Hi, thanks for your for implementing and sharing. I am wondering how the backward pass of warping layer working. As far as I am concerned, Floor() operation is nondifferentiable. Do...

when I try to use conda command to setup the environment, something wrong indicates as following: ![image](https://user-images.githubusercontent.com/26671598/53943575-57c36100-40f8-11e9-92a1-fee466a68c78.png) then I deupgrade the *libtiff* version, nothing is changed.
