Error loading dependencies

[yesterdog]

I tried this https://github.com/plotly/dash-recipes/blob/master/dash-tabs-with-dropdown.py and got an error about usage of variable 'tabs' with in dcc.Tabs. I changed it to 'children' and ran it and then received the following error.

This is my command prompt window

I am using
dash == 0.27.0
dash_core_components == 0.30.2
dash_html_components == 0.13.2

Do I have to use specific version of libraries or something?
