[Bug] Can't run prequantized tflite model through MicroTVM

[zhiwei-dong]

Expected behavior

Thank for your great works on microTVM, I try to run MCUNet model, in here .
I followed this tutorial. When I use the tutorial model, every thing is ok, but when I use above mcunet model, I encounter RPCError.

Actual behavior

(microtvm-3BvVWFka-py3.6) vagrant@microtvm:/Users/zhiwei.dong/test/tvm$ tvmc run \

     --device micro \
     project \
     --project-option zephyr_board=qemu_x86 \
     --fill-mode ones \
     --print-top 4
