【笔记】tqdm 进度条：desc（‘str‘）: 传入进度条的前缀，mininterval（float）：最小的更新时间 [default: 0.1] sec，set

附：【笔记】python 中 *args 和 **kwargs 的用法：*args 无关键字参数，接收元组、列表；**kwargs 有关键字参数，接收字典_nyist_yangguang的博客-CSDN博客

注： f"{}" 的说明：

eg1：

from tqdm import tqdm
import time
epoch_size=100
Epoch=1000
epoch=45

with tqdm(total=epoch_size, desc=f'Epoch {epoch + 1}/{Epoch}', postfix=dict, mininterval=0.01) as pbar:
    for i in range(10):
        time.sleep(0.5)
        tqdm(total=epoch_size, desc=f'Epoch {epoch + 1}/{Epoch}', postfix=dict,mininterval=1)
        pbar.update(1)

#trange 是tqdm（range）的简用方式：
for i in trange(int(1e8)):
    pass
