HOSTFILE没有多个机器的话可以写localhost吧，运行之后提示的是Unable to find hostfile，will proceed with training with local resources only 但是那个DATA_PATH应该给什么格式的路径啊，比如json，csv这种可以么？

直接运行finetune_codegeex.sh的话，没有给pretrain传入valid_forward_step，valid_forward_step会默认为None，在到了eval-interval之后会报错valid_forward_step是None，NoneType不能call；应该finetune_codegeex.sh里要改成finetune_codegeex.py而不是pretrain_codegeex.py，改了之后可以正常fintune，evaluate和save checkpoint。

The input image resolution is $512\times270$ when testing 4x super-resolution inference speed. To calculate the PSNR, the input image resolution is based on the specific dataset(Set5, Set14, BSD100, Urban100).
