Maxine Linux Video Effects apps fail probably due to _VFX_MODELS and _VFX_SHARE unset

Hi, everyone

I am trying to use the Maxine Video Effects SDK. I think I could successfully build it but when I tried to run ./run_upscalepipeline.sh, I could not run the sample app with the error below:

❯ ./run_upscalepipeline.sh
Error: Error while loading the TRT model
Error: Error while loading the TRT model

I looked into the .sh file and thought that _VFX_MODELS and _VFX_SHARE would provide the clue to a potential cause of the error. And I got the following echo results:

❯ echo $_VFX_MODELS

❯ echo $_VFX_SHARE

So, they were not set. I searched how to set those env variables but could not find what values I should pass to them. Does any body know how to set the variables? Plus, does anyone know the unset variables are the actual cause of the issue?

My machine is:
OS: Ubuntu 22.04
GPU: RTX 4070 Ti (12GB)
CUDA: 11.8
cudnn: 8.6.0
TensorRT: 8.5.1.7

Thanks in advance!
