problems with matplotlib

[Rizky Maulana Nurhidayat]

Hi, I'm a beginner in python and astroML

I have a problem, when I tried to run some examples in kernel density, I got this

"rc() takes 1 positional argument but 2 were given"

How can I fix this?

Thanks

Hi  Rizky,

Could you please copy paste the full example you try to run, including the traceback? What versions of astroML and matplotlib are you using?

Cheers,

 Brigitta

Hi Brigitta,

I tried run the example from https://www.astroml.org/book_figures/chapter6/fig_great_wall.html#book-fig-chapter6-fig-great-wall

with traceback

---------------------------------------------------------------------------
TypeError                                 Traceback (most recent call last)
<ipython-input-42-041ffe8f6fc3> in <module>
     14 if "setup_text_plots" not in globals():
     15     from astroML.plotting import setup_text_plots
---> 16 setup_text_plots(fontsize=8, usetex=True)
     17 
     18 #------------------------------------------------------------

~/.local/lib/python3.7/site-packages/astroML/plotting/settings.py in setup_text_plots(fontsize, usetex)
     20     else:
     21         # New in mpl 3.1
---> 22         matplotlib.rc('scatter.edgecolors', 'b')
     23     matplotlib.rc('grid', linestyle=':')
     24     matplotlib.rc('errorbar', capsize=3)

TypeError: rc() takes 1 positional argument but 2 were given

I am using matplotlib with version 3.1.0 and astroML version 0.4.post1 

Best regards,

Rizky

Oh, yes indeed. This is a bug when using matplotlib >=v3.1. It has been fixed in the developer version, but hasn't yet been released (https://github.com/astroML/astroML/pull/188).

I planned to make a bugfix release in the next two weeks.

In the meantime you can either wait for the v0.4.1 release, or downgrade matplotlib to be <v3.1, or remove that one line when you run the example (the figure will be uglier, but everything else should keep working).

Cheers,
