Doesn't seem to work under Linux, although, I placed the .py file in the /home/dev/.config/sublime-text-3/Packages/User folder

Do you get any warning or error in the Sublime console?
In the screenshot attached you can see some sample output from the Sublime console as reference.

It does not work , I have copied the file under - Roaming\Sublime Text 3\Packages\User , reopened sublime does not see any git blame for highlighted line . But this the plugin i was looking for . what is this path all about - ~/Library/Application\ Support/Sublime\ Text\ 3/Packages/User/ ???

Which OS are you using?
Could you share the log shown in the Sublime console to identify any errors or issues?
