results.pkl is empty

[hytim]

I run the inference command below

python tools/test.py configs/ReDet/ReDet_re50_refpn_1x_dota15.py     work_dirs/ReDet_re50_refpn_1x_dota15/ReDet_re50_refpn_1x_dota15-7f2d6dda.pth --out work_dirs/ReDet_re50_refpn_1x_dota15/results.pkl

The output is as follows:

completed: 0, elapsed: 0s
writing results to work_dirs/ReDet_re50_refpn_1x_dota15/results.pkl

However, the results.pkl is empty when I load the file.

My test file is in ReDet/data/dota15_1024/test1024/ .

Thanks very much if someone can help me.

I further debug the test.py. The problem may result from len(data_loader) == 0.
I don't know what leads to it.
