about trainset

[turboLIU]

the pretrained_model in chechpoint is trained only by DIV2K training data? or there is another trainset? when I train a new model(scale=2), the performance is not as good as the chekpointmodel(scale=3) you offered, so is there dataset problem ? or it should be less performance?

@turboLIU I trained the model only by DIV2K training data. While the pretrained_model in checkpoint was trained with the option --matlab_bicubic=True. There is some difference in the implement of bicubic interpolation between opencv and matlab, that may cause different results.
