问题描述*：标注工具Labelimg，正常运行显示，但是对图片点击Create RectBox画矩形框开始闪退，闪退出现以下代码
File “C:\ProgramData\anaconda3\Lib\site-packages\libs\canvas.py”, line 530, in paintEvent
p.drawLine(self.prev_point.x(), 0, self.prev_point.x(), self.pixmap.height())
TypeError: arguments did not match any overloaded call:
drawLine(self, l: QLineF): argument 1 has unexpected type ‘float’
drawLine(self, line: QLine): argument 1 has unexpected type ‘float’
drawLine(self, x1: int, y1: int, x2: int, y2: int): argument 1 has unexpected type ‘float’
drawLine(self, p1: QPoint, p2: QPoint): argument 1 has unexpected type ‘float’
drawLine(self, p1: Union[QPointF, QPoint], p2: Union[QPointF, QPoint]): argument 1 has unexpected type ‘float’
而且点击Create RectBox点没有线出来，过几秒闪退

解决问题：
因为可能你安装的Anaconda里python版本过高，比如装的Anaconda是python3.11版本，重把python版本改低一点，那就重新装一个，用anaconda prompt。文章来源：https://www.toymoban.com/news/detail-588859.html
我们可以新建python低版本环境，在里面在安装。参考以下链接。
