执行bash test_mask_refine.sh config_vot.json SiamMask_VOT.pth VOT2016 0的问题

VOT2016下载并解压在data目录下，预训练模型也下载了。但是执行这个语句还存在如下问题
usage: test.py [-h] [--arch {Custom}] --config CONFIG --resume PATH [--mask]
[--refine] [--dataset {}] [-l LOG] [-v] [--save_mask] [--gt]
[--video VIDEO] [--cpu] [--debug]
test.py: error: argument --dataset: invalid choice: 'VOT2016' (choose from )

Start with test_mask_refine.sh and test.py, then inspect how config_vot.json and the VOT2016 data under data are passed to the --dataset argument. Reproduce the command with SiamMask_VOT.pth and determine why the reported dataset choices are empty. Done means the VOT2016 command accepts the dataset and proceeds past argument parsing.
