Bug report
Bug summary
Creating AxesGrid using cartopy GeoAxes as axis_class raises TypeError: 'method' object is not subscriptable. Seems to be due to different behaviour of axis attr. for mpl_toolkits.axes_grid1.mpl_axes.Axes and other axes instances (like GeoAxes) where axis is only a callable. The error is raised in method mpl_toolkits.axes_grid1.axes_grid._tick_only when trying to access keys from axis attr.
Code for reproduction
<!--A minimum code snippet required to reproduce the bug.
Please make sure to minimize the number of dependencies required, and provide
any necessary plotted data.
Avoid using threads, as Matplotlib is (explicitly) not thread-safe.-->
import matplotlib.pyplot as plt
from cartopy.crs import PlateCarree
from cartopy.mpl.geoaxes import GeoAxes
from mpl_toolkits.axes_grid1 import AxesGrid
fig = plt.figure()
axes_class = (GeoAxes, dict(map_projection=PlateCarree()))
gr = AxesGrid(fig, 111, nrows_ncols=(1,1),
axes_class=axes_class)Actual outcome
<!--The output produced by the above code, which may be a screenshot, console output, etc.-->
