删除多边形时出错，如下

[INFO   ] __init__:get_config:71 - Loading config file from: /home/fl/.labelmerc
Traceback (most recent call last):
  File "/home/fl/anaconda3/envs/labelme/lib/python2.7/site-packages/labelme/app.py", line 1866, in deleteSelectedShape

    self.labelList.removeItem(item)

    self.model().removeRows(index.row(), 1)
  File "/home/fl/anaconda3/envs/labelme/lib/python2.7/site-packages/labelme/widgets/label_list_widget.py", line 102, in removeRows
    ret = super().removeRows(*args, **kwargs)
TypeError: super() takes at least 1 argument (0 given)

是python用法问题，参见https://blog.csdn.net/u010812071/article/details/76038833

所以编辑
/home/fl/anaconda3/envs/labelme/lib/python2.7/site-packages/labelme/widgets/label_list_widget.py

改为如下即可

    def removeRows(self, *args, **kwargs):
        ret = super(StandardItemModel, self).removeRows(*args, **kwargs)
        self.itemDropped.emit()
        return ret
