Divide by zero in tICA #369

Closed kyleabeauchamp closed 10 years ago

kyleabeauchamp commented 10 years ago

I was comparing a bunch of tICA models and I saw this:

/home/kyleb/opt/lib/python2.7/site-packages/scipy/linalg/decomp.py:59: RuntimeWarning: divide by zero encountered in true_divide
  w = (alphar + _I * alphai) / beta
/home/kyleb/opt/lib/python2.7/site-packages/scipy/linalg/decomp.py:59: RuntimeWarning: invalid value encountered in true_divide
  w = (alphar + _I * alphai) / beta

I also think one of my eigenvalues is blowing up. This is very low priority, as it happened only once out of very many models. I figured I'd report it though.

Actually, maybe I had a duplicate feature.

I'm going to close this until I see it happen again.
