[hmchuong]

Dear authors,

I have created a version of CCNet that can work with Pytorch >= 1.5. Please consider adding this branch to your repo.

Thank you!

@hmchuong Thanks for your support. It could be better if you could create a pull request, then I will merge the new branch into the repo.

Can you create a new branch and then I can create a pull request to that branch?

@hmchuong Sorry for the delay. There is a new branch https://github.com/speedinghzl/CCNet/tree/pytorch-1.5.
Thanks for the PR.
