Hi, i built TVM from master(0.7.1) and mxnet 1.6.0 mkl.It seemed i did not encounter any problem in this process. after the building, i got three .so files under tvm/lib: libtvm_runtime.so, libtvm.so,libtopi.so. However, when i was using this script to do the bert optimization https://gist.github.com/icemelon9/860d3d2c9566d6f69fa8112840dd95c1
i got this error: MXNet latency for batch 1 and seq length 128: 81.21 ms Cannot find config for target=llvm -keys=cpu -libs=cblas -mcpu=skylake-avx512, workload=(‘dense_cblas.x86’, (‘TENSOR’, (1, 768), ‘float32’), (‘TENSOR’, (2, 768), ‘float32’), None, ‘float32’). A fallback configuration is used, which may bring great performance regression.
