在使用GPU加速你的深度学习程序时，你是否遇到过如下警告提示：

Could not load dynamic library \'libnvinfer.so.7\'; dlerror: libnvinfer.so.7: cannot open shared object file: No such file or directory; LD_LIBRARY_PATH: /usr/local/cuda-11.7/lib64:

Could not load dynamic library \'libnvinfer_plugin.so.7\'; dlerror: libnvinfer_plugin.so.7: cannot open shared object file: No such file or directory; LD_LIBRARY_PATH: /usr/local/cuda-11.7/lib64:

TF-TRT Warning: Cannot dlopen some TensorRT libraries. If you would like to use Nvidia GPU with TensorRT, please make sure the missing libraries mentioned above are installed properly.

当然，这些都是warning信息，并非错误信息。The shared libraries libnvinfer and libnvinfer_plugin are optional and required only if you are using nvidia\'s TensorRT capabilities.
