Pip install bokeh installs version 1.3.4

I want to install version 2.0.0 of bokeh, but doing pip install bokeh installs version 1.3.4 . Any suggestions?

import bokeh
print(bokeh.version)
1.3.4

Hi @vijay_dubey it looks like you already have Bokeh 1.3.4 installed. pip install will not replace an existing package, that is just how pip always behaves. You have to explicitly ask for a new version with pip install --upgrade
