Hi,

I tried to install auto-sklearn in a ubuntu docker, but stuck at pyrfr :

  Running setup.py install for pyrfr ... error
    Complete output from command /usr/bin/python -u -c "import setuptools, tokenize;__file__='/tmp/pip-build-d86q_ln9/pyrfr/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-zwpxskjr-record/install-record.txt --single-version-externally-managed --compile:

    ./include/rfr/trees/binary_fanova_tree.hpp:329: Error: Syntax error in input(3).
    error: command 'swig' failed with exit status 1

ENV:

• ubuntu 14.04 docker
• gcc 4.8.4
• swig 2.0.11
• python 3.5

I think this is related to #277 and you need swig3. Let me know if this solves the issue.

Change to swig3 works , thank you !

Solution here:

apt-get remove swig
apt-get install swig3.0
ln -s /usr/bin/swig3.0 /usr/bin/swig

!apt-get install swig -y
!pip install auto-sklearn
solved all the installation issues of auto-sklearn for me.

I noticed this issue still gets traffic, to clarify, swig4 will also work. In general, you can just install swig without specifying a version, as mentioned by @satyas13
