I just download the scikit-learn install package from https://pypi.python.org/pypi/scikit-learn/.
Before install the package, I install several dependent package using apt-get:

sudo apt-get install build-essential python-dev python-numpy python-setuptools python-scipy libatlas-dev

After I go to the install directory, I run the command python setup.py install. But receive the response error: could not create '/usr/local/lib/python2.7/dist-packages/sklearn': Permission denied

I found the problem is about the ATLAS and BLAS, but I am not familiar with them. So I need some help to solve it. I paste the details in the terminal:

Answer 1

The problem is not about ATLAS and BLAS, it'a about you need to be super user to write into /usr directory. Try

sudo  python setup.py install

An alternative (and probably easier) way is to install direktly from the ubuntu repositories:

sudo apt-get install python-sklearn
