Hi there,


Sklearn website has been down for couple of days. Please look into it.


I reside in Pakistan, Karachi city.





Kind regards,

Hi,
If I remember correctly, scikit-learn.org is hosted on GitHub Pages (so the
maintainers don't have control over downtime and issues like the one you're
having). Can you connect to GitHub, or any site on GitHub Pages?

Thanks
Nelson

I have a set of feature vectors associated with binary class labels,
each of which has about 40,000 features. I can train a random forest
classifier in sklearn which works well. I would however like to see
the most important features.

I tried simply printing out forest.feature_importances_ but this takes
about 1 second per feature making about 40,000 seconds overall. This
is much much longer than the time needed to train the classifier in
the first place?

Is there a more efficient way to find out which features are most important?
