可以将文章内容翻译成中文,广告屏蔽插件可能会导致该功能失效(如失效，请关闭广告屏蔽插件后再试): 问题: In config file, we are given the default Augmentation option as shown below. data_augmentation_options { random_horizontal_flip { } } But I wondered how it works with the bounding box(ground truth box) values given with the training images. so I looked at preprocessor.py , random_horizontal_flip() takes 'boxes=None' parameter. Since no argument is given in the config file, I assume this flip does not account bounding box when it does the random horizontal flip. My question is what arguments do I use to add the value of bounding box in the

可以将文章内容翻译成中文,广告屏蔽插件可能会导致该功能失效(如失效，请关闭广告屏蔽插件后再试): 问题: This question is a slight modification of the bounding box example. I'm trying to understand how to draw simple shapes. I just want to replace the bounding box with a diagonal line from the upperLeft point to the lowerRight point. However, QLine() does not appear to have a show() method and viewport() has no addItem() method. So, I think the line is not being displayed. Here is my modification of the showBoxes method: def showLines(self): while self.boxes: self.boxes.pop() #self.boxes.pop().deleteLater() #Qline has no deleteLater(). Does

gnome-boxes 的安装与使用 1. 安装 gnome 软件中心里就能找到，直接安装即可。或者直接 apt install gnome-boxes 但坑跌的是，选择安装盘后会提示“boxes 设置错误”，再无其它详细信息，让人摸不着头脑，说好的开箱即用呢? 经查看 syslog 中的运行出错信息，发现是有些依赖没装：qemu-system-x86 qemu-utils，装完后正常使用 2. 使用 boxes 配置项很少，目前也就能设置个内存和硬盘大小，而且虚拟机文件默认保存在 ~/.local/share/gnome-boxes 里，因为家目录空间比较小，所以需要调整下文件路径 查看 virsh -c qemu:///session pool-list virsh -c qemu:///session pool-info gnome-boxes virsh -c qemu:///session pool-dumpxml gnome-boxes 编辑 virsh -c qemu:///session pool-edit gnome-boxes 重载 virsh -c qemu:///session pool-destroy gnome-boxes virsh -c qemu:///session pool-start gnome-boxes 3. 安装虚拟机工具

原题链接在这里： https://leetcode.com/problems/remove-boxes/ 题目： Given several boxes with different colors represented by different positive numbers. You may experience several rounds to remove boxes until there is no box left. Each time you can choose some continuous boxes with the same color (composed of k boxes, k >= 1), remove them and get k*k points. Find the maximum points you can get. Example 1: Input: [1, 3, 2, 2, 2, 3, 4, 3, 1] Output: 23 Explanation: [1, 3, 2, 2, 2, 3, 4, 3, 1] ----> [1, 3, 3, 4, 3, 1] (3*3=9 points) ----> [1, 3, 3, 3, 1] (1*1=1 points) ----> [1, 1] (3*3=9 points) ----> []

FC（Formatting Context） 它是W3C CSS2.1规范中的一个概念，定义的是页面中的一块渲染区域，并且有一套渲染规则，它 决定了其子元素将如何定位 ，以及 和其他元素的关系和相互作用 。 BFC（block formatting context） 直译为“块级格式化上下文” W3C原文： Floats, absolutely positioned elements, block containers (such as inline-blocks, table-cells, and table-captions) that are not block boxes, and block boxes with 'overflow' other than 'visible' (except when that value has been propagated to the viewport) establish new block formatting contexts for their contents. In a block formatting context, boxes are laid out one after the other, vertically, beginning at the top of a containing block. The

Little Vasya had n boxes with balls in the room. The boxes stood in a row and were numbered with numbers from 1 to n from left to right. Once Vasya chose one of the boxes, let's assume that its number is i , took all balls out from it (it is guaranteed that this box originally had at least one ball), and began putting balls (one at a time) to the boxes with numbers i  + 1, i  + 2, i  + 3 and so on. If Vasya puts a ball into the box number n , then the next ball goes to box 1, the next one goes to box 2 and so on. He did it until he had no balls left in his hands. It is possible that Vasya puts
