How to train MDSR?

[pzq-xjtu]

I use the command python main.py --template MDSR --model MDSR --scale 2+3+4 --save MDSR_baseline --reset --save_models in demo.sh

But this model only train X2 model, the performance of X3 and X4 model is very poor! Why?
The PSNR in X2model become better and better, but X3 X4 model change little.
thank you!
