Why is acc always zero

[2151330]

I used train_softmax,py in https://github.com/deepinsight/insightface/blob/master/src/train_softmax.py
The parameters are set like this：
CUDA_VISIBLE_DEVICES='0' python -u train_softmax.py --network y1 --ckpt 2 --loss-type 4 --lr 0.00001 --emb-size 512 --per-batch-size 80 --wd 0.0000001 --data-dir /home/mi5/insightface/src/data/faces_vgg --pretrained /home/mi5/insightface/models/model-y1/model,00 --prefix ../models/MobileFaceNet/model-y1
Why is acc always zero？Can you help me?
