TensorRT missing in Jetson AGX Orin

[hasx1997]

Hi, I am new to Jetson and have just found someting strange. My jtop shows TensorRT is missing and there is no tensorrt folder under /usr/src/.

However, I do install tensorrt following the guidance here: How to install nvidia-tensorrt?
and check ‘import tensorrt’:

Any advice where and what to do so I can find /usr/src/tensorrt?

Add one installation error of libnvinfer-samples. Not sure whether this is why I fail to find tensorrt folder.

Hi,

Could you try to install the below command:

$ sudo apt install nvidia-tensorrt
$ sudo apt install nvidia-tensorrt-dev

Thanks.

@AastaLLL

sudo apt install nvidia-tensorrt-dev

I got this output as mentioned before:

Hi,

Could you share the output of the following command with us?

dpkg-query -W tensorrt
dpkg-query -W "*nvinfer*"

Thanks.

@AastaLLL

dpkg-query -W "*nvinfer*"

It seems no package named tensorrt:

Hi,

It looks like there are many TensorRT packages installed in your environment (nvinfer6, nvinfer7, nvinfer8).
Do you mind reflashing the system and installing the TensorRT via the below command to make sure all the dependencies are as expected?

$ sudo apt install nvidia-tensorrt
$ sudo apt install nvidia-tensorrt-dev

Thanks.

Reflashing the system should be the last operation I will take. Currently, I can import and run tensorrt smoothly. The only problem I am curious about is how jtop finds TensorRT and why it shows TensorRT as MISSING.

Hi,

jtop reads the TensorRT version via dpkg -l

jtop/jtop.py

Thanks.
