I wrote a bit about how to get Caffe2 (the AICamera example) to work on android 51. As you can tell from the other bits of the blog post, I think that libtorch would be neat to have, too, and while I have a quick and dirty “feasibility study” port, I think such a project would need commercial backing. If that works out, we could have libtorch on android by the end of the year.
Best regards
