Why trt model returns bunch of Nan values?

Hi,
I am transferring my onnx model to trt model, after testing the outputs of the models i found that trtmodels returns plenty of NaN values.

Here are the outputs from both models. The part values are fine, but I still got plenty of NaN values.

Here is the command i used to transferring model:

./trtexec --onnx=sample_test_fixed_batch_2.onnx --saveEngine=sample_test_fixed_batch_2.trt --workspace=4096 --fp16 --verbose

I also uploaded both of the models
sample_test_fixed_batch_2.onnx (4.0 MB)
sample_test_fixed_batch_2.trt (3.1 MB)

Dear @QQQQ,
Could you share the jetpack version and used python code snippet for reproduce on our end.

HI @SivaRamaKrishnaNV
Jetpack 4.4 and attach is the code
nvidia_sample.py (4.9 KB)

Dear @QQQQ,
Is it possible to test on latest Jetpack release and confirm?

No, i haven’t tried it on jep 4.6 , since all the other service all build based on 4.4

Please try with the latest version. Thanks
