I am currently encountering below issues when trying to install any version of Scikit Learn (0.19.0 or 0.19.1 or 0.19.2) for Python 3.7 or 2.7 on Linux - RHEL / Centos 7 OS.
Few months back I could successfully install scikit-learn under python 2.7 without issues. When I re-run the installation of scikit-learn package under python 2.7 its failing with the same below error.
I have installed all the required OS and Python package dependencies prior to installing the scikit-learn
I have installed all the prerequisite - OS packages - blas-devel , lapack-devel , atlas-devel.
Python Version - 3.7
/usr/local/bsb-python37 - Custom Location in which I configured and installed Python 3.7
Steps I followed to install Python and Python Packages.
Installed Python with below steps - Followed the same procedure for Python 2.7 and 3.7
Install Python 2.7
bash "build-and-install-python2.7" do
cwd '/tmp/python'
code <<-EOH
tar -xvf Python-2.7.14.tgz --no-same-owner / tar -xvf Python-3.7.0.tgz --no-same-owner
sleep 10
cd Python-2.7.14 / cd Python-3.7.0
./configure --prefix=/usr/local/bsb-python27 (and bsb-python37)
make && make altinstall
EOH
not_if { ::File.exist?('/usr/local/bsb-python27/bin/python2.7') }
end
Package Installation Steps
Install scikitlearn
bash "scikitlearn-install" do
cwd '/tmp/python'
code <<-EOH
tar xzvf scikit-learn-0.19.0.tar.gz or scikit-learn-0.19.1.tar.gz or scikit-learn-0.19.2.tar.gz
sleep 10
cd scikit-learn-0.19.1 or cd scikit-learn-0.19.1 or scikit-learn-0.19.2
/usr/local/bsb-python27/bin/python2.7 setup.py install --prefix=/usr/local/bsb-python27
EOH
not_if " /usr/local/bsb-python27/bin/python2.7 -c 'import sklearn;' "
end
Few months back when I installed scikit-learn under Python 2.7 I didn't run into any issues. Now when I re-try to install the scikit learn under Python 2.7 I am running into the same issue and the earlier successful installed version of scikit learn is corrupted.

Any help is greatly appreciated. I tried to google around and did all that I could try. No luck.
scikit-learnhas not been updated to be used with python 3.7. So even if you solve the above errors, it would through some warnings and maybe errors during using. – Vivek Kumar
