Hey Andy, Sorry, yes, by failing I mean it never finishes, and the python process dies without raising any exceptions. The shape of the data is (46196,114). Also numpy.all(numpy.isfinite(my_data)) returns True before I call transformer.fit() I'm running on python 2.7.8 numpy 1.9.1 sklearn 0.15.2

Hi Sklearn, I'm using Kernel PCA with the rbf kernel for projecting data into 3 dimensions for viewing alongside normal PCA and a stereographic projection class that I wrote myself. Both the PCA and SGP classes seem to be functioning correctly on this data set, but when I get to the .fit() method
