i use gdb bt to debug, the error is: Thread 1 “python3” received signal SIGSEGV, Segmentation fault. 0x00007ff22169acd4 in llvm::EVT::getExtendedVectorNumElements() const () from /home/tvm/build/libtvm.so
I also test the llvm9.0 and 10.0 and meet the same problem, how to slove this Segmentation fault?
