def vis(self,iteration) function, possible error

[shanenian]

in https://github.com/summerlvsong/Aggregation-Cross-Entropy/blob/master/source/models/seq_module.py#L65, should it be pred_string_set = [pred_string[i:i+self.w] for i in xrange(0, len(pred_string), self.w)] instetad of self.w*2?

please verify.

Thanks
