This means that the vim you're invoking does not have the "python3" 
feature compiled into it. Indeed, in the `vim --version` output you 
include there is this:

    $vim --version
    VIM - Vi IMproved 7.4 (2013 Aug 10, compiled Dec 15 2020 16:44:08)
    Included patches: 1-207, 209-629
    Modified by <bugzilla at redhat.com>
    Compiled by <bugzilla at redhat.com>
    Huge version without GUI.  Features included (+) or not (-):
    [...]
    +cryptv          +linebreak       +python/dyn      +viminfo
    +cscope          +lispindent      -python3         +vreplace
    [...]

So you can see that "python3" has been omitted from that build.

Do a "yum search vim" and see if there is a vim variant with "python3" 
included (I haven't got a Centos host available to me). You could try 
replacing the installed vim with the python3 enabled vim if that is 
available.
