YOLOX&NEU-DET钢材表面缺陷任务划分数据集

划分数据集:
make_txt.py(用于划分数据集)

import os
import random

trainval_percent = 0.9
train_percent = 0.9
xmlfilepath = 'Annotations'
txtsavepath = 'ImageSets'
total_xml = os.listdir(xmlfilepath)

num = len(total_xml)
list = range(num)
tv = int(num * trainval_percent)
tr = int(tv * train_percent)
trainval = random.sample(list, tv)
train = random.sample(trainval, tr)

ftrainval = open(txtsavepath + '/trainval.txt', 'w')
ftest = open(txtsavepath + '/test.txt', 'w')
ftrain = open(txtsavepath + '/train.txt', 'w')
fval = open(txtsavepath + '/val.txt', 'w')

for i in list:
    name = total_xml[i][:-4] + '\n'
    if i in trainval:
        ftrainval.write(name)
        if i in train:
            ftrain.write(name)
        else:
            fval.write(name)
    else:
        ftest.write(name)

ftrainval.close()
ftrain.close()
fval.close()
ftest.close()

运行结果如下:

tips: 这里是voc2yolo哈不是xml2yolo!!所以运行代码前检查一下自己的数据标注的格式,一定要是pascalvoc格式的xml哦,标签有difficult等的
