Hi everyone, I'm actually not convinced about the new layout (sorry Andy :( ). I should also say, I'm not convinced about panda's website. The menu is, I think, quite confusing. Overall, I think there are two many links which may refer to the same thing: the difference between "installation", "g

[Scikit-learn-general] Sprint in Paris

Hi guys, It turns out that, despite the framadates attempts (thanks to everyone to have filled these up!), it's going to be tough to organize a sprint in April or May... The best week happens to be just before the NIPS deadline, and the second best week is too short for us to raise money for the

Hello everyone, It's been a while since the last international sprint, so Alex, Gaël and I were discussing about when, where and how to organize a sprint. It seems hard for us to organize one at NIPS (because of the costs), or at EuroScipy (the schedule is already tight at this period). So we dec
