According to [GPU support | TensorFlow](https://www.tensorflow.org/install/gpu), I should install TensorRT 6.0. However, looking at [Documentation Archives :: NVIDIA Deep Learning TensorRT Documentation](https://docs.nvidia.com/deeplearning/sdk/tensorrt-archived/tensorrt-601/tensorrt-support-matrix/index.html), the most recent version of CUDA that TensorRT 6.0 supports is 10.2, yet the former web page says I should install CUDA 11.2. According to [Documentation Archives :: NVIDIA Deep Learning TensorRT Documentation](https://docs.nvidia.com/deeplearning/tensorrt/archives/index.html), the oldest version of TensorRT that supports CUDA 11.2 is 7.2.2.

My question is, which version of TensorRT should I install? Should I install version 6.0, which is most likely not compatible with CUDA 11.2, or should I install a later version of TensorRT, which might not be compatible with TensorFlow 2.5.0? If so, which one?
