Brent hit it right on!
I had optimisation level set to 2 which does remove the docstrings from the exe.
Reverting to level 1 (i.e. python -O (only optimize the bytecode) ) fixes the
docstring problem.
Good work! :-) and many thanks.

Hello François,
Thanks for the pointer. The explicit import solved one problem.
Unfortunately, Py2exe had more surprises in store for us.
Py2exe will compile the following source
from sklearn.utils import weight_vector
from sklearn.decomposition import PCA
Pass
But the exe will crash with
Traceback (most recent call last):
File "exe.py", line 3, in <module>
File "zipextimporter.pyo", line 82, in load_module
File "sklearn\decomposition\__init__.pyo", line 8, in <module>
File "zipextimporter.pyo", line 82, in load_module
File "sklearn\decomposition\pca.pyo", line 302, in <module>
File "sklearn\decomposition\pca.pyo", line 304, in ProbabilisticPCA
TypeError: unsupported operand type(s) for +=: 'NoneType' and 'NoneType'
So the offendinbg lines (to py2exe) in PCA are
302 class ProbabilisticPCA(PCA):
303 """Additional layer on top of PCA that adds a probabilistic evaluation"""
304 __doc__ += PCA.__doc__
Seems py2exe can't stomach line 304.
Commenting 304 out (innocuous enough I think) makes the thing fly :-)))
This could be because you used:
"optimize": 1
in your setup.py. That may remove the docstrings.
Thanks again for the pointer

Subject: Re: [Scikit-learn-general] Sklearn and PY2exe
Hello,
i recently have this kind of problem using pyinstaller (another packaging
tool.. but things should not be so different). They call this hidden imports
problem and I fixed this by adding explicit imports in the main file :
# pyinstaller hidden imports
from sklearn.utils import weight_vector
from sklearn.decomposition import PCA, FastICA from sklearn.pls import
PLSRegression
With those lines, i succeeded in making a stand-alone app that uses sklearn
(and more).
Many modules have some hidden imports problems (hidden means 'my packaging tool
do not see it'). To solve this in pyinstaller they use 'hook files' for
standard modules. One day i may try to make one... I think that sklearn
deserves to get one !
Hope it helps.
