Question

我有以下代码给我错误。我试图更改if条件，但问题似乎出在其他地方。我将不胜感激。

if humanRegion_bbs and belongings_bbs :
            x_left = max(humanRegion_bbs[0],belongings_bbs[0])
            y_top = max(humanRegion_bbs[1],belongings_bbs[1])
            x_right = min(humanRegion_bbs[2],belongings_bbs[2])
            y_bottom = min(humanRegion_bbs[3],belongings_bbs[3])

回溯：

Traceback (most recent call last):
  File "/home/prashant/anaconda3/envs/vaak_p36/lib/python3.6/multiprocessing/process.py", line 258, in _bootstrap
    self.run()

    oneObject.setBelongings(image,humanRegion_bbs,belongings_bbs)

    x_left = max(humanRegion_bbs[0],belongings_bbs[0])
ValueError: The truth value of an array with more than one element is ambiguous. Use a.any() or a.all()

我希望humanRegion_bbs和所有物_bbs都是一些数字。是因为其他一些代码行吗？

如果您希望列表中至少包含一个非零元素，则应使用any()：

if any(humanRegion_bbs) and any(belongings_bbs):

如何解决ValueError？
