一个小例子 # 1. An Embedding module containing 7 tensors of size 3 embedding = nn.Embedding(7, 3) # A batch of 2 samples of 4 indices each input = torch.LongTensor([[1, 2, 4, 5], [4, 3, 2, 6]]) # 2 x 4 print(embedding(input).size(
You are given a 0-indexed binary string s which represents a sequence of train cars. s[i] = '0' denotes that the ith car does not contain illegal goods and s[i] = '1' denotes that the ith car does contain illegal goods. As the train co
描述 Given S, a set of integers, find the largest d such that a + b + c = d where a, b, c, and d are distinct elements of S. 输入 Several S, each consisting of a line containing an integer 1 <= n <= 1000 indicating the number of elements in S, followed

设置命令行flag 一般使用flag的原因是为了能在命令行指定一个非默认值。以 foo.cc 为例，可能的用法是： app_containing_foo --nobig_menu -languages="chinese,japanese,korean" ... 执行 ParseCommandLineFlags 会设置 FLAGS_big_menu = false ， FLAGS_languages = "chinese,j
当使用avfilter_graph_parse_ptr接口，传入filters的参数为fps=fps=15;scale=w=960:h=540 ffmpeg就会输出错误：Invalid filterchain containing an unlabelled output pad: "fps=fps=15;scale=w=960:h=540" 说明多filter不能成功连接。 需要对各个filter的输入和输出指定. 因为默认
一个元素的尺寸和位置经常受其包含块(containing block)的影响。大多数情况下，包含块就是这个元素最近的祖先块元素的内容区，但也不是总是这样。在本文中，我们来过一遍确定包含块的所有因素。 当一个客户端代理（比如说浏览器）展示一个文档的时候，对于每一个元素，它都产生了一个盒子。每一

说到position，稍微对css了解的能马上说出四个属性值：static 、relative、absolute、fixed。 更深一步去讨论，牵扯出诸如上文提到的normal flow、containing block、bfc、margin collapse，base line，有多少人能很好的回答完整呢，所以在此做一个自己的总结归纳。 1.normal flow norma

实现子元素在父元素中的绝对定位必须满足以下两个条件： 1、父元素要有相对定位属性（position：relative）， 2、子元素设置绝对定位（position：absolute），并且同时加四个方向（top，bottom，left，right）的任意方向的属性值 子元素的绝对定位是包含块“containing block”的知识， 在 10.1 节 (http:
