Description
I'm totally new with all of this, so I'm not confident enough in my abilities to attempt to do the local fork/fix/pull process. I'm even pleasantly surprised I figured out what the problem was to begin with, haha.
It appears that a change in IPYWidgets happened after your sample dashboard project was created. The readout_format in cells 22 and 23 create the slider as:
widgets.IntSlider(value=oldindex, min=0,max=10, #len(df) - 1, step=1, description='Older:', disabled=False, continuous_update=True, orientation='horizontal', readout=False, readout_format='i', slider_color='white')
IPYWidgets throws up a TraitError.
I found the following issue on the Jupyter Widgets GIT which had a similar error reported. The previous version silently dropped the invalid "i" read_out format.
The corrected code for those cells should now be:
widgets.IntSlider(value=oldindex, min=0,max=10, #len(df) - 1, step=1, description='Older:', disabled=False, continuous_update=True, orientation='horizontal', readout=False, readout_format='', slider_color='white')
Thanks!
