loss m_mse of MDT-S-2 is much larger than mse and the visualization of MDT-S-2 with mask_ratio 0.3 does not work

From the loss of mse and m_mse, it seems that the mask branch does not work in MDT-S-2. We also visualize the generation image and find that generated image with mask_ratio=None is normal but the image with mask_ratio=0.3 is noise.
