some problem of the code

[janny]

hello,
I couldn‘t run the code of "restoration".I had this problem when I run "restoration":name 'Concat' is not defined.(the "concat" from the "skip.py").
My python and pytorch versions are 3.6 and 0.4,but i couldn't run the code successfully.Anybody know how to solve this problem?Thank you.
