You didn't use a OneVsRestClassifier. SGDClassifier itself can only do multi-class, not multi-label. It needs to be GridSearchCV(OneVsRestClassifier(SGDClassifier()), ...) On 01/04/2016 02:15 AM, Startup Hire wrote: Providing the full StackTrace here:[ code in previous email] # Tuning hyper-pa

Hi Ola. Sorry for the late reply, I've been offline over the holidays. Unfortunately, there is no owner of the cross_decomposition module at the moment, which is probably the main reason it is in a not-great state. You can also have a look at https://github.com/scikit-learn/scikit-learn/issues/

Hi Sonali. Your skill-set seems great for a GSoC with scikit-learn. We have found that in recent years, we were quite limited in terms of mentoring resources. Many of the core-devs are very busy, and we already have many contributions waiting for reviews. If you are interested in working on s

Yeah, having a continuation of the download or retry would be nice, I think. PR welcome. On 12/31/2015 05:58 AM, Toasted Corn Flakes wrote: > Currently, if you interrupt check_fetch_lfw() (which downloads about 200mb of > data), the incomplete lfw-funneled.tgz stays on disk, and running it again

2016-01-04 Thread Andreas Mueller
That's really odd. scikit-learn 0.17 should definitely work with numpy 1.10. This looks more like a linker failure, so it being version dependent in numpy seems strange.. On 01/04/2016 08:00 AM, Joe Cammisa wrote: folks, just to follow up on this in case anyone else runs into the same proble

Happy new year! I think it would be cool to hear from matplotlib what their experience was. I'm not sure I'm for dropping 2.6 for the sake of dropping 2.6. What would we actually gain? There are two fixes in sklearn/utils/fixes.py that we could remove, I think. Also: what does dropping 2.6 mean?

Re: [Scikit-learn-general] BIC/AIC for Feature Selection

Yes. Each model should have defined a likelihood function which computes the BIC/AIC. In the Linear regression, with the error Normality assumption, it would be RSS/ ( n − p − 1), as far as I know. What do you think? 2016-01-02 13:39 GMT+01:00 Gael Varoquaux : > On Fri, Jan 01, 2016 at 08:41:56P

My own opinion, after reading the link in the original message in this thread, is to drop Python 2.6 support. Perhaps Python Weekly and LWN will report on this to increase visibility. As a follow-up, I'd like to point out http://www.snarky.ca/why-python-3-exists Dale Smith, Ph.D. Data Scientis

For what it’s worth, pandas is dropping 3.3 in our next release (0.18 maybe end of this month). We’re possibly dropping 2.6 as well, but it might get one more release. -Tom > On Jan 4, 2016, at 7:28 AM, Gael Varoquaux > wrote: > > Happy new year everybody, > > As a new year resolution, I su

Happy new year everybody, As a new year resolution, I suggest that we drop Python 2.6 compatibility. For an argumentation in this favor, see http://www.snarky.ca/stop-using-python-2-6 (I don't buy everything there, but the core idea is there). For us, this will mean more usage of context manager

folks, just to follow up on this in case anyone else runs into the same problem: after much mucking around, i conclude that the issue is due to a change that has taken place in numpy between versions numpy-1.9 and numpy-1.10. in my experience, scikit-learn-0.17 cannot be successfully built agains
