Hi, I am new with vaex. But I am wondering if am I the only one here that tried using the .ipynb downloadable file from the webpage at https://vaex.io/docs/tutorial_jupyter.html and getting an error while re-running the file exactly as it is, line by line, in a local jupyter notebook?
Here is the first jupyter code cell that returns an error:
data_array_widget = df.widget.data_array(axes=[Lz_axis, E_axis], selection=[None, 'default'])
data_array_widget # being the last expression in the cell, Jupyter will 'display' the widget
which returns me this error:

I am on Windows 10, Python is 3.9 and jupyter is 6.5.4. Vaex is 4.16.0. Anything I am missing?
