On Ubuntu 14.04, I installed python 2.76. then scipy as shown here , namely through
sudo apt-get install python-numpy python-scipy python-matplotlib ipython ipython-notebook python- pandas python-sympy python-nose
The python -c "import numpy; numpy.test()" test python -c "import numpy; numpy.test()" ends without errors, but python -c "import scipy; scipy.test()" results in:
ERROR: test_fitpack.TestSplder.test_kink

What should I do?
