A little problem.

When running GRACE-Harmonic-Plots.ipynb, the following error occurs. What should I do to solve it?

set the directory with GRACE/GRACE-FO data

update local data with PO.DAAC https servers

widgets = gravtk.tools.widgets() ipywidgets.VBox([ widgets.directory, widgets.update ])

---

hi @zhangyuyayaya, Right. I think ipywidgets deprecated copying widgets to new variables. I think I scrubbed out all instances of the copies in #151

thanks.
