Thanks for the report.
Could you add a bit more context about what you are trying to achieve with attr? attr doesn't really work in pandas either and support is spotty at most.
from dask.
I also experienced a problem with pandas
and .attrs
: copied DataFrame
objects where not containing a copy of .attrs
. (I initially thought it was a geopandas
problem geopandas/geopandas#2920), but then it turned out to be from pandas
pandas-dev/pandas#54134. Fortunately the bug above is now fixed. Which other problems did you find?
The use case for .attrs
we have in the library we developed https://github.com/scverse/spatialdata/, is to store metadata associated to GeoDataFrame
and DataFrame
objects (both lazy and non-lazy). The metadata mostly contain json-like information that describes how various spatial objects are aligned together.
