Well, this post might help you get it back. %whos displays the variable type plus some extra info: size, contents, etc. Built-in actions, like the jupyter-notebook:restart-kernel we bound in the earlier Modifying key bindings example, use the prefix jupyter-notebook.For actions defined in an extension, it makes sense to use the extension name as the prefix. Running asynchronous Rasa code in Jupyter Notebooks requires an extra requirement, since Jupyter Notebooks already run on event loops. Add Slide Bar To Python Function By @interact Decorator Example. $\begingroup$ @rcollyer: No, it is vulnerable because the mere creation of that symbol already hides the local one. import pandas as pd print(pd.__version__) > 0.17.1.
