[uTVM] basic example is not woking

hi. thank you for your effort.

I have trouble in testing example code.

//////////////////////////(envireonments) microtvm 0.9.0 (in VirtualBox) Ubuntu 18.04.06 LTS Board nucleo_f746zg

//////////////////////////(error code) this code is not workng

https://tvm.apache.org/docs/how_to/work_with_microtvm/micro_aot.html#sphx-glr-how-to-work-with-microtvm-micro-aot-py

In this code, I just changed

from use_physical_hw = bool(os.getenv("TVM_MICRO_USE_HW"))

to use_physical_hw = True

other graph executer code is working well(next link code) https://tvm.apache.org/docs/how_to/work_with_microtvm/micro_tflite.html#sphx-glr-how-to-work-with-microtvm-micro-tflite-py
