DEPR offsets: rename 'M' to 'ME' by natmokval · Pull Request #52064 · pandas-dev/pandas (original) (raw)

In [1]: In [10]: df = pd.DataFrame({'ts': pd.period_range('2000', periods=3), 'val': [1,2,3]}) ...: ...: In [11]: df.set_index('ts').resample('MS').mean()

AttributeError Traceback (most recent call last) File period.pyx:2854, in pandas._libs.tslibs.period.freq_to_dtype_code()

AttributeError: 'pandas._libs.tslibs.offsets.MonthBegin' object has no attribute '_period_dtype_code'

The above exception was the direct cause of the following exception:
