Examples in gallery display errors

Most examples in Dash gallery display the same error.
All on this page: https://plot.ly/dash/getting-started-part-2 (and many on other pages)
point out different lines that led to:
TypeError: __init__() takes exactly 1 argument (2 given)
I have upgraded plotly to 2.0.12 and all dash libraries to the last version.

Thanks for reporting @empet! I’m looking into this now.

I have a feeling that it might be do the fact that the prototype package called dash.ly that installed into the dash namespace and it may still be invoked. Could you try:

pip uninstall dash.ly
pip uninstall dash
pip uninstall dash-renderer
pip uninstall dash-html-components
pip uninstall dash-core-components
pip uninstall plotly
pip install dash==0.17.7
pip install dash-renderer==0.7.3
pip install dash-html-components==0.6.2
pip install dash-core-components==0.5.3
pip install plotly==2.0.12

Alternatively, try the installation in a fresh virtual env.

Let me know if that works!
