Error when running `pummel featurize SORT_DIR`

[Lizette-Lemus]

When I ran pummel featurize SORT_DIR I received the next error:

Picking bandwidth by median heuristic...Traceback (most recent call last):
  File "./pummel", line 5, in <module>

    raise Exception('Data must be 1-dimensional')
Exception: Data must be 1-dimensional

I found a work around by adding .values to the code in lines 49 and 50 of featurize.py

   reals[:] -= stats['real_means'][real_feats].values
    reals[:] /= stats['real_stds'][real_feats].values

Is this a good way to fix this?

Huh, weird. I'll try to look into this later today.

It looks like you're probably using an old version of pandas, which likely caused the problem. That's a reasonable fix, which I've put into the new pummeler 0.2.3 release, but let me know if you hit other errors elsewhere....
