定义进度条函数

import time

def process_bar(percent, start_str='', end_str='', total_length=20):
    bar = ''.join(['='] * int(percent * total_length)) + '>'
    bar = '\r' + start_str + '{:0>4.1f}% ['.format(percent*100) + bar.ljust(total_length) + ']' + end_str
    print(bar, end='', flush=True)

调用

for i in range(100):
    time.sleep(0.1)
    # t代表train, v代表validate
    end_str = ' - used: %s - loss: t%.4f/\033[0;34mv%.4f\033[0m (best: t%.4f/\033[0;34mv%.4f\033[0m) - acc: t%.0f%% (best: t%.0f%%)' % ('01:20:34', 0.12, 0.11, 0.08, 0.03, 98, 97)
    process_bar(i/100, start_str='', end_str=end_str, total_length=20)

运行效果

99.0% [===================>] - used: 01:20:34 - loss: t0.1200/v0.1100 (best: t0.0800/v0.0300) - acc: t98% (best: t97%)
