How to install numpy on CentOS 7?

I'm working with Python 3.5.1 on a computer with CentOS Linux release 7.3.1611 (Core).

I have to install the numpy package. I tried to follow these instructions, by running the command:

sudo yum -y install python34-setuptools

Unfortunately, I got the following error:

Transaction check error:
  file /usr/lib64/libpython3.so from install of python34-libs-3.4.5-4.el7.x86_64 conflicts with file from package python3-libs-3.3.2-12.el7.nux.x86_64

Any idea on how to solve this problem?

On my machine, I have both Python 2.7 and Python 3.5, and I want to keep them both.

They should come pre-compiled with Centos OS, so try with:

sudo yum install numpy scipy.

So you have two option fist one is installing it system wide, like I mentioned they are pre-compiled with Centos OS, so you can Install the complete scipy packages with numpy like this:

sudo yum install python-numpy python-scipy python-matplotlib ipython ipython-notebook python-pandas python-sympy python-nose

Or you can use pip for the installation, like this:

python -m pip install --user numpy scipy matplotlib ipython jupyter pandas sympy nose

Please read the official docs from scipy organization on how to install all the packages on you system.

NOTE:

You are right that system wide installation will install it only for python2.7, so to use it for python3.5 you will install via pip, so do this:

sudo python3 -m pip install --upgrade pip

sudo python3 -m pip install --user numpy scipy matplotlib ipython jupyter pandas sympy nose

and I suggest that you install all of this packages, after the installation I've opened my terminal and I've did this:

copser@copser-LIFEBOOK-S751:~$ python3.5
Python 3.5.2 (default, Sep 14 2017, 22:51:06) 
[GCC 5.4.0 20160609] on linux
Type "help", "copyright", "credits" or "license" for more information.
>>> import numpy
>>> import numpy as np
>>> import numpy.f2py as myf2py
>>>

as you can see I've imported numpy inside python3.5.2 and it is working, I'm using Ubuntu 16.04 it should be the same on Centos OS.
