 By default, numpy, scipy and scikit-learn are installed in tox virtualenvs.
 This is slow, requires working build toolchain and is not always feasible.
 In order to skip numpy & friends, use ``..-nodeps`` environments::
 
-    tox -e py37-nodeps,py37,pypy

 It is also possible to run tests without tox. This way NLTK would be tested
 only under single interpreter, but it may be easier to have numpy and other
