OK, digged a bit into this. I think I know the possible cause. This is
because of the conflict of LLVM symbols(due to different versions of LLVM being
used). PyTorch also starts to ship with LLVM. To avoid the problem, we need to
do two things
- Turn on static linking of LLVM, this will directly link llvm code into
libtvm without relying on dynamic library (that creates global symbols)
- `set(USE_LLVM "/path/to/llvm-config --link-static")`
- Turn on `set(HIDE_PRIVATE_SYMBOLS ON)`. This will effectively hide the
LLVM related symbols when we load globally from pytorch.
I did a quick experiment locally and when we turn both options ON, things
are good, and there will be conflict with either option off.
