TypeError: setValue(self, a0: int): argument 1 has unexpected type 'float'

windows电脑训练

python yolo_runner2.py --mode train --model "E:/cn/yolo/weights/yolov12x.pt" --data "E:/cn/yolo/datasets/260120_5/data.yaml" --epochs 30 --imgsz 1280 --batch 2 --workers 8 --rect --cache --cos_lr --device cpu --lr0 0.0012 --optimizer SGD --close_mosaic 50 --patience 100 --project "E:/cn/yolo/output" --name 260120_5train

直接修改文件的方法

根据错误信息，文件在：
D:\conda\envs\labelimg\lib\site-packages\libs\canvas.py

使用任意文本编辑器打开文件，比如：

notepad "D:\conda\envs\labelimg\lib\site-packages\libs\canvas.py"

步骤2：找到并修改第530行

在文件中搜索 drawLine(self.prev_point.x()，找到类似这样的代码块：

通常在 paintEvent 方法中

def paintEvent(self, event):

... 前面的代码 ...

if self.prev_point and not self.out_of_pixmap(self.prev_point):

p.setPen(QPen(QColor(0, 0, 0), 1, Qt.DotLine))

p.drawLine(self.prev_point.x(), 0, self.prev_point.x(), self.pixmap.height()) # 第530行

p.drawLine(0, self.prev_point.y(), self.pixmap.width(), self.prev_point.y()) # 第531行

... 后面的代码 ...

步骤3：进行修改

修改前：

p.drawLine(self.prev_point.x(), 0, self.prev_point.x(), self.pixmap.height())
p.drawLine(0, self.prev_point.y(), self.pixmap.width(), self.prev_point.y())

修改后：

p.drawLine(int(self.prev_point.x()), 0, int(self.prev_point.x()), int(self.pixmap.height()))
p.drawLine(0, int(self.prev_point.y()), int(self.pixmap.width()), int(self.prev_point.y()))
