try to run the model with pre-trained file but get error

[tomcan2015]

With the code:
device = torch.device(args.device)
net = SPAN(3, 3, upscale=2, feature_channels=48).to(device)
loaded = torch.load(args.model_file, map_location=device)
net.load_state_dict(loaded, strict=True)

I got this error when loading the spanx2_ch48.pth file:
File "/home/amd/anaconda3/envs/SPAN/lib/python3.9/site-packages/torch/nn/modules/module.py", line 2189, in load_state_dict
raise RuntimeError('Error(s) in loading state_dict for {}:\n\t{}'.format(

Unexpected key(s) in state_dict: "params", "params_ema".

any idea?

loaded = torch.load(args.model_file)['params']
instead of:
loaded = torch.load(args.model_file, map_location=device)
can fix the problem.
The input/output tensors has data range 0~1.

Hello!How to get the pre-train modle? I find the Google Driver link is error.
