float division by zero about btmpy

[amingjiang]

you can change code in indexDocs.py line 18 and line 28 to this :

print(' '.join(map(str, wids)), file=wf)

print('%d\t%s' % (wid, w), file=wf)

I don't know which line is this code, and i just can't exactly solve it.

sorry，i didn't put it very clearly.this code is in pvec.py line99

def normalize(self,smoother=0.0):
s = self.sum()
assert(s>=0)
K = len(self.p)
for i in range(K):
self.p[i] = (self.p[i] + smoother)/(s + K*smoother)

when i run this, self.sum=0 and self.p=0
