xpra client

[union]

So I have xpra installed and working on the server.
The server is a centos 7.3 OS and client is centos 6.8 OS
I used command:

xpra start :100 --start-child=firefox --bind-tcp=SERVERIP:10010

I want to xforward firefox borwser to the client workstations.

on the client I installed

xpra-common-1.0.6-1.r15846.el6_8.noarch

When I run: xpra start ssh/root@SERVER IP --start-child=firefox

The error I am getting is:

Traceback (most recent call last):
  File "/usr/bin/xpra", line 3, in <module>
    from xpra.platform import init, set_default_name
ImportError: No module named xpra.platform

Do I need to do a full install of xpra on the client workstation as I have only installed the xpra-common package, which other packages do I need to install?

Install xpra as per the instructions.
