AttributeError: 'PandasIndex' object has no attribute 'dtype' #6880
Description
What is your issue?
Hi, all
I tried to load the xarray.Dataset that was saved a couple of months ago by using dill as follows:
with open(rslt_path + snio_fname, "rb") as inputf:
ppsp_snios = dill.load(inputf)
The problem is that I got an attribute error AttributeError: 'PandasIndex' object has no attribute 'dtype' after I updated the xarray version 2022.6.0. when I did ppsp_snios.keys() and cannot use for further calculation. However, I can access this after I downgraded to version 0.19.0. Can anyone have any suggestions to solve this problem?
