求助，cv2.error: OpenCV(4.9.0) :-1: error: (-5:Bad argument) in function ‘line‘

我的代码

with open("video.txt",'r',encoding='utf-8') as file:
 
    #video1=[]
    number1=[]
    number2 = []
    number3 = []
    number4 = []

            #print(type(j))
            #print(type('[\s]'))

    for k in range(0, len(number1)-1):
        if number2[k] > m:
            number4[number1[k]-1] = m
    # number3是每帧的人数，number4是累计人数

我的报错

翻了一些文章说是mat不连续，要用np.ascontiguousarray（）函数，但是我作为小白研究不明白，在文中注释的地方插入，还是相同的报错。
