tqdm pbar.set_postfix使用

参考代码来自https://blog.csdn.net/qq_32464407/article/details/81113373

# -*- coding: utf-8 -*-
 
from tqdm import tqdm
from collections import OrderedDict
 
total = 10000 #总迭代次数
loss = total
with tqdm(total=total, desc="进度条") as pbar:
    for i  in range(total):
        loss -= 1 
#        pbar.set_postfix(OrderedDict(loss='{0:1.5f}'.format(loss)))
        pbar.set_postfix({'loss' : '{0:1.5f}'.format(loss)}) #输入一个字典，显示实验指标
        pbar.update(1)
 

在命令行的输出为，会显示进度情况

进度条: 100%|███████| 10000/10000 [00:00<00:00, 16709.54it/s, loss=-20000.00000]
