'Axes' object has no attribute 'get_geometry'

[liuchao95]

Hello developers,
I installed the ipart=3.6.1 using conda under python=3.10,
When I test the functionality of this package using "compute_ivt.py" under the "scripts" directory. The calculation procedure is fine, but it shows the following plotting error:
AttributeError: 'Axes' object has no attribute 'get_geometry'.
The corresponding package version is also attached, cartopy=0.21.1, matplotlib=3.7.2.
I think it may be related to the update of the relevant packages that abort the old use of the "get_geometry" method. Please check it.

Hi @liuchao95

Thanks for reporting this bug. I believe this is because of some API changes in newer versions of matplotlib. I will try to patch it up in a few days.

Before that, you could either delete all the plotting code (starting from Line 51 in compute_ivt.py) and only let the script output the netcdf results, or, downgrade the matplotlib to a lower version, for instance, try conda install matplotlib=3.2.

Hope that helps.

Thanks for your concern and notes. It's fine for me to just focus on the calculation part at this stage.

Hi,

I solved the issue by looking at a bit the older version of matplotlib.

In the getGeo function of the Plot2D class (ipart/utils/plot.py) I modified these two lines as

geo=self.ax.get_subplotspec().get_geometry()[:2]
subidx=self.ax.get_subplotspec().get_geometry()[-1]+1

The Python notebooks are now working. I must admit that I made it works and I didn't further test it. So maybe this is just a workaround rather than a solution.
