URL: https://github.com/apache/tvm/issues/12595

   Hi, 
   I am trying to execute int8 tf lite models on x86 (my local PC). So I've 
used micro TVM and specifically the 
[example](https://tvm.apache.org/docs/how_to/work_with_microtvm/micro_tflite.html#microtvm-with-tflite)
 you have for this peruse. I run the example without any problem but when I 
tried to run tf lite int8 from tfhub an error accrued. To be more specific I 
tried modilenet and efficientnet and both of this modelhad the above error. 
   ```

     For a reason something is going wrong with  
tvm.micro.create_local_graph_executor() function.
