How to check my TensorRT version

Hi,

dpkg -l | grep nvinfer

is full of ambiguity I think.

It will show the version of nvinfer API, but not the version of your tensorRT.
Last time I tried this command, and it showed the nvinfer API version was 4.0.4-1, which misled me to believe that my tensorRT’s version was 4. But it was wrong! At that moment my tensorRT’s version was 3.

This version from this commend was not the tensorRT version!!!

Be careful!!!

I am having the same problem on the Jetson TX2 at the moment.
According to the documentation, version 4.0 should be available on the TX2 with JetPack 3.3.
Any idea how I could upgrade TensorRT without flashing the Jetson again?

Yes, I actually upgraded the tensorRT from version 3 to version 4 without flashing the jetson. I just used the 3.3 Jetpack, and did not select the item for reflashing the board.
Plus, I just checked the jetpack website, seems now jetpack 4.2 also supports jetson TX2.
