Not sure exactly sure how to fix the following attribute error:
AttributeError: 'AxesSubplot' object has no attribute 'add_axes'
The offending problem seems to be linked to the way I have set up my plot:
gridspec_layout = gridspec.GridSpec(3,3)
pyplot_2 = fig.add_subplot(gridspec_layout[2])
ax = WCSAxes(fig, [0.1, 0.1, 0.8, 0.8], wcs=wcs)
pyplot_2.add_axes(ax)
Does anybody know how to solve this? Many thanks.
There's not much details to go on in your question but I'll wager a guess.
The error is pretty self-explanatory. You can't add_axes to pyplot_2 because pyplot_2 is a matplotlib.axes.AxesSubplot object and they don't have an add_axes method defined.
Only matplotlib.figure.Figure objects have add_axes method defined on them.
From what I got from a short browse through the WCSAxes official documentation their recommended approach would be:
wcs = astropy.wcs.WCS(....)
fig = matplotlib.pyplot.figure()
pyplot_2 = fig.add_subplot(gridspec_layout[2], projection=wcs)
You now need to use set_prop_cycle i.e. ax.set_prop_cycle(color=['red', 'green', 'blue'])
Axes.set_color_cycle(clist) was depreciated since, version 1.5.

I did a conda update pandas and the error went away. Nothing else I could find worked.
Mine was a slightly different flavor of this error (not 'add_axes'). It happened when I was trying to use pandas.DataFrame.plot within matplotlib subplots.
I was on pandas 0.25.3 before and after, and a number of packages were upgraded/downgraded.
I encountered this same error several days ago on both a Macbook and a Lenovo laptop. I used Anaconda for my python installation on both computers.
This is a problem with the Matplotlib package management. So the solution for me was to remove Matplotlib and reinstall it. Then the error is gone.
Just downgrading matplotlib to an old version would help. I downgraded it to 1.4.0 and it fixed the problem.
