属性错误：'DataFrame'对象没有属性'get_dtype_counts'。

Question

我想使用 get_dtype_counts() 方法来查看DataFrame数据类型的计数，但是出现了错误。请帮忙解决。

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()

Answer 1

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起已被弃用。

Answer 2

.get_dtype_counts()已经自0.25.0版本开始被弃用，请使用.dtypes.value_counts()替代
