进行这个重构是因为Python的动态类型难于拿捏,在过去三年pyETRC的开发过程中,由于数据结构设计的草率等原因,代码难以维护。另外,使用Python开发时,对对象生命周期的控制较弱(由于赋值语义问题,多个对象共享同一个数据对象时容易出问题),对数据结构的控制不够精细(并不是说不能,但用Python写链表之类的东西总是怪怪的)...

I see theGithub Page for Python Mac App Store. It looks like you have solved all of the technical challenges, congratulations! I notice you have not specified a license file, which I believe is an obstacle to deploying Qt without buying a $1000+ Qt Commercial license. In fact if you go...

The documentation of certain container class functions refer to default-constructed values; for example, QVector automatically initializes its items with default-constructed values, and QMap::value() returns a default-constructed value if the specified key isn't in the map. For most value types, ...
qt creator创建cmake构建的程序,无法启动调试(点左下角运行不出结果 No executable specified.) 如图: 参考解决办法:Qtcreator 调试cmake 好像没什么用 找到这个地方,将运行配置改成自己要运行的那个 点击构建,点击调试,就能正常调试了 而且点左下角运行也能直接出结果了,不会显示No executable specified. 分割线—...
Labelme 支持对图像进行多边形、矩形、圆、折线,点形式的标注,可用于目标检测,语义分割,图像分类等任务。作为一款开源工具,labelme 布局简单、但安装部署繁琐、数据管理困难,仅支持 JSON格式输出。支持对象检测、图像语义分割数据标注,实现语言为Python与QT。支持
