Output error

[love-whut]

Hello, I encountered an error after testing a single image using your weights. The terminal output is as follows:

{
    "ckpt_path": "DSRNet-main/checkpoint/DSRNet/DSRNet_x4_600000.pth",
    "cuda": false,
    "group": 1,
    "model": "dsrnet",
    "sample_dir": "DSRNet-main/results/*",
    "scale": 4,
    "shave": 20,
    "test_data_dir": "/root/DSRNet-main/dataset/*.jpg"
}
0 0

What does0 0mean? Also, there is no image output.
