Cannot run sampleUffSSD for INT8 inference, Calibration failed

I’m having the same “relu2 is uniformly zero;” problem.
I forced resized data to 300x300 and check the P6 format and the error still occur.

I had the same issue with the “relu2 is uniformly zero”. I have solved it by making it calibrate on 50 batches instead of 10. Try getting more data from the COCO dataset.

@iliya.strelnikov thank you! This worked for me after upping the batches to 150 (7500 images)
