[yt-users] how to remove (yt-x86_64) prefix?

[Tianyu Liu]

Dear forum,
I'm a new user (yt age: 1 day).Since the file [install_dir]/bin/activate 
was sourced, I have seen``(yt-x86_64)'' prepended to every single line 
of my bash shell. May Iknow how to remove it?Thanks.

/The rusted chains of prison moons are shattered by the sun.
I walk a road, horizons change, the tournament's begun.
The purple piper plays his tune, the choir softly sing;
Three lullabies in an ancient tongue, for the court of the crimson king.
