Python Install / Script Error Correction

I'm using this script: [login to view URL] On a ubuntu 16.04 system. It is used to record webcam shows from the website chaturbate. It is double/triple and sometimes 4X the same video... or it will start a recording of the stream video and then start again 3 mintues later (example) and record the same video twice, three or four times. I believe this is a python install issue. I have python2.7, python3.5 and python3.6 installed on the server. I have read the removing and installing python can be difficult unless you know what you are doing because so many parts of the server requires it. I need someone to remove python3.5 and python3.6 and install python3.5 along with livestreamer, bs4, lxml, gevent. I believe python2.7 is needed by the OS Ubuntu, but if not required it is ok to uninstall it as well. I also use XRDP and XFCE Template to connect to the servers desktop, this needs to continue to work.
