xml__0">LabelImg 无法保存修改后xml 文件

今天标注数据，忽然发现无法保存修改之后的xml 文件，保存之后重新打开还是修改之前的xml

查看LabelImg信息如下：

Img: F:\Fan\own\6016\picture\S1000007.jpg -> Its xml: F:\Fan\own\6016\picture\S1000007.xml
Traceback (most recent call last):
  File "<string>", line 1197, in verifyImg
  File "<string>", line 1269, in saveFile
  File "<string>", line 1298, in _saveFile
  File "<string>", line 785, in saveLabels
  File "Z:\home\darrenl\tmp\labelImg\build-tools\build\labelImg\out00-PYZ.pyz\libs.labelFile", line 56, in savePascalVocFormat
  File "Z:\home\darrenl\tmp\labelImg\build-tools\build\labelImg\out00-PYZ.pyz\libs.pascal_voc_io", line 121, in save
  File "Z:\home\darrenl\tmp\labelImg\build-tools\build\labelImg\out00-PYZ.pyz\codecs", line 878, in open
IOError: [Errno 13] Permission denied: u'F:\\Fan\\own\\6016\\picture\\S1000007.xml'

这里提示权限不足，查看F:\Fan\own\6016\picture\S1000007.xml 文件下面的属性，发现是只读属性，

解决办法：
将文件夹里面的xml去掉只读属性，再次修改后即可保存。
