question about run_pipeline.py

[sunj0104]

hello, I run our code on windows and vs2022 follow the guild. when I run the run_pipeline.py, I got the wrong result in log file. Do you know how to fix it, thank you very much~The log file content as follow:

Can you provide the version of clang and llvm-config?

[sunj0104]

Sure，thanks for your quick response~ clang version 18.1.8; llvm-config version 17.0.6

[kaleid-liner]

TVM is incompatible with clang 18 or llvm 18. You can use clang=17.0.6 instead.

[sunj0104]

great, it is normal now~thank you again

[kaleid-liner]

I will close the issue as resolved
