After training, objects cannot be detected

[liuqiang1227]

I used train.py for training after creating a dataset in NDDS, but I was unable to detect my own model。
This is my JSON

This is the file generated after my training

This is my terminal command
python3 train.py --data /home/a/TestCapturer --object yepian --outf yepian --gpuids 0 --epochs 120 --loginterval 1 --batchsize 16
