Time stamp error

[sebourban]

Hello,

I tried loading a geometry file using

import xarray as xr
ds = xr.open_dataset("geo.slf", engine="selafin")

and I get the following error message:

Traceback (most recent call last):
  File "/home/sebourban/opentelemac/test.py", line 2, in <module>
    ds = xr.open_dataset("geom_world06_stb.slf", engine="selafin")

    times = [datetime(*slf.header.date) + timedelta(seconds=t) for t in slf.time]
             ^^^^^^^^^^^^^^^^^^^^^^^^^^
TypeError: datetime.datetime() argument after * must be an iterable, not NoneType

When I try on a time varying file I get :
Format "" is unknown and is forced to "SERAFIN "
but maybe this is OK - just a little odd to confirm that I have a SERAFIN when I know I do ..

You probably know the answer already ? thanks for looking into it.
Sébastien.

@sebourban
try to pip install xarray-selafin again and let us know if your problem was solved with the latest fix
check maybe if you have the right version: it should be 0.1.4

so to be sure:
pip install xarray-selafin==0.1.4
