#### Install PyTorch
**On Linux**
If you would like to compile PyTorch with [new C++ ABI](https://gcc.gnu.org/onlinedocs/libstdc++/manual/using_dual_abi.html) enabled, then first run this command:
```bash
export _GLIBCXX_USE_CXX11_ABI=1
```
Please **note** that starting from PyTorch 2.5, the PyTorch build with XPU supports both new and old C++ ABIs. Previously, XPU only supported the new C++ ABI. If you want to compile with Intel GPU support, please follow [Intel GPU Support](#intel-gpu-support).
If you're compiling for AMD ROCm then first run this command:
```bash
# Only run this if you're compiling for ROCm
