I already tried
sudo apt-get install build-essential python-dev python-setuptoolssudo apt-get install python-numpy python-scipysudo apt-get install libatlas-dev libatlas3gf-base
It was showing Unable to locate package libatlas3gf-base
So I tried
pip install --user --install-option="--prefix=" -U scikit-learn
But it failed. Failure is in the image as shown in this drive link "https://drive.google.com/open?id=1_YZlQYpP5aGGbbEDKzIzsYeiEVIgEmGe".
