redhat enterprise linux – Tensorflow-model-server installation on centos / rhel

After hours of unsuccessful attempts, I came here.
I need to install the tensorflow-model-server on a rhel box, but the instructions are missing and manual compilation has failed.

Here are the instructions to install apt-get:

echo "deb [arch=amd64] stable tensorflow-model-server Tensorflow-model-server-universal "| sudo tee /etc/apt/sources.list.d/tensorflow-serving.list && 
curl | sudo apt-key add -

I need the equivalent yum and I do not know how.
Thank you in advance for any help.
