| 672842007 | MDU6SXNzdWU2NzI4NDIwMDc= | 4307 | Cannot create Dataset from DataFrame containing CategoricalIndex with Intervals | 55156127 | open | 0 | 2 | 2020-08-04T14:35:02Z | 2022-04-17T18:08:10Z | CONTRIBUTOR | What happened:
Creating a Dataset from a DataFrame with a CategoricalIndex (where the categories are an IntervalIndex) raises the error:
What you expected to happen: I expected the output to be a Dataset object with the CategoricalIndex as one of the coordinates. Minimal Complete Verifiable Example: ```python import pandas as pd import xarray as xr df = pd.DataFrame({"name": list("abcdefghijk"), "age": range(11)}) df["age_group"] = pd.cut(df["age"], bins=5) df = df.set_index(["name", "age_group"]) df.to_xarray() # or xr.Dataset.from_dataframe(df) ``` Environment: Output of <tt>xr.show_versions()</tt>INSTALLED VERSIONS ------------------ commit: None python: 3.7.5 (default, Oct 25 2019, 10:52:18) [Clang 4.0.1 (tags/RELEASE_401/final)] python-bits: 64 OS: Darwin OS-release: 19.6.0 machine: x86_64 processor: i386 byteorder: little LC_ALL: None LANG: None LOCALE: None.UTF-8 libhdf5: 1.10.4 libnetcdf: 4.6.1 xarray: 0.15.1 pandas: 1.0.3 numpy: 1.18.1 scipy: 1.4.1 netCDF4: 1.4.2 pydap: None h5netcdf: None h5py: None Nio: None zarr: None cftime: 1.1.3 nc_time_axis: None PseudoNetCDF: None rasterio: 1.1.0 cfgrib: None iris: None bottleneck: None dask: None distributed: None matplotlib: 3.1.3 cartopy: None seaborn: 0.9.0 numbagg: None setuptools: 46.4.0.post20200518 pip: 20.0.2 conda: 4.8.3 pytest: None IPython: 7.13.0 sphinx: None |
