TensorFlow stuck in infinite loop when executed with NVBit.

[JueonPark]

I am using NVBit 1.5.3 to get the trace of TensorFlow application. When I run the application without NVBit, the TensorFlow application runs fine. However, when I run the application with NVBIt, the application is stuck in autotuning.

The running command is as the following:
LD_PRELOAD=$TRACER_TOOL python run.py --batch_size 1024 --num_examples 2000

The error message ends as the following:

The application is stuck on parameter autotuning. Even if I disabled the parameter autotuning, the application is stuck and does not end.

I am using cuda 10.1 with cudnn 7.6.4. I am using RTX 2080Ti GPU with Intel Xeon Gold CPU.

I am sorry for submitting issue specified to TF. Thank you.
