मल्टीइंडेक्स और टाइमज़ोन - जमे हुए सूची त्रुटि - पायथन, पांडा, बहु-सूचकांक

मैं एक multindex डेटाफ्रेमबैम के टाइमज़ोन को बदलने की कोशिश करता हूं मुझे एक जमे हुए सूची त्रुटि मिलती है। क्या किसी को कोई विचार है कि कैसे आगे बढ़ना है?

>>> array = [("s001", d) for d in pd.date_range(start="01/01/2014", end="01/01/2015", freq="H")] + [("s002", d) for d in pd.date_range(start="01/01/2014", end="01/01/2015", freq="H")]
>>> index = pd.MultiIndex.from_tuples(array, names=["sce", "DATES"])
>>> df = pd.DataFrame(np.random.randn(len(index)), index=index)

>>> df.index.levels[1] = df.index.levels[1].tz_localize("Etc/GMT-1", ambiguous = "NaT")

यह त्रुटि स्तर (लेकिन लेबल नहीं) सेट करते समय असंगतता से बचने के उद्देश्य से है, इसका उपयोग करें set_levels इस उद्देश्य के लिए कार्य करता है। (यह भी जगह में किया जा सकता है)

In [8]: df.index.set_levels(df.index.levels[1].
tz_localize("Etc/GMT-1", ambiguous = "NaT"),level=1)
