Re: [Mrfilter-users] Fwd: Failed Startup (Fedora 17)

[Joe M. <joe...@gm...>]

Actually, I just found that this code executes several times before causing
the error.

> /usr/lib/python2.7/site-packages/mrfilter/mrfilter_util.py(225)set()
-> if np.isinf(value) == True or np.isnan(value) == True:
(Pdb) p value
1
(Pdb) c

    pdb.set_trace()
NotImplementedError: Not implemented for this type

On the fourth iteration, value equals 'butter', so the error occurs.  A
comment directly above that line sounds very relevant:

      #Here we must compare to True instead of doing 'if np.isinf(...)'
      #because np.isinf(string) will return NotImplemented, which tests
      #as true
