[Numpy-discussion] linux wheels coming soon

I have tested the new cp27m wheels and they seem to work great.

@Matthew I am using the:

sudo: required
dist: trusty

images mentioned here https://docs.travis-ci.com/user/ci-environment/. As
far as I can see you are doing:
sudo: false
dist: trusty

I had no idea such an image exist since it's not documented on

Anyway your tests runs with python 2.7.9 where as the sudo: requires ships
python 2.7.10 so it's clearly a different python version:

@Olivier Grisel this only applies to Travis's own home build versions of
python 2.7 on the Trusty running on google compute engine.
It ships it's own prebuild python version. I don't have any issues with the
stock versions on Ubuntu which pip tells me are indeed cp27mu.

It seems like the new cp27m wheels works as expected. Thanks a lot

python -c "from pip import pep425tags;
print(pep425tags.have_compatible_glibc(2, 5));
pip install --timeout=60 --no-index --trusted-host "
--find-links  "
numpy scipy --upgrade
results in:

    Uninstalling numpy-1.10.1:

Successfully installed numpy-1.11.0 scipy-0.17.0
And all my tests pass as expected.
Thanks a lot for all the work.
