.npz文件的保存

import numpy as np
import os

#要保存文件的文件夹
folder_path=r'C:\Users\Raytrack\Desktop\练习'
my_train_loss=[1,2,3,4]
my_eval_loss=[6,7,8,9]
#文件的名字为loss.npz
np.savez(os.path.join(folder_path, 'loss.npz'), my_train_loss=my_train_loss, my_eval_loss=my_eval_loss )

.npz文件的加载

import numpy as np
import os
# 读取npz文件
folder_path =r'C:\Users\Raytrack\Desktop\练习'
data = np.load(os.path.join(folder_path, 'loss.npz'))

# 获取my_train_loss的值
my_train_loss = data['my_train_loss']
my_eval_loss = data['my_eval_loss']
print("my_train_loss:", my_train_loss)
print("my_eval_loss :",my_eval_loss )

输出结果为

如果不关闭运行程序，这个npz文件一直显示在运行，修改不了名字，除非把IDE关掉。当然加上一代码就OK了

# 关闭npz文件
data.close()
