Int8 calibration


I’m trying to quantify my pytorch model as int8,but Code error:
Calibration failure occurred with no scaling factors detected. This could be due to no int8 calibrator or insufficient custom scales for network layers. Please see int8 sample to setup calibration correctly. Builder failed while configuring INT8 mode.
