minute专题
《python语言程序设计》2018版第7章第10题设计一个名为time的类,包括hour minute second
#main代码段 def main():a = int(time.time())total_second = int(a)current_second = total_second % 60total_minutes = total_second // 60current_minute = total_minutes % 60total_hours = total_minutes // 6
Deep Learning with PyTorch: A 60 Minute Blitz 要点整理
Tensor 创建 Construct a 5x3 matrix, uninitialized： x = torch.Tensor(5, 3) Construct a randomly initialized matrix x = torch.rand(5, 3) Operation 实现两个tensor的加法：x+y 1. x + y 2. torch.add(x, y)
Excel计算时间 活用 HOUR和MINUTE函数。计算出两个单元格的差，是几个小时
计算出两个单元格的差，是几个小时 =HOUR(E3-D3) + MINUTE(E3-D3)/60 计算时间，超过8小时，显示8小时，小于8小时，显示正常时间 =IF(IF(E3<>"",HOUR(E3-D3) + MINUTE(E3-D3)/60 -1,0)>8,8,IF(E3<>"",HOUR(E3-D3) + MINUTE(E3-D3)/60 -1,""))
解决“/tmp/crontab bad minute”问题
crontab在linux中用处很大，但是初次使用会出各种错误，其中一种错误就是 "/tmp/crontab.sdXvj4":5: bad minute errors in crontab file, can't install. Do you want to retry the same edit? ”，而通过该文章就可以解决 1 很简单，因为你的crontab格式
