tensorrt 5.1.5 install ERROR on centos 7

I installed cuda 10.0 on my machine, and I added the lib64 to LD_LIBRARY_PATH.
I installed tensorrt 5.1.5 following the offical steps https://docs.nvidia.com/deeplearning/sdk/tensorrt-install-guide/index.html#installing-rpm,,but it reported errors after I did “yum install tensorrt”:

yum install tensorrt

    You could try using --skip-broken to work around the problem

Could anyone help me ?
