prep_data occur TypeError: unhashable type: 'list'

[xigrug]

I use xarray to read netcdf data

import xarray as xr from windspharm.xarray import VectorWind from windspharm.tools import prep_data, recover_data, order_latdim from windspharm.examples import example_data_path nc = xr.open_dataset('era5/era5_3d_201906070809.nc') uwnd = nc.u uwnd, uwnd_info = prep_data(uwnd, 'tzyx')

<xarray.DataArray 'u' (time: 4, level: 22, latitude: 721, longitude: 1440)> [91365120 values with dtype=float32] Coordinates:

• longitude (longitude) float32 0.0 0.25 0.5 0.75 ... 359.25 359.5 359.75
• latitude (latitude) float32 90.0 89.75 89.5 89.25 ... -89.5 -89.75 -90.0
• level (level) int32 1 2 3 5 7 10 20 30 ... 400 500 600 700 850 925 1000

the error message are as following:

how to fix this? Thanks
