import picklepickle.dump(data,open('file_path','wb')) #后缀.pkl可加可不加

pickle.dump(data,open('file_path', 'wb'),protocol=4)

data= pickle.load(open('file_path','rb'))

import numpy as npnp.savez('file_path/file_name.npz', data1=X,data2=y)

with np.load('file_path/file_name.npz') as data:X = data['data1']y= data['data2']

dataframe_file.to_csv("file_path/file_name.csv", index=False)

import pandas as pddf = pd.read_csv('file_path/file_name.csv')
