TypeError: unsupported operand type(s) for *: 'float' and 'collections.OrderedDict' error when executing net_interp.py

[aldogan17]

I trained PSNR_x4 and ESRGAN_x4 models for my custom data.
However, when I am trying to interpolate those two I am getting this error:
TypeError: unsupported operand type(s) for *: 'float' and 'collections.OrderedDict' error.
I also tried your models you provided in your google drive in the same script and it worked.
Why are my custom models not working?

Thanks.
