fix for one error with BSRGAN, though it fails to work anyway #1109

        else:

            filename = path

        if not os.path.exists(filename) or filename is None:

            print("Unable to load %s from %s" % (self.model_dir, filename))

            print(f"BSRGAN: Unable to load model from {filename}", file=sys.stderr)

            return None

        print("Loading %s from %s" % (self.model_dir, filename))

        model = RRDBNet(in_nc=3, out_nc=3, nf=64, nb=23, gc=32, sf=2)  # define network

        model.load_state_dict(torch.load(filename), strict=True)

        model.eval()
