AttributeError: 'NoneType' object has no attribute 'text'

I encountered an issue during the evaluation phase that seems related to the missing pose attribute in the Pascal VOC XML files.Is there a specific way the parse_rec function or Pascal VOC evaluation is expected to handle missing tags such as pose? The complete error message is as follows:
