I have an error like this when I compile the RISCV backend in tvm.

Segmentation fault(core dumped)

The code I wrote is as follows

n=16 target=‘llvm -target=riscv64’ A = tvm.placeholder((n, ), name=‘A’) B = tvm.placeholder((n, ), name=‘B’) C = tvm.compute((n, ),lambda i: A[i]+B[i], name=‘C’) s=tvm.create_schedule(C.op) func=tvm.build(s,[A,B],target=target,name=‘si’)

How should I solve this problem?I didn’t add any features to tvm, is it that I should do something more?
