Hi,
I think the simple answer is that almost all people answering questions are doing it in their free time and answer mostly the questions they are comfortable with. And I don’t think any of the very active people here actually use libtorch.
At least this is the reason why I don’t usually answer such question unless it is one of the few things i touched in libtorch.
Maybe @smth can give a higher level answer on this? But the day to day answer I’m sure is the one above.
