Hi everyone working on VTA and @thierry,

I am trying to load Pytorch model and see how the VTA instruction is generated.
Here is the notebook based on the 
[tutorial](https://tvm.apache.org/docs/vta/tutorials/frontend/deploy_classification.html#sphx-glr-download-vta-tutorials-frontend-deploy-classification-py)
  and [this 
discussion](https://discuss.tvm.apache.org/t/pytorch-quantization-error-during-quantization/7167).

- https://gist.github.com/insop/18aaab92d48061c6c0e440be0bd83733


However, at the end I don't see any VTA instruction is running when I tried 
`sim_stats = simulator.stats()`.

```
Execution statistics:
        inp_load_nbytes :                0
        wgt_load_nbytes :                0
        acc_load_nbytes :                0
        uop_load_nbytes :                0
        out_store_nbytes:                0
        gemm_counter    :                0
        alu_counter     :                0

```

Based on MxNet tutorial mentioned above, I am don't see why there is no VTA 
instruction is issued ( also enabled `debug_flag_` and don't see debug 
instruction is printed either).

Can anyone help?

Thank you,

ISS
