如何对pandas DataFrame进行切片，使pylance不会给出返回类型为NDFrame的错误？

import pandas as pd

data = {'A': [1, 2, 3, 4, 5],
        'B': [6, 7, 8, 9, 10],
        'C': [11, 12, 13, 14, 15]}
df = pd.DataFrame(data)

sliced_df = df.loc[:, ['A', 'B']]

sliced_df = sliced_df.astype({'A': int, 'B': int})

import pandas as pd

data = {'A': [1, 2, 3, 4, 5],
        'B': [6, 7, 8, 9, 10],
        'C': [11, 12, 13, 14, 15]}
df = pd.DataFrame(data)

sliced_df = df.loc[:, ['A', 'B']]
sliced_df = sliced_df.astype({'A': int, 'B': int})
