TensorFlow TensorRT Warning - Could not find TensorRT

Question

I'm encountering an issue with TensorFlow while using TensorRT. The warning message I receive is as follows:

2023-07-28 16:27:20.817724: W tensorflow/compiler/tf2tensorrt/utils/py_utils.cc:38] TF-TRT Warning: Could not find TensorRT

I have already tried installing TensorRT and its dependencies correctly on my system, but the issue persists. My setup includes TensorFlow and an NVIDIA GPU with compatible drivers.

Has anyone encountered a similar problem or has suggestions on how to resolve this? Any guidance on troubleshooting and fixing this warning would be greatly appreciated.

Thank you for your help!

First of all, if you have not installed already, try to install it via pip: pip install tensorrt

Strangely, simply installing it does not help on my side. As if the path it looks for has changed across versions. If installing does not help for you either, try:

export LD_LIBRARY_PATH=$LD_LIBRARY_PATH:<path to your python libs>/tensorrt_libs/

My bet is this will be enough. However, if you additionally run into a version compatibility issue (say *.so.7 vs *.so.8), you can circumvent in some cases by adding symlinks into the same tensorrt_libs directory.
