Plugin istallation problem qBittorrent

[teicang]

Hi, I just tryed to install the qBittorrent APP.
After installation I tryed to load a search plugin following the instruction indicate to this url
" You can get new search engine plugins here: http://plugins.qbittorrent.org"
I copy a link of several plugin like :
https://raw.githubusercontent.com/nindo ... /anidex.py
https://raw.githubusercontent.com/josee ... torrent.py

but when I push Ok nothing happen....I read we need python app installed , so I installed it from the app market, version 3.6 ... but nothing changed.
my TOS ver is 4.2.40
NAS F2-422

What I can do ?
thx
