PyTorch Frontend: C++11 vs Python

PyTorch has just released the C++11 front-end, and I am in a struggle answering these questions:

  • Does it worth shifting from the Python front-end to the C++'s (concerning performance)?
  • Is the development time going to be much more using the C++ front-end than the Python’s?
  • When should I use it?
  • What is the trade-off?
