A simple fix would be to replace line 6 in basemap/proj.py

from matplotlib.cbook import dedent

except ImportError:

    from matplotlib.cbook import dedent

as already implemented in basemap/init.py

I can probably prepare a merge request. Would this be useful for such a simple change?

[WeatherGod]

Sure, feel free to do so, and I'll merge it. Do keep in mind that this package isn't really maintained anymore. Please try Cartopy instead.

We also try to work with cartopy, but cartopy still has a lot of serious issues, which are not as easily addressed as this for our usecase (e.g. with stereographic projections).

[joernu76]

The tests seem to fail due to failure to install libgeos with the desired version, not related with my changes IMO.

OK, the travis stuff is quite outdated. I try to fix it separately, but with the current state of matplotlib, it will be likely impossible to get it to pass without accepting both changes.

I need the working basemap in anaconda. Could you do a new release, please? 1.2.2rel?
Update: Okay, I see that basemap is already decoupled from releases here. Forget about my request. Thanks, again!

@joernu76 : how did you get the fix in anaconda?
I conda-installed the latest basemap=1.3 but the fix is not implemented.

Personally, I downgraded matplotlib to 2.2.4 to get it working.

[joernu76]

@Kerybas The fix is not implemented in anaconda, yet. There are some problems with respect to release numbers due to the deprecation of basemap.
Downloading and manually installing basemap from here might help, currently, or to manually patch your anaconda-basemap with the latest diff (what I did until the patch goes into anaconda; I hope this will happen within the next few weeks...).

@joernu76 @Kerybas

I'm facing the same problem here. Any luck so far?

[joernu76]

The bug was fixed in this repository and it has also been fixed since 19th Aug in the anaconda distribution. See here
conda-forge/basemap-feedstock#64
So either using a fresh anaconda installation or a clone of this repository should work unless you discovered a new bug.
