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

Question

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

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起已弃用

Answer 2

.get_dtype_counts()是deprecated since 0.25.0，请改用.dtypes.value_counts()
