If you install Python from Python.org installers, then the default
Python build flags, which should apply to scikit-learn too, specify to
build for both 32- and 64-bit (dual arch build). I just tried:
pip install -e .
in the scikit-learn directory, for a Python.org Python. That built
with the expected flags. Then I checked skilearn imported OK in
32-bit mode with:
arch -i386 python
>>> import sklearn
Then I ran the sklearn tests with:
arch -i386 nosetests sklearn
I got a few failures.
I believe this `arch -i386` only works as a prefix for Python.org
Python, but I'm happy to be corrected.
