Error when running walkthrough.ipynb

The code meets a problem when calculating 'Mean Squared Displacement of Individal Probes'. It says ''particle' is both an index level and a column label, which is ambiguous.'

I have the same problem, do you found any solution for this?

[YNChen-2020]

This is because I both have 'particle' for the row name and 'particle' for the column name, see my figure in the question. If you change one of the names, it would be fine to run the code
