py35
(py35)$ which python
/home/br/virtualenvs/py35/bin/python
(py35)$ ll /home/br/virtualenvs/py35/bin/python
lrwxrwxrwx 1 br br 9 Nov 12 16:21 /home/br/virtualenvs/py35/bin/python -> python3.5*

Notice that in the virtualenv, python is just a simlink to the executable you specified via the -p switch to mkvirtualenv.

I recently started using anaconda on Linux Mint and it really made my life much easier.

you can get miniconda here http://conda.pydata.org/miniconda.html

if you need to use 3.4 rather than 3.5 which is the defaul python3 for anaconda now, then you can create a separate env using python34

conda create -n myenv python=3.4

or just

conda create -n myenv python=3

to let conda pick the latest supported version

then

conda install -n myenv numpy=0.15.0

etc to install what you need. you can leave out the version too.

finally do

source activate myenv

to switch to the python interpreter of myenv.
