Fontsize/Label error in pdp.pdp_interact_plot when contour = True

[jsga]

This command works fine and produces the expected results:

fig, axes = pdp.pdp_interact_plot(
    pdp_interact_out = inter1,
    feature_names=['NOx', 'NO_2'],
    plot_type='grid'
)

However, changing only plot_type to contour gives an error related to the labels and the font size. The figure appears label-less at the bottom after this error. Any guess or help is appreciated.

Thank you in advance. Awesome library by the way!

Re-running the whole notebook seems to fix it :S Thanks anyways

It seems the error is gone when using a version of matplotlib 2.x.
The error pops up with version 3.0

Any updates on this issue?
Is the only solution downgrading matplotlib?

Thanks

[r-ichi]

Yeah...any updates on this issue? :/
