So many bugs,please give up coding! I almost fixed the code here and there

[jihunchoi]

How about giving up ranting and starting to think what's README for? 😃

ok i apologize for that ,and i wanna sugest you use following code instead of yours , It will spped up at least 5 times than yours

def pack_for_rnn_seq(self,inputs, lengths):
    """
    :param inputs: [T * B * D]
    :param lengths:  [B]
    :return:
    """
    _, sorted_index = lengths.sort(descending = True)

    '''
        Reverse to decreasing order
    '''

    s_inputs = inputs.permute(1,0,2)[sorted_index].permute(1,0,2)
    lengths_list = []
    reverse_indices = [0] * lengths.size(0)
    for j, i in enumerate(sorted_index):
        lengths_list.append(lengths[i].item())
        reverse_indices[i] = j
    packed_seq = pack_padded_sequence(s_inputs,lengths_list)

    return packed_seq, reverse_indices

def unpack_from_rnn_seq(self,packed_seq, reverse_indices,max_len):
    unpacked_seq, _ = pad_packed_sequence(packed_seq,total_length=max_len)
    s_inputs_list = []
    return  unpacked_seq.permute(1,0,2)[reverse_indices].permute(1,0,2)
