[GitHub] hyxie6 opened a new issue #5433: mxnet.rnn.BucketSentenceIter has bug

hyxie6 opened a new issue #5433: mxnet.rnn.BucketSentenceIter has bug
URL: https://github.com/apache/incubator-mxnet/issues/5433
 
 
   suppose we have sentences with length [11, 12, 13, 14, 19], all <= 20, 
   and we provide two bucket keys [30, 40], 
   after we call mxnet.rnn.BucketSentenceIter will raise an
   
   > IndexError: too many indices for array
   
   this happens with the following program statement,
   `label[:, :-1] = buck[:, 1:]`
   
   because bucket with key 40 is empty
   one possible solution is to add the following program statement after line 104
   `self.data = [i for i in self.data if i]`
