Virtual environment

[AtomsForPeace]

Hey, I was looking at the install.sh file and see that it doesn't use a virtualenv. I think it would be better to do so in case the requirements conflict with requirements elsewhere. I can open a pull request for this if so desired. I suppose it could be located under /etc/chocolate/ or maybe you have a better suggestion?

I think the best think to do is rewrite all the install, so the .sh, and all the docker one's, but yeah, in the next one we will use venv. Thanks for the comment
