How can numpy read data from an Excel file?

You can use the pandas library to read Excel data and convert it into a numpy array. Here is an example code:

import pandas as pd
import numpy as np

# 读取Excel文件
df = pd.read_excel('data.xlsx')

# 将数据转换为numpy数组
data = df.to_numpy()

Please note that you need to install the pandas library to run the above code. You can install pandas using the following command:

pip install pandas

The read_excel method in the code is used to read Excel files and store them in a DataFrame object. Then, the to_numpy method is used to convert the DataFrame object into a numpy array. Finally, you can use the data array for further data processing and analysis.
