TypeError: only integer scalar arrays can be converted to a scalar index

报错only integer scalar arrays can be converted to a scalar index

        color = colors[class_id]

修改为 

        color = np.array(colors)[class_id]

参考成功解决TypeError: only integer scalar arrays can be converted to a scalar index - 简书 

报错Scalar value for argument 'color' is not numeric

颜色值不对

报错代码

cv2.rectangle(frame, (x, y), (x + w, y + h), color, 3)

修改：在使用前转换一下，添加一句

color = tuple([int(x) for x in color])  # 设置为整数
