Thank you for the reply. Actually, the problem was I didn’t link the libraries properly. Now it works well.

Hello, I have a worry.

I am currently working on a project which involves applying DNN for control. I already constructed my network and I generated the TRT engine using tensorrt c++ api from the onnx file successfully. The network is made up of 2 inputs and 1 output. All inputs are data from sensors (force, position). The model performs well during the training and testing phase. My question is, how do I point the sensors to the input tensor for real-time inferencing? I will be grateful if you can help. I have been struggling with this for a long time now. All the examples I found only are all about images.

Also, any related code will be appreciated.

Thank you

Hi,
Please refer to the below link for Sample guide.

Refer to the installation steps from the link if in case you are missing on anything

However suggested approach is to use TRT NGC containers to avoid any system dependency related issues.

In order to run python sample, make sure TRT python packages are installed while using NGC container.
/opt/tensorrt/python/python_setup.sh

In case, if you are trying to run custom model, please share your model and script with us, so that we can assist you better.
Thanks!
