Question

我在努力利用自动数据集扩大数据。

import matplotlib.pyplot as plt
import pandas as pd
import numpy as np
import seaborn as sns
%matplotlib inline

data = pd.read_csv( data.csv , nrows=50000)
data.head()

from sklearn.preprocessing import StandardScaler

scaler = StandardScaler()
scaler.fit(data)

scaled_data = scaler.transform(data)

scaled_data.head()

一如操作守则,总是有同样的错误。

---------------------------------------------------------------------------
AttributeError                            Traceback (most recent call last)
~AppDataLocalTemp/ipykernel_13244/2182372482.py in <module>
----> 1 scaled_data.head()

AttributeError:  numpy.ndarray  object has no attribute  head

Anyone know how I can fix this?

Answer 1

这是因为NumPy阵列没有head()方法。之后,你可以尝试将其转换成Pandas数据框架,例如:

scaled_data_df = pd.DataFrame(scaled_data, columns="number-of-columns")

scaled_data_df.head()
