ValueError: num_val exceeds total identities 0

Hi,

I keep getting the below error when I try to run triplet_loss.py. The script is run as following:

python examples/triplet_loss.py -d dukemtmc -b 64 -j 2 -a resnet50 --combine-trainval --lr .0003 --logs-dir logs/triplet-loss/dukemtmc-resnet50

Traceback (most recent call last):
File "examples/triplet_loss.py", line 220, in
main(parser.parse_args())
File "examples/triplet_loss.py", line 92, in main
args.combine_trainval)
File "examples/triplet_loss.py", line 29, in get_data
dataset = datasets.create(name, root, split_id=split_id)

File "/media/newhome/open_reid_sample/examples/reid/datasets/dukemtmc.py", line 23, in init
self.load(num_val)
File "/media/newhome/open_reid_sample/examples/reid/utils/data/dataset.py", line 54, in load
.format(num))
ValueError: num_val exceeds total identities 0

Some one kindly help me out here.

Delete splis.json if you already had run the code once with some other errors, in my case it retained the previous files which were empty.
