此将.xml文件转换为KITTI文件的Python脚本不会输出转换后的文件

Question

import os
from os import listdir, getcwd
from lxml import etree

wd = getcwd()

if not os.path.exists(wd + "/labelsKitti/"):
    os.mkdir(wd + "/labelsKitti/")
k = 1
for dirName, subdirList, nameFile in os.walk(wd + "/Annotations/"):

    for nameF in nameFile:

        nameF = nameF.replace(".xml", "")

        doc = etree.parse(wd + "/Annotations/" + nameF + ".xml")
        raiz = doc.getroot()
        labelkitti = open("%s/labelsKitti/%s.txt" % (wd, nameF), "w")

        for n in range(len(raiz)):

            if raiz[n].tag == "object":

                name = raiz[n].find("name").text

                if raiz[n].find("truncated") is None:
                    truncated = float(0)
                else:
                    truncated = float(raiz[n].find("truncated").text)

                occluded = int(0)  # Ignored by DetecNet
                alpha = float(0)  # Ignored by DetecNet
                bbox_xmin = float(raiz[n].find("bndbox/xmin").text)
                bbox_ymin = float(raiz[n].find("bndbox/ymin").text)
                bbox_xmax = float(raiz[n].find("bndbox/xmax").text)
                bbox_ymax = float(raiz[n].find("bndbox/ymax").text)
                dimHeight = float(0)  # Ignored by DetecNet
                dimWidth = float(0)  # Ignored by DetecNet
                dimLength = float(0)  # Ignored by DetecNet
                locationX = float(0)  # Ignored by DetecNet
                locationY = float(0)  # Ignored by DetecNet
                locationZ = float(0)  # Ignored by DetecNet
                rotationY = float(0)  # Ignored by DetecNet

                labelkitti.write("%s" % (name))
                labelkitti.write(" ")
                labelkitti.write("%.2f" % (truncated))
                labelkitti.write(" ")
                labelkitti.write("%.0f" % (occluded))
                labelkitti.write(" ")
                labelkitti.write("%.2f" % (alpha))
                labelkitti.write(" ")
                labelkitti.write("%.2f" % (bbox_xmin))
                labelkitti.write(" ")
                labelkitti.write("%.2f" % (bbox_ymin))
                labelkitti.write(" ")
                labelkitti.write("%.2f" % (bbox_xmax))
                labelkitti.write(" ")
                labelkitti.write("%.2f" % (bbox_ymax))
                labelkitti.write(" ")
                labelkitti.write("%.2f" % (dimHeight))
                labelkitti.write(" ")
                labelkitti.write("%.2f" % (dimWidth))
                labelkitti.write(" ")
                labelkitti.write("%.2f" % (dimLength))
                labelkitti.write(" ")
                labelkitti.write("%.2f" % (locationX))
                labelkitti.write(" ")
                labelkitti.write("%.2f" % (locationY))
                labelkitti.write(" ")
                labelkitti.write("%.2f" % (locationZ))
                labelkitti.write(" ")
                labelkitti.write("%.2f" % (rotationY))
                labelkitti.write("\n")

        labelkitti.close()

该脚本将创建labelsKitti文件夹，但是该文件夹中没有任何已转换的文件。我尝试调试代码，但是仍然无法运行。我还尝试过事先创建文件夹，并尝试将xml文件放在同一目录中，但到目前为止没有任何效果。
