Can't reproduce nice results for RealSR dataset

Hi thanks for the nice work, I am using your test.py code to upsample center cropped 256x256 images from the RealSR dataset and using the evaluation suite of OSEDiff, which is also used in consecutive works like TSD-SR etc. However the results are too far away from what I expected. I follow the test code as it is only change captioner to empty what might be wrong.
