🐛 Describe the bug

Hello

I tried to build PyTorch from source in the git. I followed the installation process in README.md.

The following is the steps I took.

git submodule sync
git submodule update --init --recursive

python3 -m venv .venv
source .venv/bin/activate
python3 -m pip install --upgrade pip
pip install --group dev

export USE_CUDA=0
export USE_ROCM=0
export USE_XPU=0
export CMAKE_PREFIX_PATH="${VIRTUAL_ENV}:${CMAKE_PREFIX_PATH}"
python -m pip install --no-build-isolation -v -e .

But then, I get the following error and the build process stops.

[2629/5804] Building CXX object caffe2/CMakeFiles/torch_cpu.dir/__/aten/src/ATen/native/cpu/SortingKernel.cpp.SVE256.cpp.o

My environment is x86 CPU and Linux Ubuntu distro.

I am planning to contribute to the compiler of the project.

Thanks.

Sincerely, Yeongu

extent analysis

TL;DR

The most likely fix is to investigate and resolve the compilation error in the PyTorch build process, potentially related to the C++ compilation of SortingKernel.cpp.SVE256.cpp.o.

Guidance

Verify that the build environment meets all the requirements specified in the PyTorch README.md, including the necessary dependencies and compiler versions.
Check the C++ compiler version and ensure it is compatible with the PyTorch build process, as the error occurs during the compilation of a C++ object.
Investigate the specific error message subcommand failed and the compilation of SortingKernel.cpp.SVE256.cpp.o to identify the root cause of the issue.
Consider checking the PyTorch repository's issues or discussion forums for similar build errors on x86 CPU and Linux Ubuntu distro.

Example

No specific code snippet can be provided without further information on the compilation error.

Notes

The error message suggests that the issue is related to the build process of PyTorch, but the exact cause is unclear without more detailed output or logs.
The fact that the build process stops during the compilation of a C++ object suggests a potential issue with the C++ compiler or the code being compiled.

Recommendation

Apply workaround: Investigate and resolve the compilation error, potentially by updating the C++ compiler or modifying the build process to skip the problematic object file, as the issue is likely specific to the build environment or the PyTorch code.
