Hi @dannisliang,

Can you please share the exact instructions or commands you are following from our documentation here?

Also, can you confirm whether you are using Bazel 7.6.1? This version is not currently supported. The supported version is Bazel 6.5.0, as specified here.

Additionally, were you able to successfully build the Hello World example from the same documentation?

Please provide the complete error log you’re encountering so we can assist further.

Thank you!!

This is unrelated to issue (#5975). After changing the Bazel version to 6.5.0, the issue (#5975) seems to no longer occur. However, the following errors still persist: ERROR: C:/users/_bazel_admin/vrlotbeo/external/XNNPACK/BUILD.bazel:669:36: Compiling src/qs8-qc8w-igemm/gen/qs8-qc8w-igemm-5x8c8-minmax-fp32-avxvnniint8-prfm.c failed: (Exit 2): cl.exe failed: error executing command (from target @XNNPACK//:avxvnniint8_prod_microkernels) D:\program files\Microsoft Visual Studio\2022\Enterprise\VC\Tools\MSVC\14.29.30133\bin\HostX64\x64\cl.exe /nologo /DCOMPILER_MSVC /DNOMINMAX /D_WIN32_WINNT=0x0601 /D_CRT_SECURE_NO_DEPRECATE ...

I'm trying to solve this issue, and I realized the _mm256_dpbusd_avx_epi32 function is not enabled. and It seems to be an issue with XNNPACK itself.

I updated XNNPACK to the latest commit, but another error occured in a different module.

C:\users\me\_bazel_me\kwqutj5l\execroot\mediapipe\external\pthreadpool\src\threadpool-atomics.h(14): fatal error C1083: Cannot open include file: 'stdatomic.h': No such file or directory

it seems the Mediapipe project does not check the Windows build.

The root cause of the original error is the wrong OpenCV version specified in the documentation. Here is the issue with explanation: https://github.com/google-ai-edge/mediapipe/issues/5876. I prepared the documentation fix, which has been awaiting code review for months: https://github.com/google-ai-edge/mediapipe/pull/5877.
