Error yum install pgadmin4 for Postgresql10 - Centos7

Hi,

I've encountered an error when I try to "yum install pgadmin4" for Postgresql10 on a Centos 7 server
The final error message just below :

******************************************************************
--> Finished Dependency Resolution
Error: Package: pgadmin4-web-4.20-1.rhel7.noarch (pgdg-common)
Requires: python3-psycopg2 >= 2.8
Available: python3-psycopg2-2.7.7-2.el7.x86_64 (epel)
python3-psycopg2 = 2.7.7-2.el7
You could try using --skip-broken to work around the problem
You could try running: rpm -Va --nofiles --nodigest
