我正在嘗試按列「DayOfYear」進行數字排序，但它不允許我將它轉換爲帶有熊貓的數據框，但是我沒有使用數字排序的運氣按列Python的數字排序
results7 = ([['1', '660.206159375', '2200.969', '1588.2815', '831.8674',
'521.3459', '329.77015', '205.89374', '102.9523'],
['10', '932.475360938', '2381.846', '2098.8083', '1289.0055',
'780.2308', '522.78565', '340.15073', '298.4486'],
['11', '914.067898437', '2698.957', '1922.7277', '1259.1625',
'731.6858', '505.171', '267.1976', '203.4595'],
['12', '786.08815', '2580.748', '1823.5057', '908.63865',

'734.7388', '512.9898', '241.98641', '167.2151'],
['', nan, nan, nan, nan, nan, nan, nan, nan]], dtype=object
])
names50 = ['DayOfYear','AvgFlow','Max','n95th','n75th','n50th','n25th','n5th','Min']
results9 = pd.DataFrame(results8,columns=names50)
results10 = results9.astype(str).convert_objects(convert_numeric=True)
results11 = results10[~np.isnan(results10).any(axis = 1)]
results12 = np.sort(results11, order = 'DayOfYear')
我收到的
ValueError: Cannot specify order when the array has no fields.
錯誤消息當我把它轉換成一個pd.DataFrame難道我不指定領域還當我嘗試做我收到一條錯誤消息.dtype：
AttributeError: 'DataFrame' object has no attribute 'dtype'
我在這裏做錯了什麼？
這真的results7在上面定義的？如果是這樣，你能提供一個定義result8（傳遞給DataFrame構造函數的定義）嗎？ – Alex 2015-03-02 16:34:43
您當前的帖子代碼不會重現您的錯誤，或者至少我無法運行它，您是否可以發佈最小代碼來重現您的錯誤 – EdChum 2015-03-02 16:34:52
DataFrames沒有'dtype'，DataFrame列。 – Alexander 2015-03-02 16:35:06
