This bug is known upstream: https://github.com/tensorflow/tensorflow/issues/31187 Disabling all CPU_FLAGS_X86 did not help Reproducible: Always Steps to Reproduce: 1. Own a Skylake processor 2. Attempt to compile tensorflow Actual Results: Build failed on the following: tensorflow/lite/experimental/ruy/kernel_avx512.cc:326:13: error: '_mm512_storeu_epi32' was not declared in this scope _mm512_storeu_epi32(tmp_ptr, accum_data_v[j]); ^~~~~~~~~~~~~~~~~~~ tensorflow/lite/experimental/ruy/kernel_avx512.cc:326:13: note: suggested alternative: '_mm512_store_epi32' _mm512_storeu_epi32(tmp_ptr, accum_data_v[j]); ^~~~~~~~~~~~~~~~~~~ _mm512_store_epi32 I have also seen memcpy related errors identical to the upstream report (I think a race condition determines the specific error). Expected Results: Compiled. As recommended in the upstream report, forcing #define RUY_DONOTUSEDIRECTLY_AVX512 0 fixes the issue.
Created attachment 593254 [details, diff] Patch to fix the issue After modifying the ebuild to use this patch, compilation succeeds.

Is this still an issue with >=2.4.0?
Seems like this was fixed in tf-2.1
