Swin IR fails when loading from cached model due to added _ character when downloading model

[alejobrainz]

Hello. I've been experiencing difficulties when using de SwinIR 4x model. It works fine on the first run, but after the model is cached, the model will not be found and it will display the following error:

Exception: SwinIR 4x is not a known model

I fixed it on my local install by omitting the " " to "_" replacement when downloading on the swinir_model.py:

    def load_model(self, path, scale=4):
        if "http" in path:

            #  removed the .replace(" ", "_"), bit from the model_name:
            dl_name = "%s%s" % (self.model_name, ".pth")
            filename = load_file_from_url(url=path, model_dir=self.model_path, file_name=dl_name, progress=True)
