AttributeError: module 'numpy' has no attribute 'int'.

Hi,
I am trying to run training session of BoxInstSeg, and recieved the following error:
```
File "/home/ubuntu/***/projects/BoxInstSeg/mmdet/datasets/pipelines/loading.py", line 653, in _generate_mask_from_box
    gtboxes = results['gt_bboxes'].round().astype(np.int)
```
I am using the latest repository of BoxInstSeg, and my numpy version is 1.26.3.
Thanks
