Infinity scale in calibration cache file

[liming312]

Hello,

Thanks for this great repo. I used the provided script to convert a searched network (onnx model) to int8 model with int8 calibration. The onnx model works fine but the output of trt engine is wrong. When I check the calibration cache file, I found many of the quantization scales are "Infinity" and the others are very large. I converted the cache file to json file, it looks as the attached image below. Any hint is very appreciated.
