Installing SciPy on Ubuntu

I have Python 2.7 running and trying to install scipy by using easy_install which returns following errors:

Searching for scipy
Reading http://pypi.python.org/simple/scipy/
Reading http://www.scipy.org
Reading http://sourceforge.net/project/showfiles.php?group_id=27747&package_id=19531

So I installed Blas and Atalas by executing 

apt-get install blas
apt-get install atlas

However, the easy_install errors don't disappear.

Thanks!

If you are using Python3, You can install packages using apt-get

sudo apt-get install python3-numpy python3-scipy

If you want to still install using pip, you can use build-dep to get the dependencies of python-numpy and python-scipy, and then install using pip

sudo apt-get build-dep python-numpy python-scipy

Substitute for python3 as the other answers state of that's what you're looking for.

What worked for me:

To actually install scipy from PIP, you need packages libatlas-base-dev (libraries etc. for ATLAS/BLAS) and gfortran (GNU Fortran compiler).

Once these packages are installed, the scipy installer should finish as expected.

sudo apt-get install python-scipy worked in my case.

Ubuntu puts library files in a rather exotic directory. /usr/lib/x86_64-linux-gnu/ or something, depending on your architecture. You need to add this directory to the site.cfg file or the BLAS environment variable.

If easy install also needs the header files, you need to install the respective -dev packages.

But, like @pitsanu-swangpheaw suggests, you can also install to the site packages directory using the ubuntu package manager.

sudo apt-get install python-numpy python-scipy
