When I ran C++ inference script with quantized models, there always have a type inconsistent issue. Also current C++ script didn't support performance benchmark for int8/fp32 models which is not aligned with Python implementation.

Minimum reproducible example
You can refer to this README to run C++ inference. Quantized models can be generated according to this flow .
Steps to reproduce
When you have already built inception_inference and prepared the quantized model, you can run ./inception_inference --symbol "./model/mobilenet1.0-quantized-5batches-naive-symbol.json" --params "./model/mobilenet1.0-quantized-0000.params" --mean "./model/mean_224.nd" --synset "./model/synset.txt" --image "./model/dog.jpg" to reproduce the issue.
What have you tried to solve it?
This PR was already filed to fix the above type inconsistent error.
We are also going to improve the performance benchmark of C++ inference in the future PR.
