Bug in summary.pandas_frame

[eivindjahren]

Put the following code in a test.py:

from resdata.summary import Summary

smry = Summary("test-data/local/ECLIPSE/cp_simple3/SHORT.UNSMRY")
smry.pandas_frame(time_index=smry.time_range(interval="1Y"), column_keys=["WELL:NAME"])

With pandas 2.0 you get the following exception:

Traceback (most recent call last):
  File "<string>", line 17, in __PYTHON_EL_eval
  File "test.py", line 9, in <module>
    df = smry.pandas_frame(time_index=yearly_dates, column_keys=["GGPT:NNA"])
