这个错误提示表明你在导入`StandardScaler`时拼写错误,应该是`StandardScaler`而不是`StandardScalerv`。
你可以尝试将导入语句修改为以下形式:
```python
from sklearn.preprocessing import StandardScaler
```
如果修改后仍然出现错误,那么可能是`scikit-learn`库没有正确安装。你可以尝试使用以下命令来安装`scikit-learn`:
```python
pip install -U scikit-learn
```
如果你使用的是Anaconda发行版,则可以使用以下命令来安装:
```python
conda install scikit-learn
```
安装完成后,再次尝试导入`StandardScaler`类即可。

import numpy as np import pandas import pandas as pd import matplotlib from sklearn import naive_bayes from sklearn.preprocessing import MinMaxScaler from sklearn.preprocessing import StandardScaler from sklearn.preprocessing import normalize from sklearn.preprocessing import Binarizer from sklearn.impute import SimpleImputer from sklearn.preprocessing import OneHotEncoder import matplotlib.pyplot as plt from sklearn.metrics import roc_curve, auc from sklearn.model_selection import train_test_split from sklearn.linear_model import LogisticRegression from sklearn.metrics import confusion_matrix matplotlib.rc("font", family='Microsoft YaHei') data=pd.read_csv(r'D:\杂货铺\机器学习\银行数据集.csv',header=None)
这段代码导入了一系列的Python库,包括NumPy、Pandas、Matplotlib、scikit-learn等。其中,NumPy是Python科学计算的核心库,Pandas是数据处理的重要库,Matplotlib是绘图库,scikit-learn是机器学习库。接下来,使用Pandas读取一个CSV文件,该文件路径为D:\杂货铺\机器学习\银行数据集.csv,文件没有列名,所以header参数设置为None。
