add new coordinates to an xarray. DataArray - Stack Overflow It appears that when adding a new coordinate, you need to pass also the dimension along which it's added So in this case, it would be: alternate_sample_weights=('samples', np zeros(5)))
assign_coords adds coordinates without a new dimension if the . . . - GitHub You are allowed to add new coordinates to a DataArray if they share existing dimensions You are not allowed to add coordinates with new dimensions, because it is enforced as an invariant of the DataArray data model that all coordinate dimensions are found on the DataArray variable as well
xarray. Dataset. assign_coords If a value is a standard data value — for example, a DataArray, scalar, or array — the data is simply assigned as a coordinate If a value is callable, it is called with this object as the only parameter, and the return value is used as new coordinate variables
xarray assign_coords does not work to set new coordinates I have a NetCDF file and trying to use xarray to read a variable (with no attributes and coordinates) then assign new attributes and coordinates to that Here is my python code:
xarray. DataArray. expand_dims Return a new object with an additional axis (or axes) inserted at the corresponding position in the array shape The new object is a view into the underlying array, not a copy If dim is already a scalar coordinate, it will be promoted to a 1D coordinate consisting of a single value
