As I downloaded libtorch, I have two choices: Pre-cxx11 ABI and cxx11 ABI. The question is that what is the difference between them？

C++

In itself, the choice would not matter too much (I’d probably take the cxx11 ABI).
The tricky part is when combining it with other libraries:

  • Typically C++ libraries are linked with the cxx11 ABI by default.
  • The official PyTorch Python module are linked with the old pre-cxx11 ABI, so if you want to use them, you need this.
  • If you have a mix of these, you are in a real pickle. :frowning:
