error in iou__batches

[day-night-py]

yy1 = np.maximum(bb_test[..., 1], bb_gt[..., 1])
IndexError: index 1 is out of bounds for axis 1 with size 1

xx1 = np.maximum(bb_test[..., 0], bb_gt[..., 0])
ValueError: operands could not be broadcast together with shapes (0,) (1,2)

getting these two error while running

I am also getting similar issue
were you able to resolve it?
' xx1 = np.maximum(bb_test[..., 0], bb_gt[..., 0])', 'ValueError: operands could not be broadcast together with shapes (0,) (1,32)

@marunava21 @day-night-py check the detections you're passing to tracker, even if there are no detections just pass "np.empty((0, 5))".

@sauravns Thanks for the suggestion, i solved the issue

@sauravns Thanks for the suggestion, i solved the issue

How did you solve the error, can you please explain?
I'm facing the same error.

I am also getting similar error. Any idea what could be the issue?

Thanks @sauravns for the suggestion.. In the iou_batch() function, we should check whether detection length and if its 0 then set the detection to empty numpy array,

def iou_batch(bb_test, bb_gt):
"""
From SORT: Computes IOU between two bboxes in the form [x1,y1,x2,y2]
"""

if len(bb_test) == 0:
    bb_test = np.empty((0, 5))

...
...

谢谢@sauravns对于建议..在iou_batch()函数中，我们应该检查检测长度是否为0，然后将检测设置为空numpy数组，

def iou_batch(bb_test, bb_gt): """ 来自 SORT：以 [x1,y1,x2,y2] 形式计算两个 bbox 之间的 IOU """

if len(bb_test) == 0:
    bb_test = np.empty((0, 5))

……​

Thank you!!
