copy.deepcopy doesn't work for classes defined in cartopy.crs.
It returns a copy with all parameters set to their default values. As a result these
projections are not usable with pickle or multiprocessing.
import cartopy.crs as ccrs
from copy import deepcopy
def test_proj(Projection, args=1):
orig = Projection(args)
copy = deepcopy(a)
# copy should be the same as orig
return {
(key, (orig.proj4_params[key], copy.proj4_params[key]))
for key in orig.proj4_params
if orig.proj4_params[key] != copy.proj4_params[key]
}
print(test_proj(ccrs.RotatedPole))
print(test_proj(ccrs.PlateCarree))
There is no traceback, code just silently does the wrong projections.
