Hi, TI support

     I have already generated the quantification information(min,max) using other tools. I want to generate my own Quantization Proto.

     First, I used Write Mode - Generate a prototxt file during TIDL's compilation.I noticed some values ​​were quite different, such as the bias value. 

     In  prototxt

    In  onnx

     Why is there such a big difference? How can I generate a suitable prototxt?

Best Regards
Henry
