Question about int8 Calibration about play_with_tensorrt HOT 5 CLOSED

This sample uses 20 image files contained here. So, 20 = 10 x 2 = CAL_BATCH_SIZE (10) x CAL_NB_BATCHES (2)

from play_with_tensorrt.

So now i know that CAL_BATCH_SIZE = number_of_ppm_images
but why CAL_NB_BATCHES = 2 and CAL_BATCH_SIZE = 10

from play_with_tensorrt.

No reason. I just set those numbers.
They can be CAL_NB_BATCHES = 4 and CAL_BATCH_SIZE = 5

from play_with_tensorrt.

Hmm im little confused so i guess i have to bruteforce a little until i find good parameters i guess? Or is there at least 1 approach i can use. Because rn i dont know what to set my parameters to or where to start. And what about CAL_SCALE? Is it just calculated when i run Calibration or is it important to set a value before that

NVIDIA Developer Forums would be an appropriate place to ask the questions. Also, I suggest reading an official sample program (sampleINT8.cpp) because I referred to this sample code.
