I know all the solutions on the internet say to give integer co-ordinates but that isn't working for me.

def box(x,y,w,h):
    print(x,y,w,h)
    print(type(x),type(y),type(w),type(h))
    cv2.rectangle(image, (int(x),int(y)) , (int(x+w),int(y+h)) , (255,0,0) , 2.0) ----> error

for i in indices.flatten():
    x,y,w,h = boxes[i][0],boxes[i][1],boxes[i][2],boxes[i][3]
    box(int(x),int(y),int(w),int(h))    

Output of debug

当我!pip install 'library_name' 在 kaggle 控制台中运行时，它会抛出此警告：

WARNING: Retrying (Retry(total=4, connect=None, read=None, redirect=None, status=None)) 
after connection broken by 'NewConnectionError('
<pip._vendor.urllib3.connection.HTTPSConnection object at 0x7fc7bd22aed0>:

')': /simple/pip/

最终不安装该库。

这个警告的原因是什么以及如何解决这个问题？
