With the release of matplotlib 3.8, the following tests are failing see here.

Also adding the following warning:

    for level, cset in zip(levels, contour_set.collections):

I will try to fix these tests later this week. But for now I will just pin.

With the new dev release of 1.18, we no longer support py2js, which were used for {x,y}formatters when the input was a function. I have removed it for now in the notebook.
