Kaldi 测试报错：utils/split_scp.pl: Refusing to split data because number of speakers 2 is less than the

新建了一个文件夹robin存放两个人的音频数据（共2x10条wav音频）做测试，运行./test_cos.sh ~/kaldi/egs/sre16/v2/robin/sub_TIMIT_test
在最后报错：sid/compute_vad_decision.sh: moving data_test/vad.scp to data_test/.backup utils/split_scp.pl: Refusing to split data because number of speakers 2 is less than the number of output .scp files 4
测试到底是如何测试的？至少需要4个人的数据？

再加入所有人（168）的数据，继续试试——还是报错：utils/split_scp.pl: Refusing to split data because number of speakers 2 is less than the number of output .scp files 4

可能是数据存放的位置有严格要求，就移动文件至~/kaldi/data/目录下。

依旧报错。
仔细按照报错的原因进入~/kaldi/egs/sre16/v2/steps去修改make_mfcc.sh里的nj参数：由nj=4改为nj=1，依旧报错：

steps/make_mfcc.sh: Succeeded creating MFCC features for data_test
sid/compute_vad_decision.sh --nj 4 --cmd run.pl data_test exp/make_vad_test mfcc_test
utils/split_scp.pl: Refusing to split data because number of speakers 2 is less than the number of output .scp files 4

后来得知，脚本make_mfcc.sh里面默认的参数可以不用去管，直接去修改当时./extract_xvectors.sh ~/kaldi/data/TIMIT_test exp/xvector_test操作中的extract_xvectors.sh即可：

#!/bin/bash
if [ $# != 2 ]; then
  echo "Usage: $0 <data-path>"
  echo " $0 ~/kaldi/data/TIMIT_test exp/xvector_T
