Hi Lifan.
It looks like there's something wrong with your scipy installation (or
python installation?)
Can you try
from scipy.sparse.linalg.interface import aslinearoperator
and
import dis
Btw, where did you get these installation instructions from?
The Readme?
Best,
Andy

Hi guys,
I am sorry to bother you. But I have a question about using
scikit-learn in ubuntu.
I installed scikit using:
sudo apt-get install build-essential python-dev python-numpy
python-numpy-dev python-scipy libatlas-dev g++ python-matplotlib ipython
sudo pip install -U scikit-learn
However, when I try to use scikit, I got this error:
Python 2.7.6 (default, Jun 22 2015, 17:58:13)
[GCC 4.8.2] on linux2
Type "help", "copyright", "credits" or "license" for more information.

Anyone knows how to fix this problem?
Thanks!
