numpy Import Error on Ubuntu

Question

I am trying to import numpy in python on a server that I am not a sudoer. When I import, I get the following error:

ImportError: /usr/lib/liblapack.so.3gf: undefined symbol: ATL_chemv

I know that there are two conflicting libraries:

$ ls -l /etc/alternatives/*.so.3gf
lrwxrwxrwx 1 root root 39 Sep 21 21:31 /etc/alternatives/libblas.so.3gf -> /usr/lib/openblas-base/libopenblas.so.0
lrwxrwxrwx 1 root root 42 Aug 19  2014 /etc/alternatives/liblapack.so.3gf -> /usr/lib/atlas-base/atlas/liblapack.so.3gf

But all the solutions that I have seen so far (like here or here), require root access, which I don't have. Is there a quick way to resolve this?

I am running python 2.7.3 on Ubuntu 12.04.5.

Probably the easiest way to get NumPy and other scientific libraries to work is to use Anaconda or Miniconda.

While Anaconda is a full distribution of libraries, Miniconda is just a improved Python installation. After downloading and installing Miniconda, which you can do without being a sudoer, create a new environment:

conda create -n my_new_env python=3.5

Activate it with

source activate my_new_env

and install NumPy

conda install numpy

Do all your Python work from a shell you tyoed source activate my_new_env, in. The prompt should change to (my_new_env).

All steps can be done as "normal" user; no sudo right necessary.
