在yolov5中加入plot_one_box函数实现画图功能时，出现TypeError: 'Colors' object does not support indexing错误怎么办？

Question

为了实现在视频流上显示内容，加入plot_one_box函数，但是运行时出现TypeError: 'Colors' object does not support indexing
错误，应该怎么解决呢？
在detect.py添加的plot_one_box

                    if save_img or view_img:  # Add bbox to image
                        label = '%s %.2f' % (names[int(cls)], conf)
                        plot_one_box(xyxy, im0, label=label, color=colors[int(cls)], line_thickness=3)

最后出现的错误结果：

Fusing layers... 
Model Summary: 213 layers, 7012822 parameters, 0 gradients
Traceback (most recent call last):

Answer 1

将其改为color=colors(0, True)
