dear all,
similar to problem in numpy here
<http://stackoverflow.com/questions/26248654/numpy-return-0-with-divide-by-zero>
if element wise divide in theano , are there corresponding function in
theano as this answer in numpy ?
numpy answer:
import numpy as np
a = np.array([0,0,1,1,2], dtype='float')
b = np.array([0,1,0,1,3], dtype='float')
with np.errstate(divide='ignore', invalid='ignore'):
c = np.true_divide(a,b)
c[c == np.inf] = 0
c = np.nan_to_num(c)
print('c: {0}'.format(c))
Output:
c: [ 0. 0. 0. 1. 0.66666667]
how to process inf and nan problem when 0/0 or 1/0 problem in theano??
thanks
