PyTorch CI Build Issue Request for Help

[Steven Smith]

PyTorch build and runs fine locally, but the CI consistently fails with error below. This issue has created unnecessary delays in merging new PT versions. 2023-03-18T18:24:32.7624930Z CMake Error at third_party/fbgemm/CMakeLists.txt:76 (message): 2023-03-18T18:24:32.7638400Z A compiler with AVX512 support is required. A successful build uses: :debug:build CXX='/usr/bin/clang++' … :info:build -- Performing Test C_HAS_AVX512_2 - Success … :info:build -- Performing Test CXX_HAS_AVX512_2 - Success I believe that the right compiler is set. Any suggestions, or does this complicated build fail with the CI box?
