tasks from BERT model cause segmentation fault
geekboood opened a new issue #4754: autotvm extract tasks from BERT model cause segmentation fault
URL: https://github.com/apache/incubator-tvm/issues/4754
Hi, I try to tune the matmul op in BERT model, but I encountered segmentation fault when I run the following line
`tasks = autotvm.task.extract_from_program(sym["main"], target=target, params=params, ops=(relay.op.nn.batch_matmul,))`
And using gdb it shows following message
`#0 0x00007fffe73872cf in tvm::relay::ExprFunctor<void (tvm::RelayExpr const&)>::VisitExpr(tvm::RelayExpr const&) () from /media/disk/DL/tvm/build/libtvm.so

I also see that this repo `https://github.com/icemelon9/bert-benchmark` provides the autotvm log for matmul on AVX2.0, so although the author didn't provide the code, tuning BERT should not have problem.
