Something wrong of form .rec of my own data

[larsonwu0220]

I try to form .rec and .idx of my own data.
First, run im2rec.py to generate list :
python im2rec.py --list --recursive --train-ratio 1 [list folder] [images folder]

Second, run im2rec.py to generate .rec and .idx.
python im2rec.py --num-thread 4 [list folder] [images folder]

But when I read index,

imgrec = mx.recordio.MXIndexedRecordIO(args.idx_path, args.bin_path, 'r')
s = imgrec.read_idx(0)
header, _ = mx.recordio.unpack(s)

The "header" has no label value.

Where is the problem?
Thanks.

Thanks a lot for reporting this issue. Is every label in the file incorrect or just a few?
