I have some question about Rouge and how to train it more quickly?

[paozhuanis1]

I run these codes on Google Colab.

1. about Rouge
   I download ROUGE-1.5.5.pl from network and I just put this file under the folder without doing anything. I do not know if it works.
   just like this:(also in ./data, there is the same file)
   
   by doing this, the 'NOT FOUND" problem disappeared, but it have the new problem----"/bin/sh: 1: ./ROUGE-1.5.5.pl: Permission denied"
   

I want to know how to solve it.

2.how to train it more quickly
I did not modify any parameter, I just run "python train.py". And it takes me around 1 hour to train one epoch.
I want to kown if there is some way to change the implementation to make it quicker.

The first question is siginificant. And I would appreciate it if you can give me an early reply.
