xarray.Dataset.convert_calendar()

[Ranjan Kumar Sahu]

I was trying to convert the calendar type of a dataset to a standard calendar. The function xarray.Dataset.convert_calendar() doesn't seem to work.

ds = xr.open_dataset('/home/scilab/Desktop/test.nc')
ds = ds.convert_calendar('standard',use_cftime=True)
print(ds)

Traceback (most recent call last):
  File "/home/scilab/Desktop/rotary_spectra/test_calendar.py", line 17, in <module>
    ds = ds.convert_calendar('standard',use_cftime=True)

File "/home/scilab/PycharmProjects/test2/venv/lib/python3.8/site-packages/xarray/core/common.py", line 246, in __getattr__
    raise AttributeError(
AttributeError: 'Dataset' object has no attribute 'convert_calendar'

Am I missing something?

any help is appreciated.

Hi Ranjan,

Which version of xarray are you using?  Dataset.convert_calendar was added in version 0.20.0 (November of 2021).  The error message seems to indicate that in your version it had not been defined yet.

Best,

Spencer
