2 years ago Hi @lippinpauly, This was something that broke (again) semi-recently and I believe it was from either a release of Cartopy that came out after we had released the fix in the last wrf-python version, or that my cartopy was not up to date when testing the wrf-python release so it wasn't caught then. If you are able to, downgrade your Cartopy to 0.20.0 and that should fix it for the time being. if you are currently on Cartopy 0.20.0 and wrf-python 1.3.3, definitely let me know as this error shouldn't happen with those two versions based on what I have found.
Overall, this is on our radar and hopefully there will be a fix soon!

Hi all, I am new to wrf-python and I am trying to do the 2021 tutorial. During the plotting of slp (sea level Pressure) variable using wrf_python, I get this error 'MercatorWithLatTS' object has no attribute '_x_limits' over the line (code) cart_proj = get_cartopy(slp)
Any help would be really appreciated
I could see that this issue is discussed and closed recently in #162. However, the solution described in that issue is to update the wrf-python to v1.3.3 and use cartopy >0.20. I am using the recent versions and I still have the same issue.
