蚂蚁蜜蜂分类数据集下载链接：https://download.pytorch.org/tutorial/hymenoptera_data.zip

要实现如图操作：

• 将ants分为ants_image和ants_label

• 将bees分成bees_image和bees_label
  

• 创建ants_label和bees_label，并且以图片名作为txt文件的名称，将标签写入到txt文件中
  
  

• 将标签写入到txt文件中

1、创建python文件，与数据集dataset同一路径下

2、对divide_data.py进行编辑

import osroot_dir = "dataset/train"# 原训练集的标签
label1 = "ants"
label2 = "bees"# 训练文件夹下的原始文件夹ants和bees
original_dir1 = os.path.join(root_dir, "ants")
original_dir2 = os.path.join(root_dir, "bees")# 将原始文件夹名称分别改为ants_image和bees_image
target_dir1 = os.path.join(root_dir, "ants_image")
target_dir2 = os.path.join(root_dir, "bees_image")# 获取标签并创建的标签文件夹ants_label和bees_label
target_label_dir1 = os.path.join(root_dir, "ants_label")
target_label_dir2 = os.path.join(root_dir, "bees_label")"""判断是否存在文件夹：1、如果存在ants和bees，就将它们改为ants_image和bees_image2、判断是否存在ants_label和bees_label，如果不存在就创建文件夹
"""
if os.path.exists(target_dir1):print(f'{target_dir1}已存在')else:if os.path.exists(original_dir1):os.rename(original_dir1, target_dir1)print(f'{original_dir1}已修改为{target_dir1}')if os.path.exists(target_dir2):print(f'{target_dir2}已存在')
else:if os.path.exists(original_dir2):os.rename(original_dir2, target_dir2)print(f'{original_dir1}已修改为{target_dir1}')if os.path.exists(target_label_dir1):print(f'{target_label_dir1}已存在')
else:os.mkdir(target_label_dir1)print(f'已成功创建{target_label_dir1}')if os.path.exists(target_label_dir2):print(f'{target_label_dir2}已存在')
else:os.mkdir(target_label_dir2)print(f'已成功创建{target_label_dir2}')"""将图片的label保存在以图片名命名的txt文件中：1、获取ants_image和bees_image中的图片名2、以每张图片名来命名txt文件，将其保存在ants_label和bees_label中
"""
img_path1 = os.listdir(target_dir1)
img_path2 = os.listdir(target_dir2)def write_txt(img_path, target_label_dir, label):for name in img_path:file_name = name.split('.jpg')[0]with open(os.path.join(target_label_dir, "{}.txt").format(file_name), 'w') as f:f.write(label)print(f'已成功写入{target_label_dir}')write_txt(img_path1, target_label_dir1, label1)
write_txt(img_path2, target_label_dir2, label2)

3、运行py文件python divide_data.py
