import pandas as pd

import numpy  as np

df = pd.DataFrame({'ID':[1,2,3],'Name':['Tim','Victk','Nick']})

#重新设置索引

df = df.set_index('ID')

df.to_excel('F:/RF/output.xlsx')

print('OK ')

 

 

 

第一次使用遇到报错：

ImportError: Unable to import required dependencies:numpy:

Please note and check the following:

* The Python version is: Python3.7 from "F:PYpython.exe" * The NumPy version is: "1.22.3"

and make sure that they are the versions you expect.Please carefully study the documentation linked above for further help.

Original error was: No module named 'numpy.core._multiarray_umath'

实际上有安装numpy，只不过版本不匹配。重新卸载numpy后安装

pip uninstall unmpy

pip install numpy
