数据集导出的一个bug

[akhzz]

环境
Windows 11，Python 3.7.9，PaddleLabel 1.0.1

语义分割数据集导出的时候，导出格式为掩膜 灰度，终端报错
ERROR [root] Export dataset failed
Traceback (most recent call last):
File "d:\program files\python37\lib\site-packages\paddlelabel\task\instance_segmentation.py", line 96, in draw_mask
cv2.line(catg_mask, (prev_w, prev_h), (w, h), color, line_width)
cv2.error: OpenCV(4.5.4) D:\a\opencv-python\opencv-python\opencv\modules\imgproc\src\drawing.cpp:1801: error: (-215:Assertion failed) 0 < thickness && thickness <= MAX_THICKNESS in function 'cv::line'

During handling of the above exception, another exception occurred:

Traceback (most recent call last):
File "d:\program files\python37\lib\site-packages\paddlelabel\api\controller\project.py", line 185, in export_dataset
exporter(**params)
File "d:\program files\python37\lib\site-packages\paddlelabel\task\semantic_segmentation.py", line 182, in mask_exporter
mask = draw_mask(data, mask_type=seg_mask_type)
File "d:\program files\python37\lib\site-packages\paddlelabel\task\instance_segmentation.py", line 101, in draw_mask
abort(detail=e.msg, status=500, title="cv2 error")
File "d:\program files\python37\lib\site-packages\paddlelabel\api\util.py", line 25, in abort
headers={"charset": "utf-8"},
connexion.exceptions.ProblemException

在paddlelabel\task\instance_segmentation.py中添加日志发现line_width有负数
DEBUG [paddlelabel.instance_segmentation.91]: line_width is 141
DEBUG [paddlelabel.instance_segmentation.91]: line_width is -15

您好，请问这样的报错怎么解决呀？

您好，请问这样的报错怎么解决呀？

我在报错的前面加了一个判断
if line_width < 0: line_width = 1，把有问题的跳过了，然后就不报错了，实际上只是让程序能接着运行，原来报错的那一部分导出的标注会有错误
