Plan to migrate to libtorch 1.2.0?

[huangenyan]

Regarding to my previous issue #19 , I find it is a bug in libtorch 1.0.1 and the bug disappears when using libtorch 1.2.0 in my little demo.
Do you have any plan to migrate the code to libtorch 1.2.0? Currently the code can't compile using libtorch-1.2.0 due to the API changes.
I'll work on this anyway, and I'm willing to submit a PR in the future. Just wonder do you have any work in progress so we can prevent some redundant work.

Feel free to create a PR for the migration, I will be very glad for this kind of work. I don't have enough time to make the migration to the new version by myself now.
