Still a desired [FEA]
Ideally, this would also be enabled by an implementation on dask.dataframe, so we can enable group quantile/percentile on CPUs and GPUs
It looks like median is now implemented
In [27]: ddf.groupby(['id4', 'id5'])[['v3']].median().compute()
Out[27]:
v3
id4 id5
0 5 1.0
1 4 2.0
2 3 1.0
3 2 2.0
4 1 1.0
5 0 2.0
quantile remains unimplemented.
Is your feature request related to a problem? Please describe. I'd like to calculate median and/or quantile on a column after groupbying a dask-cudf data frame.
EDIT 5/10/2024: median is now implemented
Describe the solution you'd like I want the following code to work and generate correct results:
Additional context I am using Rapids 0.13 nightly release in conda env, with dask 2.12.0 version.
