matplotlib: AttributeError: 'AxesSubplot' object has no attribute 'add_axes'
提问by
Not sure exactly sure how to fix the following attribute error:
不确定如何修复以下属性错误：
AttributeError: 'AxesSubplot' object has no attribute 'add_axes'
The offending problem seems to be linked to the way I have set up my plot:
有问题的问题似乎与我设置情节的方式有关：
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.
有谁知道如何解决这个问题？非常感谢。

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_axesto pyplot_2because pyplot_2is a matplotlib.axes.AxesSubplotobject and they don't have an add_axesmethod defined.
您的问题没有太多细节可谈，但我打赌。该错误是不言自明的。您不能这样做add_axes，pyplot_2因为它pyplot_2是一个matplotlib.axes.AxesSubplot对象并且它们没有add_axes定义方法。
Only matplotlib.figure.Figureobjects have add_axesmethod defined on them.
只有matplotlib.figure.Figure对象add_axes定义了方法。
From what I got from a short browse through the WCSAxes official documentation their recommended approach would be:
根据我从 WCSAxes 官方文档的简短浏览中得到的信息，他们推荐的方法是：
wcs = astropy.wcs.WCS(....)
fig = matplotlib.pyplot.figure()
pyplot_2 = fig.add_subplot(gridspec_layout[2], projection=wcs)

just downgrade matploblit to an old version would help. I downgrade it to 1.4.0 and it fix the problem.
将 matploblit 降级到旧版本会有所帮助。我将其降级到 1.4.0 并解决了问题。

You now need to use set_prop_cycle i.e. ax.set_prop_cycle(color=['red', 'green', 'blue'])
你现在需要使用 set_prop_cycle 即 ax.set_prop_cycle(color=['red', 'green', 'blue'])
Axes.set_color_cycle(clist) was depreciated since, version 1.5.
Axes.set_color_cycle(clist) 从 1.5 版开始折旧。
