if batch_size is modified, the accuracy after quantization will change，no modification, the accuracy rate will not change.


If MinMax observers are used, we do not expect the ordering or batch size of the calibration data to matter, as long as the same dataset gets seen via calibration. One thing to look into would be whether the way the evaluation score is measured depends on batch size, and if you are feeding exactly the same set of images through.
