PyTorch upstream, but C++11 ABI wheels and docker images have better lazy tensor
tracing performance.

To install C++11 ABI flavored 2.6 wheels (Python 3.10 example):

```sh
pip install torch==2.6.0+cpu.cxx11.abi torch_xla[tpu]==2.6.0+cxx11 \
pip install torch==2.6.0+cpu.cxx11.abi \
https://storage.googleapis.com/pytorch-xla-releases/wheels/tpuvm/torch_xla-2.6.0%2Bcxx11-cp310-cp310-manylinux_2_28_x86_64.whl \
'torch_xla[tpu]' \

-f https://storage.googleapis.com/libtpu-wheels/index.html \
-f https://download.pytorch.org/whl/torch
```

The above command works for Python 3.10. We additionally have Python 3.9 and 3.11
wheels:

- 3.9: https://storage.googleapis.com/pytorch-xla-releases/wheels/tpuvm/torch_xla-2.6.0%2Bcxx11-cp39-cp39-manylinux_2_28_x86_64.whl
