I wanted to give scikit-automl a try, but I don’t like to install many packages on my machine. Conda solves the problem of creating a mess, although it does not deal with the issue of running unknown code on my computer. Hence, I decided to try it on Kaggle.
I followed the installation instructions and did not expect any issues. After all, the instruction consists of only two steps:
!curl https://raw.githubusercontent.com/automl/auto-sklearn/master/requirements.txt | xargs -n 1 -L 1 pip install
!pip install auto-sklearn
What can go wrong?
Swig. Swig can go wrong. I was installing the packages, and at some point, I saw this error message. Pip was installing the pyrfr package but failed because of a problem with swig.
building 'pyrfr._regression' extension
swigging pyrfr/regression.i to pyrfr/regression_wrap.cpp
swig -python -c++ -modern -features nondynamic -I./include -o pyrfr/regression_wrap.cpp pyrfr/regression.i
unable to execute 'swig': No such file or directory
error: command 'swig' failed with exit status 1
It turns out that Kaggle has some old swig version installed on their machines, but we can quickly fix it:
!apt-get remove swig
!apt-get install swig3.0
!ln -s /usr/bin/swig3.0 /usr/bin/swig
After that change, I ran the installation script, and everything worked fine.
