Description
The example data_loader.py file used the fake data.
I want to know how to write the file to send image files data to Polygraphy to calibrate the model and improve the accuracy.
Such as the axis, the data range, and so on.
The axis is image_num, image_channel, height, width or the other?
The data range is [0, 1] or [0, 255]? It should be the same as the pth model input or be stricted to a fixed range?
Thank you for any suggestions or help.

Research direction
Start with tools/Polygraphy/examples/cli/convert/01_int8_calibration_in_tensorrt/data_loader.py and inspect how its fake calibration data is passed to Polygraphy. Document how image files should be supplied, including the expected axis order and data range relative to the model input; done means the example answers those questions for real image calibration data.
