Hi!
I just tried to install from source using instructions
http://scikit-learn.org/stable/install.html I installed all packages and
did "sudo pip install -U scikit-learn".
After installing did:
python -c "import sklearn; sklearn.test()"
Ran 993 tests in 35.552s
FAILED (SKIP=6, errors=6)
I got 6 Doctests errors, all were in the same line of code. One example
here.
ERROR: Doctest: sklearn.datasets.base.load_sample_images
----------------------------------------------------------------------
Traceback (most recent call last):
File
"/usr/local/lib/python2.7/dist-packages/nose/plugins/doctests.py", line
395, in tearDown
delattr(builtin_mod, self._result_var)
AttributeError: _
I guess its not a big problem because its doctests and installation is
ok? I looked at the source file
"/usr/local/lib/python2.7/dist-packages/nose/plugins/doctests.py" and
wonder some things:
def tearDown(self):
super(DocTestCase, self).tearDown()
if self._result_var is not None:
sys.displayhook = self._old_displayhook
delattr(builtin_mod, self._result_var)
It seems that self._result_var is initialized to "_" in
DocTestCase.__init__()
so self.result_var will never be None...because it is assigned in two
places in this file, and
neither assigns None to it.
Perhaps better would be something like if hasattr(builtin_mod,
self._result_var) ?
So it would protect using delattr() when there is no such attribute to
delete...
I tried it and now I dont get DocTesterrors.
def tearDown(self):
super(DocTestCase, self).tearDown()
#if self._result_var is not None:
if hasattr(builtin_mod, self._result_var):
sys.displayhook = self._old_displayhook
delattr(builtin_mod, self._result_var)
Ran 993 tests in 34.766s
OK (SKIP=6)
