Error while converting SSD into INT8 format


I am trying to deploy SSD in INT8 mode for increasing the throughput. While performing the calibration, I am encountering this error. Error is occuring in this line of code

ICudaEngine* engine = builder->buildCudaEngine( *network );

Error is as follows

ERROR: cudnnEngine.cpp (390) - Cuda Error in execute: 4

I would like to know what is this error about. How to overcome this error?
