I need help with installation for python 3.6 please

[net1media]

Could not find a version that satisfies the requirement qt5 (from versions: )
No matching distribution found for qt5

---

I am trying to install PyQt5 and Qt5 on python 3 only for development use, so I created the virtualenv and activate it, Installed PyQt5 and other module but can't install Qt5 packages, It should be included with PyQt5 but when I run

rpm -ql qt

it gives me the following error

package qt is not installed

and if I run

pip3.6 install qt5

or

sudo pip3.6 install qt5

it gives the The error:

Could not find a version that satisfies the requirement qt5 (from versions: )
No matching distribution found for qt5

when I use

yum install qt5

it says that I have to be root, when I go to root it gives the following:

Loaded plugins: fastestmirror, langpacks
Loading mirror speeds from cached hostfile
* base: mirror.vorboss.net
* epel: http://www.mirrorservice.org
* extras: mirror.vorboss.net
* ius: mirror.amsiohosting.net
* updates: centos.serverspace.co.uk
No package qt5 available.
Error: Nothing to do

Is qt5 included with PyQt5 package or I need to download it from source? If I need to download it, How can I make it install for python 3 only (Which folder in the virtualenv should I put the downloaded file into before I run it).

Thanks
