xarray
A Python library for working with labeled multi-dimensional arrays.
- Reshape uneven xarray time series into fixed windows without per-group loops
Reshape an irregularly sampled xarray time series into fixed (window, position_in_window) blocks using vectorized window labels (dt.floor), within-window positions from groupby(...).cumcount(), and set_index + unstack — no per-group slicing
- Diagnose and fix xarray coordinate alignment (join) surprises
Diagnose xarray alignment surprises from the symptom — shrunken results (default inner join), all-NaN (non-overlapping labels), ValueError on unlabeled dims, silently dropped conflicting coordinates, no alignment for in-place ops — then tak
