Scikit-learn tutorial documentation location

Question

I have scikit-learn 0.16.1 installed on Ubuntu 14.04 and am working through the tutorial. SKL was installed with all default configuration. The tutorial states

The source of this tutorial can be found within your scikit-learn folder: scikit-learn/doc/tutorial/text_analytics/

I've used find on my entire drive and there is no "tutorial" folder. Not anywhere. Anybody know where these files are really installed?

Answer 1

Finding the package contents

Where the packages are installed depends on how you installed scikit-learn

• If you used Ubuntu's package system via

  sudo apt-get install python-sklearn python-sklearn-doc
  

  (you often need the doc package to get the accompanying documentation), then the tutorial is simply missing. The doc/-folder it is not contained in the python-sklearn-doc-package. See the bug report.

  You can find out the contents of the package via

  dpkg-query --listfiles python-sklearn-doc
  

• If you used the Python Package Index to install it via

  pip install --user --install-option="--prefix=" -U scikit-learn
  

  , then the installation should be at $HOME/.local/lib/python2.7/site-packages/sklearn. (as also of pip show -f scikit-learn) But a

  find . | grep -i tutorial
  

  did not find any tutorial/-folder.

• If you installed it from source, consider reinstalling via pip, as the warning states that

Warning

Packages installed with the python setup.py install command cannot be uninstalled nor upgraded by pip later. To properly uninstall scikit-learn in that case it is necessary to delete the sklearn folder from your Python site-packages directory.

Solution

A solution would be to use the source. Either download the master file or do it via git:

    git clone https://github.com/scikit-learn/scikit-learn.git

The git archive is more than 60 MiB, so you might want to prefer the master zip.
