Question

我正在使用一段代码，该代码应该能够通过某些训练有素的模型从图像中检测道路损坏。这是检查数据集统计信息以计算总图像和标签数量的代码的一部分。 xml.etree错误

from xml.etree import ElementTree
from xml.dom import minidom
import collections
import os
import matplotlib.pyplot as plt
import matplotlib as matplot
import seaborn as sns
%matplotlib inline



cls_names = []
total_images = 0
for gov in govs:

    file_list = os.listdir(base_path + gov + '/Annotations/')

    for file in file_list:

        total_images = total_images + 1
        if file =='.DS_Store':
            pass
        else:
            infile_xml = open(base_path + gov + '/Annotations/' +file)
            tree = ElementTree.parse(infile_xml)
            root = tree.getroot()
            for obj in root.iter('object'):
                cls_name = obj.find('name').text
                cls_names.append(cls_name)
print("total")
print("# of images：" + str(total_images))
print("# of labels：" + str(len(cls_names)))

我希望显示的图像数量和标签数量

该异常表明您尝试加载的文件之一格式不正确。尝试将ElementTree.parse()部分的try...except括起来，并打印文件名，以便查看哪个文件有问题。

更新：

from xml.etree import ElementTree, ParseError
from xml.dom import minidom
import collections
import os
import matplotlib.pyplot as plt
import matplotlib as matplot
import seaborn as sns

cls_names = []
total_images = 0
for gov in govs:

    file_list = os.listdir(base_path + gov + '/Annotations/')

    for file in file_list:

        total_images = total_images + 1
        if file =='.DS_Store':
            pass
        else:
            try:
                infile_xml = open(base_path + gov + '/Annotations/' +file)
                tree = ElementTree.parse(infile_xml)
                root = tree.getroot()
                for obj in root.iter('object'):
                    cls_name = obj.find('name').text
                    cls_names.append(cls_name)
            except ParseError:
                 print("Parse error with %s", file) 
print("total")
print("# of images：" + str(total_images))
print("# of labels：" + str(len(cls_names)))

如何修复ParseError：格式不正确（无效的令牌）：Python中的第1行，第0列
