AttributeError：“DataFrame”对象没有属性“get_dtype_counts”

Question

我想使用方法查看 DataFrame 中数据类型的计数，get_dtype_counts()但它给出了错误。请帮忙。

import pandas as pd
import numpy as np

df = pd.DataFrame(np.arange(5))
df

输出

    0
0   0
1   1
2   2
3   3
4   4

错误

df.get_dtype_counts()

In [20]: import pandas as pd
    ...: import numpy as np
    ...:
    ...: df = pd.DataFrame(np.arange(5))

In [21]:

In [21]: df.dtypes.value_counts()
Out[21]:
int64    1
dtype: int64

.get_dtype_counts()自版本 0.25.0 起已弃用
