scikit-learn: pip install scikit-learn fails in my virtualenv

When I’m installing the package following shows up:

Command "<my-directory>/dev_env/bin/python3.6 -u -c "import setuptools, tokenize;__file__='/tmp/pip-build-ya0bvm5k/scikit-learn/setup.py';f=getattr(tokenize, 'open', open)(__file__);code=f.read().replace('\r\n', '\n');f.close();exec(compile(code, __file__, 'exec'))" install --record /tmp/pip-9skvu63c-record/install-record.txt --single-version-externally-managed --compile --install-headers <my-directory>/dev_env/include/site/python3.6/scikit-learn --home=/tmp/tmpw1u1nxgr" failed with error code 1 in /tmp/pip-build-ya0bvm5k/scikit-learn/

@root-sudip This is not related to openblas or lapack. You should install python-dev or python-devel depending of your distribution.

The important message in the traceback is:

sklearn/__check_build/_check_build.c:15:20: fatal error: Python.h: No such file or directory
#include "Python.h"
                  ^
compilation terminated.

Why are you using 3.6-dev?? Perhaps you mean Python 3.7, which we don’t yet support. We’re likely to release version 0.19.2 with Python 3.7 support in the next couple of days.

no you should install python-dev via the system package manager. For ubuntu it should be:

apt-get install python-dev
